Abstract
An electromagnetically variable firing system for a firearm includes an electromagnetic actuator including a stationary yoke, a rotating member movable about a pivot axis relative to the stationary yoke and operably coupled to a firing mechanism of the firearm, a trigger operable when pulled by a user to move the rotating member between an unactuated position and an actuated position for discharging the firearm, and a magnetic coil when energized generating a user-adjustable magnetic field which changes a trigger pull force required to be exerted by a user on the trigger to discharge the firearm. A programmable microcontroller is configured to selectively energize the coil for discharging the firearm in response to detecting a trigger pull event. The microcontroller in one embodiment is configured to count each energization of the coil as indicative of a firing event and record the firing event and associated time/date stamp.
