Patent ID: 8387295

Claim:
A handgun having a device for ascertaining the shot count, which has electronics having a microprocessor and a memory which may be read out, a power supply, and a sensor for delivering a count pulse to the memory when a shot is delivered, the sensor being an acceleration sensor detecting the acceleration of the firearm, reference values for the intensity curve of the acceleration measured by the acceleration sensor upon firing of the firearm being stored in the memory, and said microprocessor being designed in such a way that said microprocessor outputs a count pulse to the memory in the event of positive comparison of an intensity curve of the acceleration measured using the acceleration sensor to the reference values stored in the memory, comprising the improvement wherein the acceleration sensor detects the acceleration of the firearm in all three spatial directions and a further sensor is provided, which outputs a signal to the microprocessor upon picking up the recoil impulse upon firing, the further sensor being a piezoelectric sensor, and wherein the reference values for the intensity curve of the signal of the piezoelectric sensor upon firing the weapon are stored in the memory and the microprocessor is designed in such a way that said microprocessor outputs a count pulse to the memory in the event of positive comparison of a signal output by the piezoelectric sensor to reference values stored in the memory for the piezoelectric sensor.
