Patent ID: 6854975

Claim:
A gauge for measuring the force required to discharge a firearm by pulling its trigger, said gauge comprising: a hand holdable housing sized and configured to be held by hand or fingers; a rod including a trigger hook portion at a distal end thereof for engaging the trigger of the firearm; said housing being pullable by hand when said rod trigger hook portion is engaged with said trigger of said firearm; a load cell connected to said housing and to a proximal end of said rod such that said load cell generates an electrical signal in response to forces on said rod as said housing is pulled while the trigger hook portion of said rod is engaged with the trigger of the firearm, the magnitude of the electrical signal being proportional to the forces on said rod; a microcontroller for receiving the electrical signal and for calculating a force value based thereon, said microcontroller continuously monitoring the forces on said rod and identifying a trigger pull value of the firearm as being the maximum force on said rod until pulling on the housing is ceased once the trigger of firearm has released; and a display for displaying the trigger pull value of the firearm identified by said microcontroller.
