Abstract: A trigger assembly has a trigger rotatable about a trigger axis of rotation between a resting position and a pulled position, where the trigger has a trigger shoe and a trigger body. A sear has a catch surface, is located forward of the trigger, and is rotatable about a sear axis of rotation between an engaged position and a disengaged position. A trigger bar links the trigger to the sear such that moving the trigger from the resting position to the pulled position causes the sear to rotate from the engaged position to the disengaged position, or vice versa. The trigger assembly can be housed in a lower receiver compatible with an upper receiver of an autoloading firearm.

Abstract: A slide for a semiautomatic handgun includes a slide body extending along a bore axis and having a top wall, side walls extending downward from lateral margins of the top wall, and a distal end defining a distal opening intersected by the bore axis. The slide body defines an open region between the top wall and the side walls, the open region sized and configured to receive a barrel of the semiautomatic handgun extending along the bore axis and so that a muzzle end of the barrel is spaced axially from the distal end of the slide body. A distal end portion of the top wall defines one or more ports positioned between the distal end of the slide body and the muzzle end of the barrel to be received in the open region.

Abstract: A hinge joint includes first and second hinge leaves pivotably mounted on a hinge pin, where the hinge joint is operable between open and closed positions. The hinge joint has a locking mechanism that prevents opening the hinge joint from a closed position until the locking mechanism is moved to the unlocked position. In one example, the locking mechanism includes a plunger retained in the hinge pin. When the plunger is depressed, one or more protrusions can move from a blocking position to a non-blocking position. In some embodiments, the locking mechanism must be moved to the unlocked position prior to opening the hinge joint. The locking mechanism may be used alone or in combination with engagement structures between the first and second hinge leaves. The hinge joint can be part of a folding rifle stock assembly or other hinged assembly.
