  • Handgun sear with multiple engagement surfaces
    Patent number: 10684087
    Abstract: A handgun sear has a sear body extending between a proximal end portion to a distal end portion. The sear defines a first engagement surface adjacent the proximal end portion and a second engagement surface positioned distally of the first engagement surface. The sear can pivot about the distal end portion between a cocked position and a displaced position. The second engagement surface can be used to arrest forward movement of the striker in the event of an impulse that causes the striker to disengage from the first engagement surface. The sear may be incorporated into a fire control assembly of a semiautomatic handgun or other firearm.

  • Rear sight mounting assembly for a firearm
    Patent number: 10024628
    Abstract: A firearm slide includes a mounting plate that is removably connected to a planar mounting surface of the firearm slide. A rear sight is removably attached to the mounting plate so that different types or styles of rear sights may be used with the firearm. Upon removing the mounting plate itself, various mounting features defined in the planar mounting surface of the slide are exposed. These mounting features can be used to attach any of a variety of accessories (whether a telescopic sight, a red dot sight, a light, or other accessory) directly to the exposed planar mounting surface of the slide.
