M1 Garand, History and Disassembly

 I shamelessly clipped this from "American Rifleman".  In honor of my poor departed Garand that I lost in that durn kayak accident *Sniff*Sniff*, Those Kayaks should be registered as "Lethal Weapons". for the havoc they cause to the gun owning community.

A History of the M1 Garand

During World War I, the United States Army experimented with a number of different machine gun designs, and the news reports of the tests got a young inventor thinking about, and eventually designing, a machine gun of his own. His initial attempt was a primer-actuated light machine gun he submitted to the National Bureau of Standards, which had instructed him to make a model of it. That design became the basis for what would, eventually, become the M1 rifle—commonly called the “Garand” after its inventor, John Cantius Garand.

Garand, who became a Springfield Armory employee in 1919, had an extensive background in design and production. Once at Springfield, he was tasked with designing a semi-automatic shoulder rifle based upon his earlier machine gun. He worked on and improved the design for the next 17 years. The now-familiar M1 was finally adopted on January 9, 1936, the rifle was adopted as the “U.S. Rifle, Cal. .30, M1.”

Early production rifles used a “gas trap” instead of the later “gas port” design and initially did not perform as well as expected, but once the “bugs” were worked out, the rifle was favorably received. It was fed by an eight-round en-bloc clip that was ejected along with the last spent casing, locking the bolt back and leaving the receiver open for a fresh clip to be inserted. User-friendly, accurate and chambered for the powerful ​​​
.30-’06 Sprg. cartridge, the M1 gained a reputation as a hardy and well-made service rifle.

World War II was the rifle’s baptism of fire, and it performed admirably. To a man, the G.I.s put their faith in their M1 rifles and took them from North Africa to Okinawa. Along the way, Garand made more improvements to the rifle based upon field experience and soldiers’ comments.

Although late to adopt the rifle, the Marines liked it, too, and found it well-suited for jungle fighting. America was the only country to equip its fighting men with a semi-automatic rifle as a standard shoulder arm. The venerability of the rifle was further established in the Korean War.

The M1 rifle is not without faults. At just under 10 lbs. it is heavy and the en-bloc clip does not allow for easy “topping off.” Because of those drawbacks, America sought a high-capacity, fully automatic rifle for individual soldiers. Reliability and accuracy were paramount, however, and the M1 was the measuring stick. What later became the M14 was based upon the M1.

Combined, Springfield Armory and Winchester Repeating Arms manufactured more than 4 million M1s during World War II. International Harvester and Harrington & Richardson manufactured them as well, and, during the Korean War, more than 500,000 were made.

The rifle is considered one of the finest ever produced by American armories. Its popularity is evidenced by its representation on the firing line at Camp Perry and other highpower rifle matches to this day. It is accurate, robust and its service record speaks for itself.

Disassembly

Disassembly of the unloaded M1 rifle begins by pulling the bolt rearward until it locks back. Visually inspect the chamber to ensure it is not loaded, then press down on the slide and follower while holding the operating rod and ease the bolt forward. Do this carefully or you will end up with a case of “M1 thumb”—a highly unpleasant condition!

Once this is done, disassembly can begin. Pull rearward on the trigger guard (53) and then out and away from the stock. The entire trigger housing (54) and assembly will separate from the rifle (Fig. 1). Lift the receiver (44) and assembly away from the stock.

Disengage the follower rod (22) from the follower arm (20) by moving the rod toward the muzzle. Remove the rod and operating rod spring (40). Next, push out the follower arm pin (21) from the receiver’s left side. Then lift away the bullet guide (5),

follower arm and operating rod catch (39) (Fig. 2). Reach down into the receiver and lift out the slide and follower (46).

Continue disassembly by pulling the operating rod (38) rearward until the rear surface of the handle is directly under the forward edge of the windage knob on the rear sight. Disengage the guide lug on the operating rod through the dismount notch on the receiver with upward and outward pressure on the handle of the operating rod (Fig. 3). The rod should now come free from the receiver. Remove the bolt (4) by grasping it and sliding it forward while lifting upward and outward with a rotating motion (Fig. 4).

With a large, blunt screwdriver, unscrew and remove the gas cylinder lock screw (30). Unscrew and remove the gas cylinder lock (29). Next, remove the gas cylinder (28) by sliding it forward and off the barrel. If the gas cylinder is tightly attached, rap on the bayonet stud with a nylon hammer or piece of soft wood to loosen it. Do not burr or damage the internal splines. The front handguard (23) may then be moved forward and off the barrel.

This is all that is needed for basic cleaning. All other bolt and trigger housing disassembly and parts replacement should be done by a competent gunsmith. Reassembly of the M1 is in the reverse order. 

A few precautions: The operating rod for the M1 has a bend that is intentional, and it should never be hammered on or straightened out. The crown of the operating rod should also be kept bright by using a solvent and nylon brush. Do not scrub with a metal brush or other harsh abrasive. The tolerances within the gas operating system are quite close and nothing should be used that can affect the system.

All operating parts should have a light coat of lubrication except the inside of the gas cylinder. This should be free of carbon deposits and other fouling, but should be kept dry

The International Harvester Garand, The Rifle for the Nuclear Age

I am on vacation and I am using my baby laptop and blogging on this laptop is better than using my phone...but not by much, the curser will "wander" and if I am not paying attention, it will move and I will find myself putting my writings in the middle of the prior paragraph.   And yes it happened several times on this blog post. 

    I always had a fascination with the Garand, and I have had Blogged about the Garand and had adventures with the rifle, ...until my lamented kayak accident *Sniff, Sniff*

My Son Shooting my Winchester Garand before the tragic Kayak Accident *sniff*sniff*

I had  wondered about the fuss about the IH Garand, but I never asked "why".  After reading the article from "American Rifleman" I now understand the reasoning and the fascination

.At the conclusion of World War II, the M1 Garand had garnered a well-deserved reputation as the best standardized service rifle of the conflict. Large numbers of Garands were in inventory after Victory over Japan Day, and it was assumed they were sufficient to meet the needs of our armed forces for the foreseeable future. Five years later, though, this illusion was shattered when hostilities commenced on the Korean Peninsula.

Many of the M1 rifles left over from World War II were taken from storage and refurbished for issue to troops departing overseas. To augment the supply of existing rifles, the U.S. Ordnance Dept. elected to put the M1 rifle back into production. Springfield Armory ramped up its Garand production line as quickly as possible, but additional sources were needed. As was often the case in previous wars, the government turned to civilian firms for production of all manner of military items, including firearms.

On June 15, 1951, the Ordnance Dept. granted a contract for 100,000 M1 rifles to the International Harvester Co (IHC). The rifles were to be manufactured at the firm’s Evansville, Ind., plant with deliveries scheduled to begin in December 1952. The Evansville facility was built during World War II by the Republic Aviation Corp. for production of the P-47 Thunderbolt fighter.

In 1945, International Harvester bought the former aircraft factory and converted it for manufacture of farm implements and refrigeration and air conditioning units. The selection of International Harvester was, to say the least, a rather interesting choice. Although the company manufactured vehicles—including half-tracks, trucks and tractors—during World War II, the firm had never made firearms, either civilian or military.

