Abstract
A striker-fired firearm with field stripping mechanism and method. A striker-fired firearm generally includes a frame, a slide supported by the frame for longitudinal forward and rearward movement, a striker axially movable in a path of travel along a longitudinal axis, a trigger pivotably connected to the frame, a trigger bar movably coupled to the trigger and adapted to engage the striker, and a trigger bar camming member pivotably disposed in the frame and defining a camming surface engaged by the trigger bar. Pivoting the camming member moves the trigger bar from a first position to a second position in spatial relationship to the striker. In a preferred embodiment, the camming member is an ejector operable to expel spent cartridge casings from the firearm.
Claims19
A striker-fired firearm comprising:
- a frame defining a longitudinal axis;
- a slide supported by the frame and longitudinally movable thereon;
- a striker disposed in the slide and movable in concert with the slide along a longitudinal path of travel between a forward position and a rearward position;
- an ejector pivotably disposed in the frame and operable to expel spent cartridge casings from the firearm;
- a trigger bar movably engaged by a camming surface of the ejector and connected to a trigger movably mounted to the frame, the trigger bar being movable into and out of the longitudinal path of the striker between alternating blocking and nonblocking positions respectively by pivoting the ejector.
A method of operating a striker-fired firearm comprising:
- providing a firearm including a frame defining a longitudinal axis, a striker movable along a longitudinal path of travel, a trigger pivotably connected to the frame, a trigger bar movably coupled to the trigger and adapted to engage the striker, and an ejector engaging the trigger bar;
- moving the ejector;
- and
- displacing the trigger bar with respect to the striker.
A method of operating a striker-fired firearm comprising:
- providing a firearm including a frame defining a longitudinal path of travel, a striker carried by a slide supported on the frame for sliding movement and being movable in concert with the slide along the longitudinal path of travel, and a trigger bar movably coupled to a trigger mounted to the frame and having a catch adapted to engage an operating protrusion on the striker, the trigger bar being movable between a blocking position wherein the catch blocks the longitudinal path of travel and an nonblocking position wherein the catch does not block the longitudinal path of travel;
- engaging the trigger bar with an ejector mounted in the frame for pivotable movement;
- pivoting the ejector and essentially simultaneously moving the trigger bar from the blocking position to the nonblocking position;
- and
- sliding the slide and striker forward such that the operating protrusion of the striker moves forward past the catch of the trigger bar.
A method of operating a striker-fired firearm comprising:
- disposing a trigger bar movably in the firearm;
- locating a striker in the firearm in a spatial relationship to the trigger bar;
- engaging the trigger bar with an ejector operable to eject cartridges from the firearm;
- using the ejector to change the spatial relationship between the striker and the trigger bar.
