  • MAGAZINE SPRING AND MAGAZINE ASSEMBLY
    Publication number: 20230266084
    Abstract: A spring for a firearm magazine includes a top attachment leg, a plurality of upper coils connected to the top attachment leg, a plurality of intermediate coils below the upper coils, and a bottom attachment leg below the plurality of intermediate coils. The upper coils are sized and shaped to nest within the intermediate coils when the spring is fully compressed, reducing the solid height of the spring. In some embodiments, at least two complete upper coils and/or at least two complete lower coils nest within intermediate coils. In one example, at least some coils have a rectangular coil shape. The spring can be configured for use in a handgun magazine or a rifle magazine, for example. A handgun magazine and a magazine components kit including the spring are also disclosed.

  • 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.
