Claims (1)

GERMAN We already know 'shooting bolts for use in solid material by means of a pistol, which are provided with a collar, through which they can before and during When the shot is fired, it must be held in the base of the pistol until the explosion pressure has reached a certain value. With some shooting bolts, the collar will tear off as soon as the gas pressure has reached a certain limit exceeds, and remains after the firing bolt has been fired back in the bottom piece. This is extremely annoying, as the collar comes out after each shot The bottom piece has to be removed with a tool or with your fingers, which is often tedious, always but it is a waste of time. With other firing bolts, the collar is not torn off, but bent backwards. Since the Guide of the firing bolt in the barrel in general takes place through the bent collar, this must be plentiful for proper guidance be measured. The seal created between the firing pin and the barrel leaves both of them often enough left, SO 'that to achieve a sufficient bolt speed, the drive set is chosen to be relatively large must become. The invention is intended to avoid these deficiencies. To this end, the invention provides a firing pin with a Führungsghüls.e, which has an annular extension through which the Bolt is held in the gun until the explosion pressure has reached a sufficient value, an annular extension of such small dimensions before that this is flattened when the projectile movement begins. This is how it arises on the one hand, a perfectly tight seal between the courtship and the barrel of the pistol, while on the other hand the cylindrical part of the sleeve takes over the guidance of the firing pin in the barrel. Mounted guide sleeves for shooting bolts are well known per se, but these sleeves have no ring-shaped approach designed according to the invention, so that with these known sleeves not the above-described advantageous effects peculiar to the embodiment according to the invention can be achieved. An exemplary embodiment of the invention is shown in the drawing. The firing pin shown consists of a pointed steel body i, the head of which can have a thread 2, and the firing pin provided with a bucket-slotted guide sleeve 3 made of soft metal
