The upper barrel (6) is longer than the lower barrel (7). Guide protrusions (8) are provided on the unit (5) of the two barrels (6, 7), which guide protrusions are guided in corresponding control tracks (9, 10) in the housing (1), whereby the two barrels (6, 7) can be moved along the control tracks (9, 10) between two end positions, wherein, when each end position is reached, alternately one of the two barrels (6, 7) aligns with the cartridge feed (2) and therefore forms the active barrel, which can be locked in this position.
