Pistol with firing mechanism that can easily be adapted to various modes of operation

A pistol with firing device easily adaptable to various kinds of operation, comprising a wrist over which a latch is moved, said wrist comprising a butt, inside which a comb, a trigger guard involving a trigger and a metal back support, intended to lodge part of the components of the pistol firing device, are lodged, wherein said firing device comprises said trigger, hinged in pivot to a first edge of the rod, said opposed end of said rod is located on the back support, said latch involves and lodges the percussor, located behind and aligned to the chamber wherein the cartridge is located, and said latch has, around its front portion, the spring of the percussor, acting over the backstop and, on its back portion, a tongue projecting downwards, said pistol further comprising:

• a rod, in the shape of a formed laminar element and including, on said edge in opposition to the trigger, a stick and a crosswise arm, wherein said crosswise arm is projected from the lengthwise body of the rod, towards the central portion of the pistol and has a front surface, able to mechanically interfere with said tongue, and a wing, frontal to the crosswise arm and projecting downwards, in which central region there is an oblong opening;
• a guiding pin of the latch, fixed to the back support and with its lengthwise beam in parallel to the length of the pistol, wherein said guiding pin of the rod crosses the oblong opening of the wing of the crosswise arm, so to limit the upwards and downwards movement of said crosswise arm;
• and
• a rod ramp in the form of an elongated laminar body, fixed at a lower edge to a crosswise beam and, on the opposed upper edge, having a fold turned outside over the center of the pistol, thus defining a contact surface mechanically working against the stick of the rod.
