Abstract: A gauge for measuring the force required to discharge a firearm by pulling its trigger includes a housing and a rod including a trigger hook portion at a distal end thereof for engaging the trigger. A load cell is connected to the housing and to a proximal end of the rod such that the load cell generates an electrical signal in response to forces on the rod as the housing is pulled while the trigger hook portion is engaged with the trigger. The magnitude of the electrical signal is proportional to the forces on the rod. A microcontroller receives the electrical signal and calculates a force value based thereon. The microcontroller also continuously monitors the forces on the rod and identifies a trigger pull value of the firearm as being the maximum force on the rod until pulling on the housing is ceased once the trigger of firearm has released.
