Abstract

The invention relates to a self-loading hand firearm with a barrel (7) secured to a frame (1), a firing pin, a slide (2), and a closure (3) which is held, in the front position of the slide (2), in a locking position on the frame (1) and which is moved from the locking position into a release position by gas pressure of a fired projectile. According to the invention, the closure (3) is formed at least in two parts with a closure locking mechanism (4), which has two lateral legs (8, 9), and a closure impact base (5) lying between the legs (8, 9), the closure locking mechanism (4) being provided at the legs (8, 9) with at least one protruding driver element (22), which is designed to engage in a recess (23) of the slide (2), and with at least one retaining cam (24, 25), which is designed for engagement in a shoulder (26) of the frame (1). The closure impact base (5) and the closure locking mechanism (4) are hinged to one another.

Abstract

An automatic pistol essentially consists of an immovable barrel, a breech with a firing pin and a cartridge extractor, a breech frame, a spring-loaded device for the removal of gas with a gas piston and a gas cylinder, a firing mechanism and a magazine. The barrel is fitted with an end piece, which is located in the lower part of the rear end of the barrel. The design of the breech allows for the displacement of its front part downwards, when the breech is in its front end position. The front part of the breech is fitted with side locking lugs. The corresponding locking grooves are located in the cavities on the end piece of the barrel. The gas piston has an opening for ejecting the cartridge casing. In the course of the backward movement, the gas piston unlocks the breech and draws it back. In the forward movement, the breech is carried forward and pushed downwards. The gas cylinder is located at the front part of the barrel and encompasses the barrel. Along the length of the barrel gas ducts are fixed.
