摘要： The invention relates to a device opening and closing the bolt of semiautomatic pistols with a barrel (11) wich is rotating and axially displaceable in the stock (10) and interacting with the bolt (12) in such a way that during the first section of the back motion barrel (11) and bolt (12) are integral and without a relative motion, while in the second section the barrel (11) rotates in respect to the bolt (12) but is still following its linear movement till the barrel (11) stops and the bolt (12) moves back for the actual opening of the arm.

摘要： A firearm according to this invention has a bed (21) formed in the front part of a frame (2) in which is crosswise situated a pin (22). In the rear part of a barrel (3) there is formed a recess (31) of a helical form having on its opposed side ground off unlocking recess (32). The barrel (3) can rotate round its longitudinal axis due to a recoil resulting in unlocking the barrel (3) and a bolt element (4). The firearm (1) has as a trigger (51) with independently from each other suspended single-shot draw bar (52) with a single-shot protrusion (53) engaging into a single-shot groove (42) and a double-shot draw bar (58) with a double-shot protrusion (59), engaging into a double-shot groove (43), the protrusions of which lean against the bottom surface of the bolt element (4). The double-shot mode of a firearm (1) is put out of operation by means of a safety catch situated in the frame (2). A locking catch is formed in one pressed piece of sheet metal.

摘要： A pistol includes a cross-sectionally U-shaped frame (1) which has first and second opposite side walls, a formed-on grip, a formed-on trigger guard (5), a first through bore provided in the first side wall and a second through bore provided in the second side wall in alignment with the first through bore. A structural unit (10) is removably accommodated in the frame above the trigger guard and includes bilateral guide rails and a through aperture aligned with the first and second through bores. The structural unit is received in the frame with a form fit for preventing longitudinal displacements of the structural unit relative to the frame. A removable pin (16) passes through the first and second through bores and the through aperture in the structural unit for removably securing the structural unit to the frame.
