The trigger bar (7) is arranged in the pistol frame on a cross pin (29) that crosses the vertical surface (7m). The trigger bar (7) is moveable by means of a trigger (15). In the pistol frame, over the trigger bar (7), a disassembling lever (11) is arranged that has a button (11d) and a pivot (11a) that carries a cam (18) for engagement with the trigger bar (7).
