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.
