In a hammerless automatic pistol with double-action and single-action functions there are provided between the trigger arm and firing pin of the trigger mechanism a catch pawl for the firing pin and a support lever that maintains the catch pawl in the catch position. During double-action operation, both of these intermediate components are disengaged but they are engaged for single-action function. The engagement and disengagement of these intermediate components is performed automatically during the shooting cycle. By merely removing one or both of these intermediate components the automatic pistol can be modified for double-action only trigger function, in which the firing pin is simultaneously cocked and released for firing during each shot by actuating the trigger.

Trigger mechanism for firearms

A barrel retaining device for an automatic pistol has a locking element that locks the pistol barrel and breech both of which are guided on the stock of the weapon. In order to remove the breech with the barrel from the stock in order to disassemble the pistol, the locking element has an actuating element on both sides of the stock which, when depressed, unlocks a lock between the barrel and the stock. At the same time, depressing of the actuation element releases the trigger finger into a forward position to impart a forward movement to a spring loaded trigger arm which is also cammed downwardly to disengage the trigger arm and the driver on the firing pin in the breech. The connections between the breech and the stock are thus released by a single unlocking movement when disassembling a pistol.

Barrel retaining device for firearms

A magazine retainer that is actuable on both sides of an automatic pistol is mounted to pivot in a recess of the stock of the pistol. The recess or the magazine retainer is molded during the injection molding of the stock. The magazine retainer is provided with two lateral actuation plates which are positioned in openings on both sides of the rear portion of the trigger guard and these trigger guard openings have a depth which corresponds to the thickness of the actuation plates. Accordingly, the outer surfaces of the actuation plates conform smoothly with the outer surface of the firearm and there are no projecting portions thereof in the area where the trigger guard merges with the pistol stock.
