After being lightly struck by the Mexican's gun, Mason is sent sent flying as if he was pistol whipped. He was lightly hit under the chin after the gun was held to his temple. This may have hurt but would not have sent him flying and not likely result in a cut to the forehead.

After being pistol whipped, Mason is picked up by a helicopter. In the next scene two helicopters are turning away from a military plane in flight and on which Mason is a passenger.