One of the major reasons behind the government’s seemingly unusual selection of International Harvester to produce M1 rifles was the plant’s geographic location. All of the more than 4 million M1 rifles that had been previously made by Springfield Armory and Winchester were manufactured within a radius of about 60 miles (the distance between Springfield, Mass., and New Haven, Conn.).

This may not have seemed important in the late 1930s or early 1940s, but the dawn of the Atomic Age put it in an entirely different perspective. Since most of the established armsmakers were in the New England area, a nuclear attack on the Eastern Seaboard could conceivably cripple the manufacture of military small arms in the United States.

The Department of Defense established a policy of geographic dispersion of vital defense production to mitigate vulnerability to a nuclear strike. The fact that Evansville, Ind., and Springfield, Mass., are more than 800 miles apart was seen as an important reason for selecting International Harvester to supplement Springfield Armory’s M1 rifle production.

Actually, the selection of a commercial enterprise that had never previously manufactured firearms for the military was not without precedent. During World War II, nine of the 10 prime contractors that manufactured the M1 carbine had never produced firearms before the war (the sole exception was Winchester). As was the case with the carbine manufacturers, plans were formulated for IHC to utilize a number of subcontractors to assist its Garand production program.

There are three known variations of International Harvester hammer drawing numbers. The earliest were “C-5546008 IHC.” Mid-production were “IHC C5546008”, while the final were “5546008 IHC” along with a single letter-code marking.

The serial number ranges assigned to IHC for M1 rifle production were: 4,400,000–4,660,000 and 5,000,501–5,278,245. In order to augment Springfield Armory’s and International Harvester’s M1 rifle production, a contract was also granted to the Harrington & Richardson Arms Co. on April 3, 1952, for the manufacture of 100,000 Garand rifles with additional contracts to follow. 

As International Harvester began to gear up for M1 manufacture, the firm was immediately faced with a number of daunting challenges, exacerbated by the fact the company had no prior firearm-making experience. Since the company had expertise in making complex machinery, such as trucks and tractors, it assumed making rifles wouldn’t be any different.

It is reported that IHC’s management planned to make the Garand rifles using standard machine tools already on hand rather than acquire specialized firearm-making machinery and to begin delivering rifles by Christmas 1952. The firm soon found this was impractical. A large number of unexpected problems arose, which caused a lot of consternation and resulted in a significant delay in starting rifle production.

Other than the receiver, one of the most challenging M1 components to manufacture was the barrel, and production was subcontracted to the Line Material Corp. The Milwaukee-based firm was an established maker of various equipment used in the transmission of electrical and telephone lines and had a well-regarded engineering and manufacturing team. In addition to making barrels for use by International Harvester, Line Material also supplied a large number of M1 rifle barrels to various ordnance depots for use in rebuilding Garands.

Receiver heel markings on IHC-produced M1 Garand rifles varied in the format of their stamped lettering, ranging from (l. to r.): the “Arrowhead” style, to the “Postage Stamp” style, to the “Gap Letter” style, in the latter case an earlier example.

It was soon widely acknowledged that the company’s barrels were of the highest quality. Line Material increased its capacity by adding a second shift to meet the demand for barrels for rebuilds and to supply IHC’s fledging Garand production program. It is reported that Line Material sent some barrels directly to ordnance units in Korea for use in overhauling M1 rifles in theater. 

The barrels were marked “LMR” on the right side and were stamped with the drawing number (“D653448”), month and year of production, heat lot identification, “P” (proof) and “M” (magnetic particle inspection). Except for very early examples, the barrels made under subcontract for International Harvester can be identified by a punch mark between the “LMR” and the drawing number.

The high quality of the LMR barrels and their availability were among the few things to go smoothly with International Harvester’s M1 rifle production program. As IHC’s production problems became apparent, Springfield Armory dispatched John Garand’s chief tool and die maker, John Stimson, to Indiana to assist the company in setting up its production line. Once production was underway, a plethora of functioning glitches arose, including a serious jamming problem that completely shut down the assembly line for three months until the cause could be discovered and a remedy devised.

The drawing numbers of major parts on International-produced Garands typically include the “IHC” denotation. Examples include (r., top to bottom): the operating rod, bolt and receiver. Harrington & Richardson made M1 Garand receivers of its own (upper l.) as well as supplying them to IHC (lower l.).

The company received assistance from both Springfield Armory and H&R (which was concurrently manufacturing M1 rifles by that time). Harrington & Richardson engineers eventually determined that the jamming problem was due to incorrect specifications for spring-tension settings. Other problems cropped up and were solved one by one, but IHC was never able to meet its contractual production schedule.

In order to help International Harvester get into Garand production as expeditiously as possible, a number of parts were procured from other sources. Interestingly, one of those parts was the most basic component of the rifle—the receiver. In addition to receivers actually made in house by IHC, the company utilized receivers made by Springfield Armory and H&R. There were four distinct variations of M1 receivers manufactured by Springfield for International Harvester.  

The first receivers made by Springfield Armory for International Harvester were in the approximate 4,440,000-4,441,100 serial number range and, for the most part, were consecutively numbered. Although marked “International Harvester,” the logo markings on the receiver were applied by Springfield Armory, and serial numbers were stamped at the IHC plant.

Most of these receivers were fitted with LMR barrels, although a few were fitted with Springfield Armory-made barrels. Collectors have dubbed this variant SA/IHC receiver as the “Arrowhead” due to the layout of the nomenclature markings which, with a bit of imagination, resemble an arrowhead with a broken tip. 

Soon after rifles with the SA/IHC “Arrowhead” receivers started to be assembled, the previously mentioned problem with function-firing difficulties surfaced. Once the problem was identified and solved, IHC began using unfinished Springfield Armory receivers that were on hand. Rather than stamping the receiver logo markings with “arrowhead” format, IHC chose to stamp them with a format consisting of four even lines.

This variant is known as the “Postage Stamp” SA/IHC receiver. Like the “Arrowhead” receivers, these were stamped
 with the Springfield Armory drawing number (“D 652891”), revision numbers (“42” or “43”), and heat lot numbers indicating production by Springfield. Most of the rifles were assembled with LMR barrels (typically dated late 1952 or early 1953), but it is believed some Springfield Armory barrels (dated early 1953) were utilized as well.

The next variation of M1 rifle receiver supplied to International Harvester by Springfield was the so-called “Gap Letter” type in recognition of the noticeable space between the centers of the first two lines of the nomenclature logo. The reason for this change in the format of the nomenclature is not known.

The final variant of receiver made by Springfield Armory and supplied to International Harvester was the “Gap Letter” variety serially numbered in the assigned range 5,198,034 to 5,213,034, representing about 15,000 numbers. These receivers were acquired from SA by IHC to complete its production commitments. 

To its credit, Harrington & Richardson did a great deal to assist International Harvester throughout the latter entity’s M1 production program. As IHC was winding down rifle manufacture, the company needed additional receivers to complete its production commitments. To this end, a relatively small quantity of M1 receivers (approximately 4,000) was supplied to IHC by H&R.

Those receivers fall into the approximate 5,213,034 to 5,217,065 serial number range. Interestingly, the logo nomenclature on them was apparently stamped by International Harvester (“Postage Stamp” profile) while the serial number and the drawing number on the receiver leg were applied by HRA. 

