A firearm training system provides a firearm body having a trigger and a trigger pull sensor circuit. When the trigger is pulled, the trigger pull sensor circuit provides trigger pull path data allowing monitoring of the actual two-dimensional trigger pull path taken by the trigger during the trigger pull. The trigger pull path is graphed on a predetermined map. The system provides a way to monitor trigger pull path to determine whether the trigger has been pulled laterally and/or if the firearm body has moved with respect to a longitudinal axis of the firearm body during the trigger pull. By repeatedly monitoring trigger pulls using the system, a user can train to improve trigger pull technique.
