Abstract: A firearm training system is disclosed, which allows the measurement and display as a function of time of the hand grip force pattern applied to the grip of a firearm by a weapon hand of a shooter. This permits the detection of variations in the individual hand grip forces in the pattern during firing of the weapon. This firearm training system preferably also provides for the detection and display as a function of time of the position of the firearm trigger. The system includes separate force transducers for the side and front-to-back grip forces applied to the side surfaces and one of the front and back surfaces of the grip respectively as well as a trigger position sensor. A relative value of the hand grip forces detected by the transducers and a relative trigger position detected by the sensor are graphically displayed by the system as a function of time.
