An automatic pistol (10) for repetitively firing blank ammunition includes a frame (102), a barrel unit (118) including a barrel cha mber portion and a barrel element extending from the barrel chamber portion, and a slide (106) mounted on the frame (102) and reciprocall y longitudinally moveable relative to the frame (102) between a forward batter y position where the pistol is capable of firing and a r earward position where a spent blank cartridge is ejected. The slide (106) is initia lly freely moveable relative to the barrel unit (118) to an engaging position of the slide (106) displaced from the forward battery position. At the engaging position, the slide (106) engages an abutme nt surface (120) of the barrel unit (118) thereby moving the barrel unit (118) to a position where the barrel chamber portion receives a blank cartridge. A mechanism, i.e., a restrictor element (124), may be provided fo r generating sufficient back pressure in the barrel unit (118) upon firing of a blank cartridge to move the slide (14) to the rearward posi tion.
