  • Handgun safety mechanism
    Patent number: 10724814
    Abstract: A takedown lever assembly for a striker-fired handgun. The takedown lever assembly includes a takedown actuation lever operable between a firing position and a takedown position, and a safety bar operatively coupled to the takedown actuation lever. The safety bar moves longitudinally along the frame in response to moving the takedown actuation lever from the firing position to the takedown position, thereby causing the sear to disengage from the striker.

  • FIREARM WITH INTEGRATED POWER SOURCE
    Publication number: 20170205191
    Abstract: A firearm is described that includes an integrated power source, socket, and conductor connecting the power source to the socket. By integrating these elements into a firearm, a powered accessory can be attached to the firearm without the need for a mounting rail attached to a firearm. Furthermore, powered accessories need not have their own integrated power sources, but rather can connect to the power source within the firearm. This reduces the weight and physical dimensions of both firearms and accessories.