Following is a summary of the type and quantity of M1 receivers manufactured for International Harvester by Springfield Armory and Harrington & Richardson:

SA/IHC “Arrowhead” 4,440,000–4,441,100...................1,100

SA/IHC “Postage Stamp” 4,441,000–4,445,600...800–900

SA/IHC “Gap Letter” 4.6 M 4,638,000–4,660,000...22,000

SA/IHC “Gap Letter” 5M 5,198,034–5,211,600..........13,243

HRA/IHC 5,213,034–5,217,065...........................................4,000

Although Springfield and H&R supplied International Harvester with a number of receivers, the vast majority of the company’s M1 receivers were made by IHC. All of those were of the “Postage Stamp” variety. The receiver drawing number marked on the right side of the receiver leg was initially “IHC D6528291,” which was later changed to “D6528291” (no “IHC” prefix). 

The majority of barrels used by International Harvester were made by Line Material (“LMR” marked), although some Springfield barrels were used, mainly very early and, again, near the end of the company’s M1 rifle production program.

IHC contracted with other manufacturers to complete its rifles. Examples include the “LMR”-marked barrel made by Line Material Corp (top) along with other components such as the “DRC”-marked windage knob and “NHC”-marked gas plug (above)

The major components such as the bolt, operating rod, trigger housing, hammer, gas cylinder lock screw and rear sight windage and elevation knobs were generally marked “IHC” along with the appropriate drawing number and/or subcontractor initials. Although unmarked, IHC M1 front sights were typically characterized by the noticeably wider space between the two flared protective “ears,” approximately 0.875" across, wider than any other manufacturer.

As with many of the other components, the manufacture of stocks by International Harvester did not proceed as smoothly as originally envisioned. Initial plans were for IHC to make the stocks and fore-ends rather than using subcontractors—as was done for a number of other components. As events transpired, though, most of IHC’s stocks were manufactured by subcontractors, chiefly the S.E. Overton Co. A hallmark of IHC M1 stocks is the presence of numbers stamped in the “barrel channel.”

Although three-digit numbers have been reported, the overwhelming majority are four digits, sometimes with a letter prefix or suffix. These numbers are believed to represent a variation of the Julian dating system. International Harvester was the only manufacturer to utilize stocks stamped with such numbers. The profile of the stock behind the receiver heel on the IHC Garand was noticeably narrower than found on the contemporary H&R M1 stocks.

IHC front sights, although unmarked, measure wider across their protective ears than do those of other makers’ rifles.

Although three-digit numbers have been reported, the overwhelming majority are four digits, sometimes with a letter prefix or suffix. These numbers are believed to represent a variation of the Julian dating system. International Harvester was the only manufacturer to utilize stocks stamped with such numbers. The profile of the stock behind the receiver heel on the IHC Garand was noticeably narrower than found on the contemporary H&R M1 stocks.

Early production IHC stocks were stamped with an Ordnance escutcheon emblem (“crossed cannons”) on the right side of the stock and a small—and often indistinct—“P” proof firing mark stamped on the bottom of the pistol grip. This was the only known case of a final inspection stamp on a post-war M1 rifle being applied to the right side of the stock.

Slightly later examples typically had the more commonly seen “circled P” proofmark (sans serif) applied to the face of the grip but still had the “crossed cannons” escutcheon stamped on either the left or right side. Circa October 1953, in the approximate 4.45 million serial number range, the “crossed cannons” stamp was replaced by a 1/2" Defense Acceptance Stamp on the left side of the stock. 

The 1/2”-tall Defense Acceptance Stamp (top) replaced the “crossed cannons” in October 1953. Overton was the chief supplier of IHC stocks. It also, uncharacteristically, stamped the barrel channels with a three- or four-digit number (below).

International Harvester eventually accepted additional M1 production contracts totaling 418,443 rifles. Despite numerous setbacks and glitches experienced throughout the production program, the company worked diligently to overcome every obstacle put in its path, self-inflicted and otherwise. Just when it appeared that the company was going to successfully complete its M1 rifle production commitments, another complication arose.

In September 1955, IHC’s parent company negotiated a sale of the Evansville facility to the Whirlpool Corp. To add insult to injury, the sales contract mandated that Whirlpool take possession of the plant in January 1956. Since IHC had completed just over 300,000 rifles to date, it would have been impossible to finish the remaining 100,000 or so rifles called for in the contract in just two months’ time. This resulted in IHC having to negotiate an early “buyout” of the final contract. The following represents the total of rifles production from fiscal years 1953-1956:

Fiscal Year       Quantity Delivered
1953                     6,804
1954                     82,897
1955                     175,736
1956                     72,186
Total                  337,623

International Harvester’s M1 production program was obviously a source of consternation and almost continual headaches for the company. In hindsight, senior management (and likely stockholders as well) probably questioned the wisdom of getting involved in making military rifles. It was undoubtedly one of those, “It seemed like a good idea at the time” situations. Even though the company had to negotiate an early termination of its contract, it nontheless persevered and eventually made more than 337,000 M1 rifles by the time production ceased in December 1955.

The IHC people may not have been very proficient at making Garands but they can’t be accused of being quitters. 
Despite the numerous problems experienced by the company, an International Harvester M1 Garand is every bit as serviceable as those made by any other manufacturer. The International Harvester M1 has become one of the more popular examples of the genre among many collectors today due to the number of receiver variations and their relative scarcity as compared to Springfield Armory-made Garands of the same era. 

Prior to the late 1970s, IHC M1s were rather hard to find on the domestic civilian market as compared to those made by other manufacturers. In the late 1950s and into the 1960s, many late-production Garands—especially Springfields and International Harvesters—were shipped to various countries under military foreign-aid programs. This accounts for the prior relative scarcity of the IHC rifles as well as Springfields in the very high number serial number range of 5.9 to 6.0 million.

While a few H&R Garands were also shipped to some allied nations, for some reason during this period, the bulk of these rifles seemed to be from International Harvester. Once the rifles were supplied to foreign governments, they could not be “re-imported” back into the United States for sale on the civilian market. Circa 1977-1978, a clause in the regulations permitted some of these former military rifles to be brought back to the United States, but sales were restricted to full-time law enforcement officers.

Quite a few rifles changed hands in this manner and, in the span of a couple of years, IHC M1s went from being quite scarce to being not particularly uncommon. The regulations were eventually tightened up to prohibit such sales, and the spigot was soon closed on the re-importation of IHC Garands. Not too many years later, the Director of Civilian Marksmanship and its successor, the Civilian Marksmanship Program (CMP), acquired significant numbers of Garands—including some IHCs—from overseas, and they were openly sold on to qualified buyers. As of this writing, the CMP periodically has IHC Garands available for sale. 

Perhaps surprisingly, in light of the extensive production problems experienced with the M1 rifles, it has been reported that the Ordnance Dept. later approached International Harvester about the possibility of manufacturing M14 rifles under government contract. Perhaps not surprisingly, that did not come to pass. In hindsight, International Harvester likely wished it had stuck with making tractors instead of rifles. Regardless, an IHC M1 rifle is a sought-after collectible today and is a very interesting, albeit often confusing, part of the story of John Garand’s rifle.

M1 Garand Rebuilds History and Markings.

