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.

Claim (Index 5):
The breech catch mechanism according to  claim 1 , wherein a rotary attachment of the two longitudinal rails to the pistol body or to the inserted container is implemented by means of an opening provided at the end of the two longitudinal rails and a pivot that is a part of the pistol body or of the inserted container.
