An improved semi-automatic shotgun of the type contains a magazine tube (8) around which is provided a cylinder (9) whose interior part communicates with an interior part of a barrel (2) of the invention. In this cylinder (9) and around the magazine tube (8), a piston (10) can be shifted by propulsion gases. The piston cooperates with a sleeve (12) provided with a rod (13) which can act upon the whole of the moving parts (14) on the one hand, and a control or pressure control valve (11) on the other hand is situated in the piston block (10).

Fire arm

Firing mechanism for fire arms, includes a hammer (5) revolving between a 'cocked' position and a 'tumbled' position which makes contact with the striker (4), a tumbler (8) which can retain the hammer (5) in the cocked position, a trigger (13) which controls the tumbler (8), an assembly (20) to make the hammer (5) revolve from its cocked position towards the striker (4) of the arm when the hammer (5) is released by the tumbler (8), and a security device containing a bolt element (27) which can be manually locked and which can lock the trigger (13). The bolt element (27), in the security position, not only cooperates with the trigger (13), but simultaneously with the assembly (20) to make the hammer revolve in order to prevent the hammer (5) from knocking against the striker (4) as long as the bolt element (27) is in its security position.