 

I ran across this Article, I have blogged about Garands before and I had a beautiful Garand until I "Lost her in that tragic Kayak Accident" *Sniff*Sniff*. I even bought a manual several weeks ago in remembrance of my Garand,

I picked up this manual a month ago in remembrance of my Garand*Sniff*Sniff*,I was in the Same Forest Park Army Navy Store and Picked up a sling for my new Rifle, I will talk about that rifle in a day or so in a blogpost. before it too gets lost in a canoe accident.....durn canoes......the lakes around here should be nicknamed "Iron bottom Sound", LOL  It seems to be endemic 
     I saw this article in American Rifleman, and it was talking about the Garand and the information was very detailed and I figured it was worth reproducing.




This article, "In the System: M1 Garand Rebuilds," appeared originally in the December 2003 issue of American Rifleman. To subscribe to the magazine, visit the NRA membership page here and select American Rifleman as your member magazine. Above: This member of a U.S. Army Ordnance unit during World War II is cleaning and repairing stacks of salvaged rifles, including many M1s. Such low-level repair and maintenance activities were very common, but substantial repair and modification required the services of a well-equipped ordnance depot or arsenal. 


Any mechanical object eventually requires some form of repair or refurbishment, and few objects are subjected to as much use and abuse as military rifles. Whether mishandled by careless recruits or subjected to hard use without cleaning or maintenance on the battlefield, virtually all military rifles require varying degrees of repair and maintenance during their tenure of service.

Basic cleaning and simple maintenance were the responsibility of the soldier, but often a rifle needed repair or maintenance to a degree beyond the capability of individuals. Most routine repair and maintenance procedures were performed by military ordnance personnel in the field or at rear echelon ordnance facilities.

Such work was referred to as “Third or Fourth Echelon Maintenance Responsibilities” in Ordnance manuals. If more extensive work was needed, the arms were sent to an arsenal or ordnance depot, usually in the United States, for overhaul, which was officially referred to as “Fifth Echelon Maintenance Responsibilities.”

Few U.S. military arms were manufactured in greater numbers or saw more extensive use than the venerable “U.S. Rifle, Cal. .30, M1” or M1 Garand. From its adoption in 1936 until production ceased in 1957, well over 5 million M1s were made, and the majority saw widespread service during World War II and the post-war era.

Whether carried in combat overseas or subjected to use by recruits in stateside training camps, virtually all M1s were eventually shipped to an ordnance facility for rebuild at some point, sometimes more than once. Rebuilding enabled worn or damaged rifles to be reclaimed and re-issued as essentially new guns.

This M1 rifle was rebuilt at Springfield Armory in 1947 and has a mixture of World War II and earlier parts. It has a modified operating rod, modified trigger housing pad, T105E1 rear sights and an “sa/shm” stock cartouche.


The first significant M1 overhaul occurred prior to 1941 when the so-called “Seventh Round Stoppage” problem arose. It was caused by improperly machined receivers. The production tooling was changed, and the issue quickly became a thing of the past. A number of very early M1s were modified at Springfield Armory to correct the deficiency.

A couple of years later, the original gas system, dubbed the “gas trap,” was found to be faulty, and an improved “gas port” system was adopted. In late 1940 and early 1941, some of the earlier gas trap rifles were rebuilt by Springfield Armory and converted to gas port configuration. Generally, only the barrels, gas cylinders and stocks were changed,  otherwise, the very early M1 rebuilds retained most of their original parts.

Even though Springfield Armory turned out large numbers of M1s during World War II, there was some limited overhaul of M1s during the active war. Most repair and refurbishment was done by overseas ordnance shops due to the difficulty of shipping large numbers of arms from combat zones to the “Zone of the Interior” (continental United States).

Many M1s that would have been overhauled in peacetime were kept in action by the hardworking ordnance personnel in the field or at small base shops. Although such cursory repair work enabled the rifles to continue in service until hostilities ceased, it resulted in large numbers of them needing substantial repair and overhaul at the war’s end. After 1945, the mission of Springfield Armory changed from M1 manufacture to M1 overhaul, along with other types of small arms.

While the specific type of modifications performed during overhaul varied depending on the type of arm being rebuilt, the general practices were similar. Technical Manuals, such as TM 9-1275, detailed the specific procedures to be performed and the equipment (gauges, tools, etc.) necessary for such work.

The War Department Technical Manual TM 9-1275, Ordnance Maintenance U.S. Rifles, Cal. .30, M1, M1C (Sniper’s) and M1D (Sniper’s), dated June, 1947, detailed the inspection, maintenance, repair and overhaul of M1 rifles in the post-World War II period. (Courtesy Chip Walker)


When M1 rifles were received by an ordnance facility for overhaul, they were unpacked, serial numbers recorded and the arms were degreased as necessary. They were broken down into the major groups; stock group, barrel group and trigger group. The metal parts, except the barrel, were removed and set aside for inspection and gauging.

The wooden components were inspected and repaired, refinished, or discarded as necessary. Barrels and receivers were inspected and gauged to make sure they were within “specs.” Any barrels that proved unusable—due to substantial pitting, wear or excessive throat erosion—were removed from their receivers and scrapped.

Receivers passing inspection were re-Parkerized as required. The other metal components were inspected and gauged. Parts passing inspection were placed in storage bins for subsequent use. Superseded (obsolete) components were replaced, and those that required modification for continued use were altered as necessary.

Major components specific to the M1 that required replacement or modification for continued use were:

Rear Sights: The improved T105E1 rear sight had been adopted near the end of World War II but was not utilized in rifles produced before the end of the war. After circa 1947, most M1s overhauled in ordnance depots had the earlier sights removed and the updated T105E1 pattern fitted.

The World War II-vintage operating rods were subject to cracking at the junction of the handle and tube. They were modified with a post-war relief cut (arrow)..


Some of the World War II-vintage “locking bar” rear sights were retained when the rifles were overhauled after the war, presumably due to a shortage of T105E1s. By the early 1950s, however, virtually all arsenal overhauled M1s were fitted with the updated rear sights.

Operating Rods: The original pattern was found to be subject to cracking at the juncture of the handle and tube. To alleviate the problem, a portion was milled away as part of the rebuild procedure. World War II and earlier vintage operating rods were modified by the addition of the relief cut modification.

Springfield manufactured large quantities of new operating rods with an integral relief cut marked “D35382” for replacement purposes after the war. To illustrate the large number of new operating rods needed for the extensive post-World War II rebuild programs, Springfield made 529,172 replacement M1 operating rods between Fiscal Years 1945 and 1948.

Trigger Housing Pads: From the beginning of production until the middle of World War II, M1 rifle trigger housings were manufactured with a raised portion, termed a “pad,” which was intended to function as a hammer stop.

Most World War II and earlier rear sights, such as the “locking bar” type (top, arrow), were replaced by the updated T105E1 variety (above) during the post-World War II rebuild process. By the 1950s, almost all M1s overhauled were re-equipped with the T105E1 units.


The original-size pad could sometimes interfere with proper operation of the hammer, and subsequent trigger housings were made with a smaller pad. Post-war rebuild standards specified that the earlier trigger housings have the large pads milled down.

Barrels: Although the basic configuration of the M1’s barrel did not change after World War II, many rifles sent in for overhaul had unsalvageable barrels due, in large measure, to the use of corrosive ammunition. Extreme wear and tear and improper cleaning also contributed to the problem. Springfield manufactured 563,310 new replacement barrels between Fiscal Years 1945 and 1948.

