ABSTRACT:
A trigger pull measuring device adapted for connection to the trigger mechanism of a weapon for measuring the trigger pull of the weapon in order to improve trigger pull technique, comprising a variable resistor having a sliding contact for varying the resistance of the resistor, connected to a voltage source, and a linkage for connecting the sliding contact of the variable resistor to the trigger mechanism of the weapon so that movement of the trigger moves the sliding contact of the resistor. The device further comprises a battery for applying a voltage across the variable resistor and a chart recorder for measuring and displaying the resistance across the variable portion of the variable resistor to measure the position of the trigger.
The method of the present invention comprises a method of improving trigger pull technique for firing a weapon with a trigger, the method comprising the steps of continuously measuring trigger displacement as the trigger is pulled and displaying the trigger displacement to the person firing the weapon, to enable the person to correct defects in trigger pull technique.
