A pistol includes a carriage which receives a barrel. The carriage slides back on a handle of the pistol during discharge against the force of a return spring. The pistol includes a device for determining the number of shots fired. The device includes electronics attached to the handle and including a microprocessor with storage, a piezoelectric sensor connected to the microprocessor, a current supply, and a reading device for reading the storage, which reading device is external to the pistol. The piezoelectric sensor receives recoil impulses during discharge and sends a signal to the microprocessor in response to the impulses. The microprocessor is connected to a second sensor, which sends a second signal to the microprocessor when the carriage slides back. The microprocessor sends a count impulse to the storage during a time interval between the first signal of the piezoelectric sensor and the second signal, which corresponds to the time interval between discharge and sliding back of the carriage during a discharge.
