Abstract
A lock for a firearm with a grip safety, and a sear engageable to a biased hammer in a cocked position and releasable by a trigger is disclosed. The lock has a housing defining a first bore within which a mainspring that biases the hammer is received, as well as a second bore. There is a locking pin retractable into and extendible out of the second bore of the housing. When the locking pin is in an extended position, the grip safety is restricted to an engaged state, blocking movement of the trigger. An actuator disposed in the housing and cooperatively linked to the locking pin provides the motive force for retracting and extending the locking pin.
Claims16
A lock for a firearm with a grip safety, and a sear engageable to a biased hammer in a cocked position and releasable by a trigger, the lock comprising:
- a housing defining a first bore within which a mainspring that biases the hammer is received, and a second bore;
- a locking pin retractable into and extendible out of the second bore of the housing, the locking pin in an extended position restricting the grip safety to an engaged state, blocking movement of the trigger;
- an actuator disposed in the housing and cooperatively linked to the locking pin, the actuator providing the motive force for retracting and extending the locking pin.
A firearm, comprising:
- a frame;
- a hammer pivotally mounted to the frame and defining at least one sear engagement surface corresponding to a cocked position and a firing pin striking surface;
- a hammer strut linked to the hammer;
- a sear pivotally mounted to the frame and defining a hammer engagement surface frictionally engaged to the sear engagement surface of the hammer;
- a disconnector selectively engageable to the sear;
- a trigger including a trigger bar in frictional engagement with the disconnector;
- a mainspring housing assembly attached to the frame and defining a first bore receptive to a mainspring and a mainspring cap, the hammer strut being retained in the mainspring cap in compression against the biasing of the mainspring and the hammer in the cocked position being resultantly biased against the sear, movement of the trigger bar against the sear releasing the hammer from the sear;
- a safety latch having a set position blocking movement of the sear;
- a grip safety including a trigger stop with a released position blocking movement of the trigger bar and a depressed position allowing movement of the trigger bar;
- and
- a secondary lock including an locking pin having a first position extending from the mainspring housing and a second position retracted within the mainspring housing, the pin blocking movement of the grip safety in the first position and permitting movement of the grip safety in the second position.
