<p>A basic device for a pistol (1), intended to work in the DAO mode of operation and easily adaptable to other operation modes, is disclosed. The pistol especially comprises a rod (14), including, in said edge opposed to the trigger (5), a stick (16) and a crosswise arm (17), wherein said crosswise arm (17) is projected from the lengthwise body of the rod (14), towards the central portion of the pistol (1, 40, 50), and includes a front surface (18), able to mechanically interfere with said tongue (24), and a wing (19), frontal to the crosswise arm (17) and projecting downwards, in which middle region an oblong opening (20) is included; a guiding pin for the rod (21), with its lengthwise beam parallel to the length of the pistol (1, 49, 50), wherein said guiding pin of the rod (21) crosses the oblong opening (20) of the wing (19) of the crosswise arm (17), so to limit the movement of said crosswise arm (17) upwards and downwards; and a rod ramp (30), in the shape of an oblong laminar body, fixed to a lower edge on a crosswise beam (22) and having a fold in the opposed and upper edge, turned outside over the center of the pistol (1, 40, 50), to define a contact surface mechanically acting against the stick (16) of the rod (14). The pistol (40) for actuation in SA mode also includes a bush (42), in the form of a cylinder with a central hole and located around the guiding pin of the rod (21), so to limit the path forwards of said rod (14); and a rod ramp (30') comprising a disconnecting arm (43), able to mechanically interfere with a rib (45) of the latch (6), so to displace said rod ramp (30') to inside the pistol (40). On the other hand, the pistol (50) for actuation in DA/SA mode includes, besides the rod ramp (30'), a rod lock (51), in the form of a hinge and defining: a lower portion (54) having an external surface able to be activated by a key, as well as a spring (55), so to constantly push said lower portion (54) outside, and an upper portion (56) comprising an arm (57) which extends in parallel to the beam (53) of the rod latch (51), as well as a head (58) located on the upper edge of said rod latch (51); and a restraint (52), basically in the form of a cube, assembled over the guiding pin of the rod (21) in a position between the wing (19) of the crosswise arm (17) of the rod (14) and the spring (59) located around the guiding pin of the rod (21).</p> |