Stocks and Handguards: The basic configuration of the M1’s stock and handguards did not change after World War II. But the wooden components were less durable than most metal parts, and broken, cracked or otherwise unusable stocks and handguards were common.

Stocks and handguards with minor gouges or cracks were repaired by adding “plastic wood” or by inserting brass reinforcing screws and grinding them off  flush. Broken or worn stocks were salvaged by adding strips of wood along both sides near the bottom of the magazine area to allow the trigger housing to lock up tightly.

While such repairs might be considered unsightly to collectors, the ordnance workers were only interested in salvaging otherwise usable material and putting as many rifles back into serviceable condition as fast and as inexpensively as possible.

This Ordnance hang tag attached to an M1 denotes a rebuild at an arsenal or depot as evidenced by the wording “Repairs Required Beyond 4th Echelon Maint.”


A number of newly made replacement stocks were also fabricated after the war. Between Fiscal Years 1945 and 1948, Springfield made 291,971 replacement stocks. Compared to stocks, handguards were much more prone to damage and were less suitable for repair as illustrated by the number of replacement handguards fabricated by Springfield during the same period: 787,307 front and 893,736 rear handguards.

The above-discussed parts were not the only components needing replacement or modification during overhaul. Indeed virtually all parts of the M1 rifle were subject to replacement, repair or modification.

U.S. Ordnance Overhaul Entities

Springfield Armory: After a rifle was overhauled, ordnance regulations required that the identity of the ordnance facility that performed the rebuild be stamped on the stock. If a rifle had previously been overhauled by the same entity, it was not necessary to re-stamp it, although this happened in some cases.

For rifles overhauled at Springfield Armory from circa November 1945 to August 1947, a cartouche consisting of “sa/shm” was stamped on the left side of the stock. “sa” identified Springfield Armory as the overhaul facility and “shm” represented Col. Stephen H. McGregor, commanding officer of the Armory during that period.

World War II-vintage stocks that were ­recycled for use after the war (and stamped “sa/shm”) often retained their original 1941-1945 factory inspection cartouche, thus two different stamps of different vintages may be encountered on the same stock.

After Col. McGregor’s departure from Springfield, several types of inspection stamps were used. “sa/spg” represented Stanley P. Gibbs, a civilian inspector who had worked at Springfield for many years and who inspected overhauled M1s until circa 1950. Gibbs’ stamp was similar to the original factory inspection stamp used on the early gas trap M1s made from 1936 to 1940.

In July 1950, Col. James L. Guion was posted to Springfield Armory as commanding officer. M1 rifles overhauled after Col. Guion took command of the Armory were stamped “sa/jlg” on the stock’s left side. A similar final inspection stamp was also used on newly made M1s when the production line reopened in the early 1950s.

The top “p” stamp on an M1 rifle’s grip (circled P) is the original factory proofmarking, while the lower marking—a “p” enclosed in a square box—is a post-war arsenal overhaul proof stamp.


When new M1 production began, use of the “sa/jlg” rebuild stamp ceased, and it was replaced by a rebuild stamp consisting of “sa”— often enclosed in a three or four cornered box. Many of these stamps also had a one or two letter code to identify the inspector who supervised the procedure.

This “sa” rebuild stamp was most commonly applied to the left side of the butt. This same type of rebuild stamp was used on many M1 rifles converted to M1D sniper configuration during this period, and the stamp was often hidden by the leather cheek pad found on the sniper rifles.

A number of M1 rifles overhauled at Springfield in 1952 were marked “sa-52” behind the rear sight. Some M1C sniper rifle receivers converted to M1 specifications by plugging the three holes drilled into the left side may also be found with this “sa-52” marking. Applying these markings on the receiver was a departure from the previous practice of stamping rebuild markings on the stocks, and it only lasted for one year.

Rock Island Arsenal: Unlike Springfield, Rock Island did not manufacture large quantities of replacement parts for the M1, but the Illinois arsenal rebuilt large numbers of M1s and myriad other arms from 1941 until the late 1950s.

The scope and nature of the rebuild work performed at Rock Island paralleled that of Springfield. M1 rifles and other arms, rebuilt at Rock Island Arsenal, were stamped on the stock with an “ria” stamp over the initials of the foreman of small arms inspection at the arsenal.

The“ria/eb” overhaul stamp signifies the rifle was overhauled at Rock Island Arsenal under the supervision of Elmer Bjerke between 1947 to 1958.


From 1941 to 1946, the stamp was “ria/fk” for Rock Island Arsenal/Frank Krack, who was the foreman during that period. After Krack’s retirement, the stamp was changed to “ria/eb” for Elmer Bjerke who held the position from 1947 to 1958. Therefore, the time frame a particular arm was overhauled can be ascertained.

Other Ordnance Facilities

Other facilities that overhauled M1s, along with other types of arms, during the post-World War II period into the 1950s and 1960s were: Augusta Arsenal (Georgia); San Antonio Arsenal (Texas); Benicia Arsenal (California); Raritan Arsenal (New Jersey); Anniston Arsenal (Alabama); Hawaii Ordnance Depot, Mt. Rainer Ordnance Depot (Washington); and Ogden Arsenal (Utah).

As was the case with Springfield and Rock Island, the arms overhauled by these arsenals and depots were stamped on the stock, usually but not always on the left side, as follows:

Augusta Arsenal—“aa”—Typically with a letter suffix (presumed to be for the inspector supervising overhauls). Later a number suffix (typically four digits) was sometimes added. These markings may be found stamped on either the left or right side of the stock.

Benicia Arsenal—“ba”—Usually consisting of a “ba” over inspector’s initials and enclosed in a box stamped on the left side of the stock.

Hawaii Ordnance Depot—“hod”—Sometimes followed by inspector’s initials. Stamped on left side of stock.

San Antonio Arsenal—“saa”—Usually with a letter prefix. Stamped on left or right side of stock.

Ogden Arsenal—“og”—Often with “e.k.” or “ek” suffix. The “og” or “ogek/o.g.e.k.” stamp may or may not be enclosed in a box. Note: “o.g.e.k.” (enclosed in a box) signified Ogden Arsenal inspector Elmer Keith and “ogek” (not enclosed) signified inspector Ed Klouser. Keith gained fame as a gun writer in the 1940s and 1950s.

Anniston Army Depot (Alabama) used “an”, often followed by a letter suffix, as well as the “a4” stamp.


Anniston Army Depot—“an”—Often followed by a letter suffix.

Mt. Rainier Ordnance Depot—“mr”—Stamped on left side of stock.

Raritan Arsenal—“ra” or “ra-p”—The “p” is presumed to indicate that the rifle was proof fired as part of the overhaul procedure and was not an inspector initial as was the case with the other arsenals. The “ra” should not be confused with the Remington Arms (“ra”) stamp.

Red River Arsenal—“rra”— Later renamed Red River Army Depot—“rrad”—Markings found with and without periods. The 1960s vintage rebuilds usually have a boxed “p” proofmark stamped on the pistol grip.

Later 1960s M1 Rebuilds

As the Vietnam War heated up in the mid 1960s, additional M1s in the government’s inventory were needed as supplemental service rifles and for military foreign aid requirements. Several U.S. government ordnance facilities were given contracts for the overhaul of more M1s during that period. M1 overhaul work in the 1960s was done primarily by Tooele Army Depot (Utah) and Letterkenny Army Depot (Pennsylvania).

