Abstract:
A breech catch mechanism for automatic and semi-automatic pistols includes a catch ( 502 ) of a breech comprising two longitudinal rails ( 400, 401 ) that are attached to pistol body or to an inserted container at one end in a rotary way and at the other end they are connected with a bridge ( 402 ). One of the rails ( 400, 401 ) is provided with an internal projection ( 405 ) protruding into a space between the rails ( 400, 401 ). The mechanism further includes the breech provided with a feeding bridge ( 250 ) and a cartridge feeder ( 500 ) positioned under the internal projection ( 405 ) and configured to push, after feeding of the last cartridge, from below against the internal projection ( 405 ), thus tilting the breech catch ( 502 ) from its basic position upward to an upper position in which the breech leans with its feeding bridge ( 250 ) against an outer surface ( 408 ) of the bridge ( 402 ) of the catch ( 502 ) of the breech to lock the breech in the rear position.
