Abstract
A device for measuring the entire profile of a firearm's trigger performance. This device may be either hand held or permanently mounted. The device may be connected to a sensor for sensing strike of the firing pin and connected to a computer for graphically and numerically displaying data relating to the firearm's performance. The device is capable of calculating key firearm performance parameters, including lock time and roughness of the trigger profile.
Claims13
A trigger analyzer comprising:
- a microprocessor electrically connected to a stepping motor for controlling operation of said stepping motor,
- a stationary jaw secured to and extending outward from said stepping motor, said stationary jaw removably engaging a trigger guard of a firearm,
- a moving jaw movably connected to said stepping motor so that said stepping motor causes said moving jaw to travel linearly and so said stationary jaw and said moving jaw are approximately parallel and lie in a common plane, said moving jaw removably engaging a trigger of the firearm, and
- a strain gauge provided on said moving jaw for measuring force on said trigger, said strain gauge electrically connected to said microprocessor in order that force measurements are transferred to the microprocessor where the force measurements are continually displayed on a first indicating display which is electrically connected to said microprocessor.
