Abstract: A pistol comprising a barrel having a combustion chamber and slide translatable between an advanced configuration closing the combustion chamber, and a retracted configuration opening the chamber and in both configurations is substantially parallel to a longitudinal axis. The slide has a locking seat and longitudinal grooving. A closing organ rotatable with respect to the axis between a first and a second angular position and an element drawing in rotation the closing organ and fixed to the fore-end. The closing organ has a locking relief and a cam taking the rotation from the at least one element drawing in rotation.
