1. A selective fire firearm, comprising: a lower receiver and a trigger pivotal relative to the lower receiver, the lower receiver including a hammer movable from a cocked position to an uncocked position to fire the firearm, the lower receiver further including a sear assembly and an auto sear that are each positionable to releasably engage the hammer; a grip assembly attached to the lower receiver; an electronic firing system in at least one of the grip assembly and the lower receiver, the electronic firing system including an electronic actuator with a sear displacement member that is movable in response to a pull of the trigger when the electronic firing system is enabled; and a selector mechanism including a mode selector movable between a safety mode position wherein the sear assembly is blocked from movement by the selector mechanism, a semi-automatic firing mode position wherein an upper sear and a lower sear of the sear assembly are movable relative to the selector mechanism to engage the hammer in the cocked position, an automatic firing mode position wherein the selector mechanism blocks movement of the upper sear and the auto sear is positioned by the selector mechanism to temporarily engage the hammer in the cocked position, and an electronic firing mode position in which the electronic firing system is enabled so the pull of the trigger actuates the electronic actuator to move the lower sear to release the hammer from the cocked position and the upper sear and lower sear are movable relative to the selector mechanism to engage the hammer in the cocked position.
