Abstract: A system and apparatus for preventing unauthorized access to a trigger of a firearm comprises a database of PIN numbers associated with a plurality of trigger locks and access tokens, each corresponding trio being represented by a common identification code. At a point of purchase, a consumer receives a two-piece trigger lock secured about the trigger of a purchased firearm as well as an access token. Each token includes a unique number or configuration of ferro-magnetic wires. Each trigger lock includes a magnetic read head which generates voltage pulses when a token is positioned in close proximity thereto. This positioning causes the ferro-magnetic wires to switch magnetic states, thus invoking electromagnetic impulses. If a background check of the firearm purchaser, initiated at the point of purchase, is approved, a central computer coupled to the database and to a computer network displays a personal identification number (PIN).

When the screw has been inserted into the aperture, there are two function positions. In a use position, the screw is contained in the trigger and does not substantially project from the trigger.

Abstract: A safety locking device for engaging the trigger guard assembly of a firearm. A preferred embodiment includes a housing having a slot formed therein and configured to receive the trigger and trigger guard portion of a firearm, and a locking mechanism to prevent removal of the firearm from the device. The locking mechanism further comprises a locking assembly operably attached to a locking rod which can be moved into or out of a channel containing a ball that when held in place by the rod causes the slot that contains the trigger guard to narrow sufficiently to prevent the removal of the trigger guard and thus the firearm. The lock may comprise a conventional key-operated lock or an electronic lock. The locking device is designed primarily to be incorporated into a holster.

Abstract: A gunlock that is semi-permanently attached to the trigger guard of a firearm. The gunlock is designed to stay attached to the trigger guard both when the firearm is locked and unlocked. A trigger jam simply moves into a locked position where it locks the trigger in a rearward or forward position. Once the correct combination has been entered via thumb-wheels, a push-button quickly releases the jam. If complete removal of the gunlock is desire able, a second push on the push-button completely release the gunlock. An alternative design of this gunlock incorporates the lock as an integral part of the trigger guard. Its compact streamline design provides an attractive appearance.

Abstract: A safety locking mechanism for weapons that have a trigger and a protective trigger guard. The mechanism includes a housing defining an internal space and a lateral opening through which a slidable spring biased plate protrudes and is brought out in a parallel and space apart relationship with another plate that is rigidly mounted to the housing. A headed post and a separated and removable body member are mounted to the fixed plate and receive the trigger inbetween. The body member conforms to the space between the rear of the trigger and the guard thereby immobilizing it. A locking assembly inside the housing is selectively actuated to release a latch that holds slidable plate inside. The slidable plate and the rigid plate sandwich a trigger and trigger guard to prevent access thereto.

Abstract: A method of preventing access to the firing mechanism of a handgun, or other similar firearm, is provided in which a keyed rotationally activated locking cylinder is employed to secure the invention to the trigger guard of the handgun. Additionally, the invention also employs a device which will hold the slide of the handgun in a rearward manner while the invention is in place. This allows for the access to the handgun's chamber, which enables a user to insert and remove a magazine from the weapon while the invention is in place, and which makes it impossible for the accidental discharge of a bullet from the handgun to be caused by the firing pin.
