US12398966 - Backward compatible safety slide firing pin-striker system

A firearm system which allows firearm disassembly without trigger actuation. The system includes a slide having a divot or cavity disposed laterally off of the main channel. This divot allows for the pivoting of the striker sleeve such that the striker tang sear can move between a first position that is engaged with a corresponding trigger bar sear of a frame and a second position whereby the striker tang sear is disposed at least partially within the divot. This allows the striker tang sear to clear the trigger bar sear for disassembly without requiring a pull of the trigger.

The patent describes a firearm system that enables disassembly without pulling the trigger by incorporating a slide with a lateral divot that allows the striker tang sear to disengage from the trigger bar sear. This innovative design enhances safety during maintenance by facilitating the striker’s movement to a position that clears the trigger mechanism.

Claim 1

A system for safely disassembling a firearm, comprising: a slide having a channel, the channel dimensioned to receive a striker sleeve; the striker sleeve disposed within the channel and dimensioned to receive a striker; the striker having a striker tang sear, wherein the striker tang sear is aligned with a trigger bar sear of a frame of the firearm when the striker tang sear is at a first tang sear position; and wherein the slide includes a divot extending laterally from the channel, the divot disposed on the slide such that the divot becomes aligned with the striker tang sear when the slide is at an open action state, and the divot dimensioned to at least partially receive the striker tang sear when the striker tang sear is moved to a second tang sear position. a slide having a channel, the channel dimensioned to receive a striker sleeve; the striker sleeve disposed within the channel and dimensioned to receive a striker; the striker having a striker tang sear, wherein the striker tang sear is aligned with a trigger bar sear of a frame of the firearm when the striker tang sear is at a first tang sear position; and wherein the slide includes a divot extending laterally from the channel, the divot disposed on the slide such that the divot becomes aligned with the striker tang sear when the slide is at an open action state, and the divot dimensioned to at least partially receive the striker tang sear when the striker tang sear is moved to a second tang sear position.