The “sa/jlg” stock cartouche represents Col. James L. Guion, commanding officer of Springfield Armory from July 1950 to May 1953. New M1 production and overhauls of earlier M1 rifles both occurred during his tenure.


Red River Army Depot and Springfield Armory also overhauled some M1s into the 1960s as well. Unlike the earlier rebuild markings, which were stamped on the stock, these facilities typically utilized identity codes that were hand-etched on the right side of the receiver leg by electric pen.

In most cases, the code was accompanied by the month and year that the rebuild was performed.
The facilities and codes on the receiver legs were as follows: Letterkenny Army Depot, “lead”; Tooele Army Depot, “te”; Springfield Armory, “sa”; and Red River Arsenal/Red River Army Depot,“rra” or “rrad”. In addition to overhauling M1 rifles in the 1960s, Tooele Army Depot converted a number of M1 rifles to M1D sniper configuration.

Some of the facilities stamped a “p” proofmark on the pistol grip of the stock after the rifles were proof fired as part of the final overhaul inspection procedure. Unlike factory proof stamps which consisted of a circled “p”, the overhaul proof stamps were either a block letter “p” enclosed in a square or by itself.

Rifles that were overhauled at overseas ordnance installations were not required to have the initials of the facility stamped on the stock or engraved in the metal, thus not all rebuilt arms will have overhaul stamps.

The “rrad” stamp indicates overhaul at Red River Army Depot (Texas) in the post World War II period. When named Red River Arsenal, the stocks were stamped “rra”.


It should be mentioned that the presence of an arsenal or depot stamp does not always indicate that the arm was actually overhauled. Some guns in excellent, or even near new condition, were sent to the facilities for inspection, minor repair and cleaning but did not require rebuild. Such arms were usually stamped on the stock to indicate they were cycled through the arsenal or depot but may have been otherwise untouched. This was more common for arms, such as ’03A3 rifles, which didn't require the replacement of many obsolete or superseded parts.

Some M1 rifles in serviceable condition sent to ordnance facilities for inspection may have only had superseded parts replaced, such as rear sights and unmodified operating rods, but otherwise remained primarily in their original factory configuration.

The majority of M1 rifles issued to our troops after World War II had been overhauled at some point. The Ordnance Department was recycling M1 rifles and other arms for many years in order to keep our fighting men armed with serviceable and efficient arms.

An arsenal-overhauled, worn or damaged M1 was rebuilt to the same exacting standards as a rifle just off the assembly line, but at a fraction of the cost. Hundreds of thousands of M1s had their useful life extended by several decades through the efforts and dedication of the skilled ordnance per­sonnel "in the system."

The NRA and the M-1 Garand before WWII

I didn't know that the NRA and the Ordinance dept didn't have a good relationship and the NRA didn't like the Garand and the early Garand had issues with the gas trap.   I have an Garand..or I did if I hadn't lost mine in the great canoe accident recently....It seems to be epidemic....I am in mourning...*sniff* *Sniff*.   I shamelessly clipped this from the NRA online magazine because this has a lot of cool information I didn't know.

At one time, the National Rifle Association really didn’t like the M1 Garand. Shocking, right? This is certainly no longer the case, and I’ll give you a little proof. Back in 2008, we did an article called the “Top 10 Infantry Rifles” of all time. This “Top 10” concept was popular then and now. My staff voted overwhelming for the M1 Garand as the “best infantry rifle of all time.”

John Cantius Garand appeared on the cover of American Rifleman twice, once when his rifle was adopted and again after he retired and received M1 Rifle Serial No. 1,000,000.

I would call John C. Garand a great man, even though he never thought of himself as such. If it were not for him, the defeat of Nazi Germany and Imperial Japan would have cost many more American lives. Simply put, the G.I.s and Marines armed with the “U.S Rifle, Caliber .30, M1” did nothing less than save the world from unspeakable evil.
John Garand shown at his retirement on the cover of American Rifleman in March 1974.

Today, I happily report that the M1 Garand has been on the cover of The American Rifleman more than any other firearm in our entire history. It appeared on the cover when it was first introduced, then again during the war years, then again in rifle competitions. We showed it again with John Garand in his retirement, then again during our coverage of Springfield Armory, again as a go-to collector’s rifle and in multiple instances as a standout piece of history, such as Scott Duff’s article on British Lend-Lease M1 Garands.

So, is it really true that, at one time, American Rifleman editors and the National Rifle Association harshly criticized and had little faith in “greatest battle implement ever devised?” Absolutely, and the story has roots in the development and early years of the rifle itself.

There was a time that John C. Garand was able to say nothing about his rifle, and that started the rift between NRA and the U.S. Army. Back in the mid-1930s, the man at the helm of The American Rifleman was Lawrence Hathaway. Our publication had reported on the U.S. Army Ordnance Department’s evaluations of semi-automatic rifles long before the magazine was even called The American Rifleman, which came about in 1916 after being sold to NRA by James A. Drain for $1.
A rifle design created by Søren Hansen Bang.

In those days, editors and contributors went into incredible detail describing the guns and how they worked for our members. They covered novel designs like the Bang rifle, the Liu rifle, the Mondragon, the Winchester and Remington recoil-operated guns. Army Ordnance and NRA editors were on the same page.

They tested and reported on all these interesting guns for NRA members and the riflemen of the world. All these people had the right to know about these new designs, and the world was curious. Everyone knew that the semi-automatic infantry rifle was the next big thing. The U.S. Army had been looking at every feasible design since 1900.
Several variations of the first Chinese semi-automatic rifle design, as created by General Liu Qing En, first superintendent of Hanyang Arsenal.

Despite the veneration of the U.S. Rifle Model of 1903, the “Cult of the Springfield” I’ll call it—and the U.S. Marine Corps stayed in the cult longer than most—this was the most important stories in rifle development for at least 50 years. Once French chemist Paul Vielle Introduced Poudre B to the world in 1886, it was only a matter of time. A semi-automatic infantry rifle was going to happen for the U.S. Army. But what rifle would they pick, and when would it happen?

At this time, the U.S. Army Ordnance Department and American Rifleman editors were joined at the hip. They were in this together. NRA’s founding mission is about marksmanship and the national defense, after all. We reported on the primer-actuated rifle designed by a young, Canadian-born inventor by the name of Garand back in 1919. The Army gave NRA full access to the rifle and the story. Why? Because they weren’t going to adopt it. That inventor eventually got hired to work at the U.S. Springfield Armory.
The testing of John C. Garand's first primer-actuated rifle.

The U.S. Army had been working on a semi-automatic rifle since before the turn of the 20th century. All of their efforts in testing the Bang and the Liu and every other crazy rifle that every crackpot in the world came up with had been reported in the pages of The American Rifleman. So began the journey to develop a semi-automatic infantry rifle for the U.S. Army.

The Ordnance Department hired the best commercial gun designer available, John D. Pedersen, to work on the concept. Pedersen, a contemporary of John Moses Browning and John Garand, was very good, indeed. Army Ordnance put them on separate design tracks and pitted all these great men against each other. But in the words of the 1980s Movie, “Highlander,” there can only be one. That one was the “U.S. Semiautomatic Rifle, Caliber, 30 M1.”
The toggle-lock action of Pedersen's .276-cal. rifle shown locked open.

