ABSTRACT:
An automatic hand firearm for ammunition with extremely high projectile momentum is designed as a recoil loader which has a mounted barrel, supported by a spring and brake system (6, 7) on the weapon housing, a breech block (9, 10), which can be rigidly locked with the barrel and which encompasses a breech block carrier (9), movably led in the weapon housing (2) and supported on a breech-closing spring, and also encompasses a plug (10) which is longitudinally adjustable in relation to the breech block carrier, which carries locking parts (14) which can be engaged or disengaged with locking parts (15) on the barrel (1), and having devices comprising cams (18) and follow-up parts (17) for engaging-and-disengaging locking parts (14, 15) with the counterrecoil and recoil motion of the breech and with which the device for disengaging the locking parts (14, 15), arranged on the barrel (1) and on the plug (10), with the recoil motion of the breech block, is arranged between breech block carrier (9) and plug (10). If weaker ammunition is also to be fired with the same weapon, the loading process can be supported by an additional gas-operated-loading-device.
