The invention is a handgun in which the spring-loaded slide is replaced by an electric motor, engageable only upon an authorized user entering an access code. A combination rechargeable battery and keypad engages the butt of the handle where the magazine well is located and includes an electrical plug the fits into the handle, making an electrical connection between the battery and a microprocessor in the handgun. Entering the proper code on the keypad allows the microprocessor to complete the circuit between the battery and a motor that actuates the slide. When the device is not in use, the magazine having been removed, the motor then moves the slide rearward, ejecting any cartridge in the chamber, and maintains the slide in a position where the chamber is always open, thereby making obvious to anyone that the gun is not loaded.

The magazine assembly includes a canister, a door structure, a feed pawl and a follower structure. The canister is configured to hold a plurality of collated fasteners and has a first canister portion and a second canister portion that is movable relative to the first canister portion between a closed position and an open position. The fastening tool further includes a coil feeder assembly having an indexing pawl. The indexing pawl advances a fastener into operative engagement with the feed pawl upon movement of the second canister portion from the open position to the closed position.

A safety device including a locking member which is inserted and locked within the barrel and firing chamber of a firearm to prevent firing of the same is provided. The locking member preferably includes a rod having a leading or first end which is at least partially insertable within the firing chamber of the weapon, and an outer sleeve including a trailing or second end which is expandable in a first direction to produce a tight frictional engagement between the sleeve and the inner wall of the barrel in order to secure the locking member within the firearm. The rod is at least partially insertable within a cavity in a first end of the sleeve such that the overall length of the locking member is adjustable to fit different weapons, for example a revolver and an automatic pistol. The second end of the sleeve preferably includes a pair of slots dividing the sleeve into first and second sections which expand in the first direction within the barrel of the firearm upon insertion of an expansion member, such as a wedge or threaded screw, into an opening in the second end of the sleeve. A compression spring is also preferably provided, the spring being disposed within the cavity of the sleeve, between the rod and the sleeve, such that the spring biases the rod longitudinally, i.e., outwardly and away from the sleeve in an uncompressed state. The spring allows the overall length of the locking member to be adjusted within the firearm, particularly for extending the length of the locking member into the firing chamber of an automatic pistol upon removal of the magazine. A locking key is also provided for inserting the expansion member into the second end of the sleeve in order to expand the same. In one embodiment, the key is part of a key assembly which includes an engagement member for holding the outer surface of the sleeve to prevent rotation. The engagement member may also be utilized to remove the locking member from within the firearm.

A safety magazine is compatible with a firearm that has a magazine housing. The safety magazine comprises a top cover that has a shape compatible with the magazine housing, a bottom cover that covers a locking mechanism, and a top locking element that at least partially accommodates inside the top cover. The locking element is configured to allow locking the safety magazine to the magazine housing. A method for locking a magazine to a firearm and preventing accidental discharge is disclosed. The firearm has a magazine housing. The method comprising providing a top cover, that has a shape compatible with the magazine housing, providing a bottom cover, covering a locking mechanism, providing a top locking element, and inserting the top cover into the magazine housing, wherein the locking element is configured to allow locking the safety magazine to the magazine housing

The present invention is an automatic firearm magazine loader that has an elevated hopper system, a loading system, and a mechanism for compressing a firearm magazine comprising a spring mechanism. The firearm magazine is compressible upon compression of the spring mechanism. The loading system facilitates the loading of a firearm ammunition into the firearm magazine upon the compression of the firearm magazine, and the compression of the firearm magazine is motor driven. The device is an automatic firearm magazine loader for a designated number of rounds of ammunition. The design consists of a user interface used to select the preferred number of rounds of ammunition to load, a hopper system which feeds individual rounds of ammunition in a set orientation, and a loading system which loads the individual rounds of ammunition into a firearm magazine.

An ambidextrous magazine catch mechanism for a pistol includes a button in the pistol frame. The button has a W-shaped camming surface. A magazine has a catch aperture. A catch includes two upwardly disposed legs connected to one another. A first leg has a tooth to mate with the catch aperture. The first and second legs form a spring having an equilibrium position. When the first leg is pressed toward the second leg, an outward force on the first leg biases the catch toward the equilibrium position. The first leg has a W-shaped camming surface to mate with the camming surface of the button. The button has a neutral position, and a first and second depressed position. In the neutral position, the camming surface of the button mates with the camming surface of the first leg and the tooth is engaged in the aperture to secure the magazine. In the first depressed position, a first side of the button is depressed such that the camming surface of the button moves against the camming surface of the first leg such that the first leg is urged toward the second leg to disengage the tooth from the magazine.

A magazine-based firearm interlock that can be added to a commercial firearm, with a release / locking device on the firing mechanisms enabled by an electro-permanent magnet, control electronics in the removable magazine, and authorized through a wearable authorization device. Modifications are applied to the trigger bar or sear mechanism which enables it to be changed to an unlocked state, which allows a shot to be fired, and to a locked state, which prevents a shot from being fired. A communication system includes a chip set in the firearm magazine that communicates with a FOB carried by the user, which authenticates the user and activates the electro-permanent magnet to enable the firearm to fire. This system is preferably a near field communication system that couples to and transmits across the body of the user. Indicators can be included to indicate the operational state of the interlock and to detect and record discharges.

A firearm magazine that is designed to make the loading of cartridges easier and faster, while being constructed of fewer parts for higher reliability and with no protruding elements that preclude its use in pre-existing firearms.