Really, the United States was the only country in the world that was capable of developing and mass-producing the M1 rifle. It was a country that had the willpower and the patience to develop the M1. The American Rifleman reported on it. This was big news. The biggest news.

But when we look at the first article about the M1 rifle, there are some clues as to the emerging rift. The author, Col. Drewry, was not on the magazine staff. He didn’t test guns for NRA members. He was an Army Ordnance officer.

How did this happen? Well, the story was not written for The American Rifleman. It was written for the Infantry Journal. The American Rifleman was merely allowed to run it. It must have chapped Editor Hathaway’s bunions to no end.

Back then, the most comprehensive evaluations of firearms in the world happened in the pages of The American Rifleman. If you made a gun, you sent us a gun. We shoot it, we tear it down, we describe every bit and piece, how it’s made and how it performs. We shoot it, and the gun does what it does.
Examples of the comprehensive testing performed by American Rifleman staffers in the early 20th century.

But in this instance, the Army wasn't talking. Fred C. Ness, American Rifleman technical editor, did not receive a “U.S. Semiautomatic Rifle, Caliber .30,” at the Barr Building or later at 1600 Rhode Island Avenue. They didn't let him take it apart and describe every feature. They didn't even brief him about it. The American Rifleman got the Army official story from Col. Drewry.

Meanwhile, there was a man named Julian S. Hatcher. He graduated from the U.S. Naval Academy and was commissioned as a lieutenant in the U.S. Army Ordnance Corps. He started contributing to The American Rifleman early and often. He answered questions from NRA members, he described guns, ballistics, loads and bullet performance. Again, Army Ordnance and The American Rifleman were joined at the hip through Hatcher.
The lead story page as written by U.S. Army Ordnance's Col. Drewry.

Once the US Army adopted the U.S. Semiautomatic Rifle, Caliber .30 M1, in 1936, though, that all changed. Then-Major Julian S. Hatcher went silent. His brother, Major James Hatcher, was running the M1 rifle’s development. Julian Hatcher, who would later become technical editor of The American Rifleman, answered question about knockdown power and cast bullets, but not about the M1 rifle. In the pages of the magazine, as far as the M1 was concerned, Julian Hatcher went dark.

Hatcher was the one guy who regularly answered member letters in the pages of The American Rifleman, and he worked with John C. Garand in the 1920s. He would go on to write the Book of the Garand. He and Garand were friends. They shot in the Springfield Armory weekly pistol league together. Hatcher’s Colt Camp Perry is in the NRA Museum. I have a Christmas card from Major and Mrs. Julian Hatcher to Mr. and Mrs. John C. Garand. They were friends and worked together toward, arguably, the most-important American rifle of all time.
Then-Captain Julian Sommerville Hatcher shown with a semi-automatic rifle of his own design.

From 1935 to 1939, I know for a fact that Hatcher’s name appeared 158 times in 94 different NRA documents and publications. After the adoption of the M1, not a word written by him was about the M1.

The M1 Garand was adopted officially in 1936, and there is scant information about the rifle in the pages of the magazine. Snippets, but nothing substantive. It must have been incredibly hard on the editors, who were itching to understand and share this revolutionary new rifle design with NRA members.

Later, Camp Perry was blessed with a demonstration of the M1 rifle. Army Ordnance brought it, it shot, but not very well, and ordnance officials would not let NRA’s representative fieldstrip the rifle. They wouldn’t let our technical staff look inside the rifle. Even though that’s what The American Rifleman staff did and that’s what they had worked hand-in-hand with Army Ordnance on for decades at this point, the Army stopped them from taking a peek anyway.

The Army Ordnance Department’s secretiveness and their unwillingness to pull the trigger guard down and let NRA see inside the M1 led to congressional hearings, sensationalist national news stories and a feeling that the Army was hiding something about its new rifle. The Army’s reticence to share information about the M1 opened a door. A door that Melvin Maynard Johnson drove a truck through.

While development of the Garand had occurred, Johnson had worked on a separate rifle design. When the U.S. Army hid the M1 Garand from the NRA, Johnson was open and forthright about his new gun. Ness made Johnson and his rifle a national news story. His rifle had some features the M1 did not, being able to top off a magazine and a 10-round magazine capacity, for example. Since the Army hadn’t adopted his rifle, Johnson could let NRA take it apart and describe every piece.
Melvin Maynard Johnson shown here with several of his early rifle designs.

The Army and NRA were in pretty much open conflict about the M1, and there were snarky reports throughout this period that illustrate this war of words. U.S. Army Ordnance even went so far as to run advertisements discussing the Army’s new M1 rifle in other magazines of the period, but not The American Rifleman.

Then came Camp Perry. At the Small Arms Firing School at Camp Perry that year, the Army once again demonstrated the M1 rifle. Attendees were allowed to fire the rifle, but NRA staff was prohibited from taking the gun apart. Ever heard of waving a red flag at a bull?
Page one of six of Ness' article on the "revolutionary" Johnson rifle.

The flame stoked by the Army’s lack of cooperation led to a lot of public debate. It led to editorials from newspapers that couldn't tell an M1 rifle from a badminton racket. It led to congressional hearings, hearings in which senators and congressmen made the Army a little uncomfortable.

Meanwhile, NRA’s promotion of the Johnson rifle no doubt helped it go from prototype to production to limited service with the United States Marine Corps. If you ever want to find fans of Melvin Maynard Johnson designs, look no further than the “Super Commandos”—the Canadian and American troops that formed the U.S. Special Service Force. The “black devils” loved their “Johnny guns.”

It’s true that the Johnson rifle did have some good points, but F.C. Ness highlighted it more than was probably necessary, which only goes to show that there was a deeper purpose to the whole thing. In one article, Ness spent six pages describing the Johnson rifle in prototype form.
Due to the attention paid to it by American Rifleman editors, the Johnson Rifle gained traction and saw limited military service.

For contrast, another new gun appeared in 1936 that some might recognize: the Winchester Model 70. Yes, the “Rifleman’s Rifle.” The American Rifleman editors devoted far less space to this iconic design than they gave to the Johnson rifle.

Meanwhile, the Army still would not let NRA see inside an M1. The Army knew it had a problem with the gas trap, but it wasn’t going to admit it to anyone and certainly not to the NRA. There was a reason for that that extended beyond Ordnance department pride. From 1936 to 1940, the M1 was not perfect. It was not the gun that would win World War II.

In 1940, the Army decided to switch from the gas trap to the gas port and, in November of that year, made a change it didn’t talk about. That change was the drilling of a hole in the barrel and the elimination the unreliable gas trap. The gas-trap system worked better than most full-power semi-automatic military rifles, but it didn't work well enough.

It’s important to recognize that, in 1940, it was a very different world. No Army anywhere had a adopted a semi-automatic design as its standard service rifle, The French, the Soviets, the Germans and even the British had experimented. Some even adopted them but never for general issue.

All the secretiveness and lack of cooperation made it look as if the Army was hiding something about the M1 rifle. As it turns out, the Army was, and there were problems beyond the gas-trap issue. As the prototype rifles turned into production rifles, things begin to vex engineers at Springfield Armory.

The best known of these issues is the seventh-round stoppage. As most folks know, you can stick an M1 en-bloc clip in either way. Ordnance engineers found that if the top cartridge was on the right, then the seventh cartridge would also be on the right. This round would jump up out of position and jam the bullet nose into the receiver.

