Patent ID: 8807007

Claim:
A firearm comprising: a hammer rotatably mounted to a lower receiver, the hammer including an engagement surface; a main sear mounted to the lower receiver and a trigger rotatably mounted to the main sear about a trigger pin, the main sear including an engagement surface that engages the engagement surface of the hammer to prevent the hammer from rotating to fire the firearm; a secondary sear rotatably mounted to the main sear; a switch mounted to the lower receiver behind the trigger and an electronic circuit electrically connected to the switch such that a pull of the trigger closes the circuit in an electronic mode of fire, wherein: in the electronic mode of fire the circuit operates a solenoid in response to the pull of the trigger and the solenoid moves an actuator that rotates the main sear relative to the trigger and about the trigger pin to disengage the engagement surface of the main sear from the engagement surface of the hammer so that the hammer rotates to fire the firearm; and in response to a failure of the solenoid manual continuation of the pull of the trigger disengages the engagement surface of the main sear from the engagement surface of the hammer to fire the firearm.
