Abstract: Device for detecting and counting shots fired by an automatic or semi-automatic fire arm with a barrel and moving parts to recock the fire arm, sliding in the axial direction (Y-Y?) of the barrel between a front position and a rear position, whereby the fire arm undergoes accelerations in the axial direction (Y-Y?) of the barrel for every fired shot, caused by a succession of shocks due to the shot being fired and to the movements of the moving parts, whereby the progression in time of the accelerations is typical for a fire arm and for the type of ammunition used, thus forming a typical signature for the fire arm and for the type of ammunition, characterized in that it comprises an accelerometer (2) with a pass band which is sensitive to shocks in the axial direction (Y-Y?) of the barrel and a microprocessor (3) for analyzing the signal (S) of the accelerometer (2) while firing, whereby the microprocessor (3) is equipped with an algorithm to count the number of shots fired, based on the discernment and recor

Abstract: Firing device includes a firearm which includes a cartridge carrier in the loader in front of the entry of the barrel and supported against a supporting element of the casing which includes the firing mechanism and whereby the barrel slides in the casing into a position in which the barrel comes to a stop through the action of a return spring against the front part of the case of the cartridges and wherein each cartridge is provided with propulsion arrangement to project the case and the barrel forward.
