A new interface for a magazine follower and floor plate is used to provide greater stability to the round stack and a more sturdy system overall. The floor plate is designed with two opposite legs, the rear being shorter than the front leg so as to facilitate travel throughout the magazine and clearing of accumulated dirt and debris. The floor plate, in one embodiment, utilizes a lock plate that is shaped and sized to become a shoe for the compressed spring and associated follower. In an alternate embodiment, the floor plate itself serves the purpose and, with provided teeth, directly fastens to the magazine casing at notches manufactured in the magazine wall for that purpose. Other enhancements to the magazine include at least one matrix of divots to provide a paint surface, an over-insertion stop and a lower rear geometry to aid in clearing debris and grit.

A firearm magazine loader and unloader accessory (10) comprises a main body (12) adapted to fit over an open end of a magazine (70) and a tiltable alternate round thruster (50) mounted in the main body above the magazine's open end. The alternate round thruster includes two plungers (62) and (64), each positioned above a column of rounds (80, 82) of the magazine. Loading is achieved by thrusting inside the magazine the topmost round of the magazine using the plunger above to provide a vacant space for a new round to be rearwardly inserted. Unloading is achieved by thrusting inside the magazine the second-to-topmost round of the magazine with the plunger above to release spring (78) pressure from the topmost round so that it can gravitationally and forwardly unload.

The invention relates to a grip for a handgun, in particular a pistol, having a grip module (1) made of plastic and a metal carrier element (2) that is insertable into said grip module (1). In order to enable a simple and cost-effective adaptation to the widest variety of demands of the marksman, a magazine shaft (4), projecting downward from the grip module (1) and onto which is slipped a grip shell module (3), is formed as a part of the carrier element (2).

A rotary magazine for a firearm includes a hold-open lever that is actuated after the last shot is fired to hold the bolt in an open condition to signify that the magazine is empty. No modification to the firing mechanism, bolt or other part of the firearm is required. The hold-open lever is tripped to a hold open position by a stud or similar trip mechanism mounted to the magazine's rotor. The rotor and the magazine's feed insert are formed in a manner such that the rotor rotates an additional amount beyond its nominal original position (magazine empty), without interference from the feed insert or other structures in the magazine. When this additional rotation occurs, the trip mechanism on the rotor actuates the lever, moving it to a position in which it blocks the forward movement of the bolt. Several different arrangements for a rotary magazine with the hold open feature are described.

A conversion kit for converting a semi-automatic or self-loading handgun of a certain caliber, such as a Colt .45, is modified to allow the use therein of cartridges of a different, usually smaller caliber, thus to allow less expensive training on the handgun, wherein only the barrel and magazine need to be replaced, the barrel having thereon a sliding extractor that cooperates with the original slide in the ejection and reloading of cartridges, and an off-axis bore adjusted to compensate for the difference in the reloading mechanism and the lesser rise of the handgun when firing the lower caliber ammunition, thereby allowing retention of the sighting, safety features, and mechanical functions of the original handgun while closely duplicating the original weight.

A shell stripper assembly includes a shell stripper, a stripper guide, a stripper guide plate, and a magazine insert. The shell stripper strips the top round from the firearm magazine so that it can be picked up by the firearm breech bolt. The shell stripper slides between guide rails of the stripper guide, and its motion is controlled by the stripper guide plate.

The present invention provides a grip extender for a handgun. The grip extender provides a relatively continuous surface between the handgun and locked magazine to afford the handgun user with a comfortable grip. The grip extender can be adapted to fit a variety of handguns and magazines.

A magazine loader (10) for firearm magazines (40) has a projecting side button (50) coupled to a follower (52). Two similar and substantially flat flaps (12, 14) are hinged by a pin (18) along their longer side. A torsion spring (16) encompasses the pin and is positioned between the flaps, forcing them apart. Each flap has a substantially rectangular opening (20A, 20B) sized and positioned to fit over a magazine. The flaps can angle between an open position and a closed (parallel and touching) position. To load the magazine, a user squeezes and holds the flaps ends closed to align the openings so that the openings can be slid over the magazine to push the button down. Upon releasing the flaps they open, locking the openings on the magazine. Rounds (60) then can easily be loaded into the magazine. The loader may use a grasping member in lieu of flaps.

A magazine adapter includes a base that is structured to fit within the magazine well of a firearm, and to accept a magazine designed for smaller caliber ammunition than the original firearm. The adapter includes a bolt catch actuator slidably mounted therein. Magazines for which the adapter is intended include an upwardly extending rear projection of the follower, projecting from an opening in the rear of the magazine housing when the follower is in an upper portion of the magazine. When the upwardly extending projection pushes upward on the bolt catch actuator, the bolt catch is actuated, holding the firearms bolt in a rearward position. The magazine adapter thereby facilitates use of the original firearm controls with a caliber conversion unit, or with an upper receiver and barrel combination of a different caliber.

A firearm comprising: (i) an ammunition magazine which automatically ejects from the lower receiver of the firearm when the ammunition magazine is spent; (ii) a control group comprising a magazine release mechanism for releasing the magazine catch so that the ammunition magazine is detachable from the lower receiver, a bolt catch engage mechanism for engaging the bolt catch with the bolt carrier and retaining the bolt carrier in the retracted position, and a bolt catch release mechanism for releasing the bolt catch from the bolt carrier and allowing the bolt carrier to move forward, wherein the control group components can be operated by the user on either the left side or right side of the firearm; and (iii) optionally, a charging handle which can be operated by the user on either the left side or right side of the firearm.

A mechanism for selectively connecting a magazine tube to a receiver of a magazine fed shotgun. The mechanism permits the rapid attachment to or detachment from of the magazine tube to the receiver of the shotgun. The mechanism may be a connector threaded into the end of the magazine tube. A locking profile may be connected to the end of the connector and may provide an access path. A pin may be passed through the access path and the magazine tube may then be rotated to position the pin into the locking profile. The rotation may be less than one half of a rotation. A plug may be threaded into the receiver. The pin may be connected to the plug. A spring may be used to bias the magazine tube in a locked position. A protrusion and nut may prevent movement between the magazine tube and receiver.
