Abstract: 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.
