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.
