<p>A self-loading firearm operating on the short-recoil principle which comprises a frame (1) having a handgrip (2) and adapted to receive a magazine. A breech block slide (3) is mounted for alternating longitudinal movement along the frame (1). A barrel (4) is provided which is able to move rearwards while positively locked with the slide member (3) by locking means (9 and 6). An actuating means (15 and 8) disengages the barrel (4) from the slide (3) after the high pressure period has passed. An expandable chamber means (11 and 10) is fixed to the underside of the barrel (4) which communicates with the barrel bore (10) via a passage (13). The action of the expandable chamber means (11 and 10) retards the motion of the barrel (4) and slide (3) assembly allowing a lighter slide (3) to be used for a specific cartridge type.</p> |
