Abstract: A drive assembly of a firearm includes a hammer, a firing pin, a trigger and drive means for driving the firing pin. The hammer includes a main body having at least a first tooth, a first seat engaged by the firing pin and a second seat engaged by the drive means that intercepts the first seat. The firing pin and the drive means are movable in the respective seats between a first rest portion, distal one from another, and a second firing position, respectively, proximal one to another. The trigger includes a first portion that, when the trigger is pivoted, it is movable between the first and second positions, respectively. The trigger includes a second portion configured to engage/disengage the first tooth and a third portion configured to counter the drive means when the first portion of the trigger is in the second position and the first tooth is disengaged.

Abstract: A pump gun is disclosed having a loading and firing mechanism which comprises a cartridge stop lever (21), that is not connected to the hammer, interacts with the cocking slide (22) associated with the cartridge magazine and is susceptible to rocking movements on an intermediate pin (30) between an operating interception position of a first cartridge in the magazine, when the cocking slide is in a retracted work position, and an idle release position of the same cartridge from the magazine tube, when the cocking slide is in the forward rest position.

Abstract: The present invention concerns a safety device for a firearm such as a revolver, which includes a flexible, elastic element (24) fixed to the hammer and having a free end (26) interacting with the tail of a cylinder blocking lever (13) to move the latter from an active block position to an inactive release position of the cylinder consequent to a rotation of the hammer from a rest position to a cocked position passing through an intermediate, safety half-cocked position.

Abstract: The invention relates a safety device on the hammer for revolvers which comprises a safety slide (20) guided in a seat (22) formed in the frame (11) of revolver, laterally to the hammer (12) and having a blocking tooth (21) transversely extending between the breech (11') of the frame and the front face (12') of the hammer. The safety slide is movable up and down, to an active upper position and an inactive lower position, and an entraining pin (25) located on the hammer interacts with the safety slide to move it in the inactive lower position when the hammer turns from the armed position to the percussion position.
