The barrel of an automatic hand weapon is held stationary in a weapon housing in which an axial symmetrical bore is formed perpendicularly to the barrel axis. A cylinder-shaped cartridge chamber housing (10) is disposed within the bore and is movable by positive intermittent rotary movement in the same direction about its axis of rotation into a firing position and a loading position. In order to permit improved matching with the ammunition especially with an uncased cartridge and to permit, if necessary, the provision of an obturator at the projectile-side end of the cartridge chamber and optionally to increase the firing cadence, two cartridge chambers (12, 14) are formed in the housing. These are mutually disposed centro-symmetrically relative to the rotational axis of the housing. For firing uncased ammunition, plungers (31, 32) are used, plunger (32) separating the projectile (3) from the propellant charge (2).
