Abstract: The proposed invention relates to small arms, specifically to charging devices for charging magazines with cartridges and to meters for cartridges in box magazines. The technical result consists in providing a universal charging device and meter for cartridges in box magazines which makes it possible to achieve rapid charging and discharging of cartridges to and from said magazines and visual and tactile monitoring of the number of said cartridges in box magazines which have been withdrawn from and inserted in a weapon. The device has a minimal weight and can easily be built into any box magazine of an automatic machine gun or a pistol having a spring-loaded cartridge feed mechanism.

Abstract: An automatic handgun has an additional trigger mechanism and a sight. In one version, a draw bar in the butt is hinged to a rotatable fork and to the additional trigger, located on the left of the butt in an L-shaped groove. Upon rotating the fork the spring extends onto the left of the butt, and when the butt is closed onto a catch, the end of the fork grips the main trigger. Rotatable posts lie on the sight. Alternatively, a rotatable lever sits on the lower front of the breech. The lever has a post on which the additional trigger which fixes the horizontal and vertical positions is hinged, and is connected to the main trigger by a draw bar through the inside left of the breech. Shooting accuracy increases and the overall dimensions are reduced.
