Abstract: This disclosure describes embodiments of an ambidextrous or reversible safety mechanism for firearms. The safety mechanism can be utilized on specific rifles and shotguns, for example an AK47, SAIGA or similar firearms, as a retrofit to reposition the existing safety mechanism to a configuration similar to or nearly identical to an AR15, M16 or similar firearms. In this way, personnel familiar with the safety operation of the AR15 or M16 will be able to operate the retrofit firearm without learning the operation of a new mechanism. Once retrofitted, the firearm safety mechanism will have the same visual appearance, action, and “feel” as the firearm with which they are familiar. The distance from the grip (trigger) to the engagement portion of the safety mechanism of the retrofit firearm will be very similar to that of the familiar firearm.

Abstract: A firearm has a frame, a trigger, a trigger bar, a hammer-type firing mechanism including a hammer having a hammer pin connected to the trigger via the trigger bar and a firing pin, and an automatic firing pin block safety mechanism (“automatic safety”) including a flange that is spring biased into engagement with the firing pin and a pivot lock arm rotatably mounted to the hammer pin and releasable engageable with the flange. The flange blocks the firing pin from discharging a chambered round unless and until the trigger is positively actuated. The automatic safety reduces the risk of accidental discharge, thereby rendering the firearm safer.

The disclosed firearm also includes a safety to permit at least one of the sear arm and the breech catch to move out of a motion path of the breech when the breech moves from the fired position toward the cocked position, but to maintain the sear arm in engagement with the breech when the breech is in the cocked position and the firearm is dropped.

Abstract: An integrated or built-in key-operated gun lock having a rotatable swivel arm. The lock is preferably positioned at the fore-end of the pump slide handle so that, when deployed in the locked position, the swivel arm interferes with the forward motion of the slide handle thereby preventing the shotgun trigger from being reset for firing the weapon. This also prevents the shotgun from being locked with an ammunition round chambered. The swivel arm is preferably located between the slide arm and the pump magazine. A stationary ring may be installed on the magazine tube or, depending upon the existing configuration of the shotgun, an existing ring such as the ring commonly used to brace the magazine tube to the gun barrel, may be employed to cooperate with the swivel arm.

Abstract: An adjustable trigger assembly adapted for installation into the carrier of an AK-47 and similar rifles. The assembly features a plurality of adjusting screws to adjust the force required for trigger pull, the over travel of the trigger after firing, and the forward rotational force and angle of a disconnector rotationally engaged in a slot in the trigger to thereby allow for adjustment of the force required during both stages of pull of a two stage trigger to fire the weapon. The device is adapted for engagement with the receiver of a conventional AK-47 in replacement of the original trigger mechanism and may be used with the original hammer or optionally may employ a replacement hammer which features limited contact with the trigger assembly to lessen the trigger pull required for firing.

Abstract: A firearm includes a frame having a trigger guard defined by an upper wall, a lower wall, a rear wall and a forward wall, and a trigger pivotally mounted to the frame, the trigger having a hole passing therethrough. A trigger bar is disposed in the hole and is transversely slideable therein between a fire position wherein the trigger is pivotable with respect to the frame and the firearm may be discharged, and a safe position wherein the trigger bar and the upper wall of the trigger guard interfere with one another such that the trigger is not pivotable with respect to the frame and the firearm may not be discharged. Transverse movement of the trigger bar out of the hole is prevented by contact of the trigger bar with the frame as the trigger bar is pushed in either transverse direction.

Abstract: A manual safety system for reducing the chances of inadvertent discharge of a linear striker fired semi-automatic or automatic pistol equipped with the system. An otherwise conventional pistol is modified by structural changes in the trigger mechanism housing and by the addition of a trigger bar guide, a manually movable safety lever, a pressure plate and a spring. The trigger bar guide and safety lever are mounted to the trigger mechanism housing for linear and pivotal movement, respectively. A portion of the conventional trigger bar, which must be moved in order to effect firing movement of the trigger, is engaged with and blocked by the trigger bar guide which in turn is engaged and blocked by a portion of the safety lever. In order to unblock and enable the firing system, the safety lever is moved by applying pressure to a tab serving as a thumb rest.