At the 1939 National matches at Camp Perry, Lt. Col. James L. Hatcher was doing a demonstration with the M1 Garand. The seventh-round stoppage hadn't been solved yet, so he and Capt. Rothwell Brown made sure that all the clips were loaded with a seventh round on the left. The demonstration went well, but as Julian S. Hatcher wrote in the Book of the Garand, “a feeling arose that all is not well.”

Hatcher continued: "At the demonstrations at Camp Perry, civilians were invited to fire the rifle, but there's always an Army man at the shooter’s elbow ready to snatch the rifle away and perform some sleight of hand at the slightest sign of a malfunction … . Moreover, the members of the NRA staff, to their surprise, found that they were unwelcome whenever they approached a Garand or wanted to fire it."
Julian S. Hatcher would later become technical editor of American Rifleman.

There were other issues. The jumping clip, the sticking operating rod cam, rear sight trouble, and of course, the M1 needed a new gas cylinder. By October 1939, the so-called gas port gas cylinder assembly, with a hole in the barrel, was recommended and adopted. Gas-port rifles started production early in 1940.

In May 1940, F.C. Ness of The American Rifleman obtained an M1 rifle and a single eight-round en-bloc clip. As a gun writer for the past 29 years, I know when a writer is out to get a gun. And F.C. Ness was out to get the M1 rifle. But the rifle he received was not the new gas-port M1 Garand. It was the older “gas-trap” gun that clearly had issues.
The U.S. Army Ordnance drawing supplied with Col. Drewry's first article.

What's interesting is that, while reporting every stoppage, including those that occurred when single-loading, and criticizing the design, he did note that this was not the new “gas-port” system. Ness knew about the coming gas-port system that would make the M1 Garand into the reliable battle arm everyone knows today, but he chose to concentrate on the faults of the “gas-trap” Garand.

There's another aspect to all this that we can recognize today. It’s reasonable to assume that the Germans read The American Rifleman magazine at the time. If I had been a potential enemy of the United States, I sure would have, knowing how much information about U.S. Army Ordnance testing ended up in the pages of the magazine.

What if supplying F.C. Ness with a gas-trap model in February 1940 was the plan? What if the Army knew of Germany’s interest in the M1 rifle? What if they deliberately planted misinformation by giving F.C. Ness a gas-trap gun after the Army had already switched over to gas-port Garands?
U.S. Army Ordnance-supplied schematics of the M1 Garand.

Another interesting piece of information was the reporting of the number of M1 rifles being produced. In May 1940, it is said there are fewer than 25,000 guns. Only about 4,000 a month were reported.

No one involved is still alive, but this looks to me like the Army was trying to tell the Germans that the M1 wasn't ready for prime time in terms of the effectiveness of the rifle or the numbers produced. This is all pure speculation on my part, though still worth thinking about.

What is in the record is what Julian Hatcher thought about the secretive nature of the M1 rifle’s development and what possibly could have happened:

“Had the association been kept fully and frankly informed about the rifle, they could have been counted on by the War Department both for informed and constructive criticism and suggestions, and also for powerful support of any decisions reached as a result of Army needs and experience."
John Garand's early prototype of the M1 Rifle shown in 1930.

NRA’s leadership was comprised mostly of Army and National Guard officers. These were officers like Gen. Milton A Reckord, Adjutant General of the Maryland National Guard—who would eventually command the 29th Infantry Division during World War II. Think you could trust him? I do.

But as it stands, the first army in the world to declare a semi-automatic rifle as its standard-issue arm was the United States Army, and the M1 rifle became of the greatest military secrets of the age. How did America do it? Well, Nazi Germany wanted to find out.

The secret of the M1 Garand certainly wasn’t on the level of the later Manhattan Project, but our enemies still wanted all the information they could get. German spies sought out the plans to the M1 rifle. Members of the Duquesne Spy Ring actually obtained the plans for the M1—the FBI even filmed one Nazi spy pulling the schematics out of his sock in New York before the United States ever entered World War II.
Nazi spy Frederick "Fritz" Joubert Duquesne pictured after his capture by the FBI.

Even though these Nazi spies were arrested, I think it is logical to assume Nazi Germany got the plans to the M1 Garand. After all, they found the plans for the Norden Bombsight. But the designs they obtained were not of the M1 Garand as we know it, the Garand that entered the battlefield in huge numbers during WWII. I believe they got plans to the gas-trap variant.

In late 1940, the German Ordnance Department solicited a semi-automatic rifle from Walther and Mauser for adoption in 1941. One of the requirements was that they could not drill a hole in the barrel. Why would they include such a specific requirement? I would argue that they may have had plans for the M1 rifle that did not have hole in the barrel. Both the Mauser G41(M) and the Walther G41(W) had goofy forms of gas-trap operation. Neither worked very well.
The German Gewehr 41, which used a gas-trap operating system rather than a gas port.

Early M1 Garands may have gotten into German intelligence hands from their Japanese allies following the fall of the Philippines, but the guns captured there would have been a mix of gas-trap and gas-port rifles. The Germans eventually drilled a hole in the barrel and came up with G43 rifle. The Japanese also copied the gas-port M1, and they came up with the Type 5.

Before the capture of these issued M1 Garands in the Philippines, the one thing that German ordnance seemed pretty serious about was that neither entrant, Walther or Mauser, was to drill a hole in the barrel. What they ended up getting was the G41(W) and the G41(M). Both rifles were frail and finicky, but neither of them had a hole in the barrel.
The Japanese Type 5 was copied later and featured the same gas-port system as later M1 Garands.

At that time, as far as the world knew, the U.S. Rifle, Caliber .30 M1 didn't have a hole in the barrel. The only scant mention of a gas-port model was in Ness’ May 1940 article in The American Rifleman. The only country in the world that ever figured out a reliable semi-automatic rifle concept was the United States. When the Germans went to develop their own, it is my supposition that they went with what they knew worked. That was the M1 Garand.

By the time that specification went out in 1940, there were no M1 rifles outside of the U.S. government. Sure, some were sent to England under the Lend-Lease Act. Some were sent to the Philippines. As a matter fact, the M1 rifle's introduction to combat came during the fighting for the Philippines in 1942. Despite being mostly gas-trap rifles, from everything we can tell, the M1 performed pretty well.
A May 1941 issue of American Rifleman shows that NRA and the U.S. Army had reconciled.

With improvements, though, the M1 rifle would perform even better. It would go on to be the rifle in the hands of young men who went overseas, fought and died so that the flame of freedom would not be extinguished. The rifle that went to North Africa, the rifle that went to Guadalcanal, to Monte Cassino, to Omaha beach, to Tarawa and Iwo Jima, wasn't the same rifle that the Germans tried to copy. It was not the same rifle that the army hid from the NRA. It was better.

In the interim, NRA got over its concerns about the M1 rifle. After Dec. 7, 1941, the NRA was all-in following the “day that will live in infamy.” NRA and its members went on to train millions of young Americans in marksmanship during pre-induction training programs.

We wrote manuals on marksmanship. We even did a “how-to” guide for plant and industrial guards. Our members served both at home and overseas. A generation of young Americans armed with M1 Garands did nothing less than save the world—one eight-round en bloc clip at a time.
