An auto-loading firearm having a system for switching between live fire and training modes via a selector switch mounted either on the firearm or on a specially designed training attachment. An action arm is selectively movable in response to movement of the selector switch between a live fire position, in which the firearm is free to operate as normal, and a training mode position where the action arm interrupts operation of the hammer and prevents the firearm from discharging while allowing the trigger and, if present, trigger spring to continue operating.

A slide stop lever adapted to be disposed in a gun body, and has a pivoting section adapted to be pivoted to the gun body, and a latching section extending rearwardly from the pivoting section. The latching section has a rod portion extending rearwardly from the pivoting section, a latching portion protruding from the rod portion, and a pushed portion protruding from the rod portion and located lower than a top of the rod portion. The pushed portion is adapted to be pushed upwardly to move the latching section upwardly from an initial position to an abutment position, where the latching portion is adapted to be received in a latching groove of the Glock 43 series slide to prevent forward sliding movement of the Glock 43 series slide.

Systems and methods are provided for the making safe of a handgun. A safety system includes a lock mechanism coupled to an engagement member and a user interface. The engagement member is movably coupled to the handgun and includes a contact face that is in contact with the slide of the handgun. The engagement member transfers a portion of a force to the slide and moves between a lock position and an unlock position. The lock position corresponds to a separation distance between a distal end of a primer actuator of the handgun and a primer activation plane. The engagement member is configured to transition between the lock position and the unlock position while remaining movably coupled to the handgun. Movement of the engagement member from the lock position is restricted by the lock mechanism until disengaged via the user interface.

A device implementable on a firearm includes a main body and a paddle portion. The main body includes a bolt catching portion, a first protrusion, a second protrusion, and a pivot portion connecting the bolt catching portion, the first protrusion and the second protrusion. The paddle portion is detachably attached to the first protrusion and the second protrusion of the main body. The paddle portion includes a first paddle, a second paddle, and a connecting portion connecting the first paddle and the second paddle. The pivot portion is pivotably coupled to the wall to allow the bolt catching portion to pivot between a bolt releasing position and a bolt stopping position. The first paddle is coupled to the first protrusion and the second paddle is coupled to the second protrusion.

The invention relates to a bolt stop for an automatic firearm comprising a bolt stop lever that can be moved between a release position and a catch position, and a locking device that can be moved between a standby position and a locking position, for selectively securing the bolt stop lever in the release position, wherein the locking device is disengaged with the bolt stop lever when in the standby position, and is engaged in with the bolt stop lever when in the locking position, the bolt stop lever deactivated in the locking position.

An accessory slide stop is retrofit for commercially available and military application pistols. The slide stop acts as an add-on lever that replaces an existing lever of the pistol. The slide stop helps decrease the time it takes to reload the pistol. The slide stop is an extended body over that which is known in the art. The slide stop optimizes a position from which the slide stop can be hit by the operator, allows the operator to use either hand as the his or her support hand (non-trigger hand) without having to include two slide stops on each side of the pistol, and even changes the direction in which the operator is allowed to hit the slide stop in order to release the slide such that it is consistent with the direction in which the operator's support hand is already traveling as a result of reloading a charged magazine into the pistol.

A lower receiver assembly of a rifle including a lower receiver having a magazine well formed thereon between a distal end and a proximal end, the lower receiver operable to receive a trigger assembly including a trigger, a hammer, and a firing pin. The lower receiver can include an operating rod retention tab coupled with an upper surface of the receiver and the operating rod retention tab extends above the upper surface and is operable to be received in a groove formed in a receiver of an upper receiver.

Bolt catches for firearms, receivers for firearms configured to receive the bolt catches, and firearms including the disclosed receivers and bolt catches. The disclosed bolt catches have a first bolt catch lever having a center element defining an undercut recess configured to optionally receive a connection section of a second bolt catch lever, and a biasing element configured to urge the first bolt catch lever into an idle position; the disclosed receivers are configured to receive the disclosed bolt catches, and the disclosed firearms include a receiver, and a grip and/or a stock, provided that the receiver defines a recess for receiving a second bolt catch lever and/or a plug.
