  • Patent number: 6718680
    Abstract: A semiautomatic handgun having multiple safeties includes a body made in two halves and a slide which can move lengthwise on a pair of rails. The hammer is cocked by rearward movement of the slide. The trigger, which has purely translation motion, is blocked from behind except when the user is wearing a special magnetic ring on his trigger finger. A decocker mechanism pushes the firing pin forward and slides the sear back, and prevents release of the hammer until the firing pin is blocked. The firing pin is normally blocked by a cup, which prevents the firing pin from moving forward if the gun is dropped. The cup is moved to an inactive position by a release lever only when the trigger is pulled. A safety lock, which is preferably operated by a special tool, prevents the transfer bar from moving. The firing pin block lever is locked in a downward position when the safety is activated. A hammer block bar prevents the hammer from moving when the safety is on.

  • Patent number: 5555661
    Abstract: The pistol grip magazine adapter provides an insert for the magazine in the handles of hand guns. The insert is designed to fit snugly in the pistol magazine and is of a proper volume or density to reduce the space in the magazine such that only a single row ammunition clip will fit. The insert is attached to the inside walls of the magazine, is an element of the pistol grips or is attached to the bullet clip. With the space reduction, standard single row clips holding up to ten rounds of ammunition may be inserted. However, the higher capacity clips, such as twenty rounds, for which the gun was originally designed will no longer fit. The inserts are formed from one or two pieces of material depending on the particular hand gun requiring the insert.

  • Patent number: 5526600
    Abstract: An extended capacity cartridge magazine assembly for containing and feeding cartridges to a firearm is disclosed. The magazine includes a metal body for containing cartridges having an upper outlet through which cartridges may exit the magazine into the firing chamber of the firearm and a base plate for covering the bottom of the magazine body. A follower body is disposed within the body of the magazine for biasing cartridges toward the upper outlet. The follower body and the magazine body have certain dimensions to prevent an unwanted amount of rotation of the follower body when 0.45 caliber cartridges are being used. A collar slidably movable along the length of the magazine body is adapted to retain the base plate in a fixed position with respect to the magazine body. A flexible bumper plate interconnects with the bottom surface of the collar to secure the cartridge magazine assembly.

  • Patent number: 5473834
    Abstract: The firearm comprises a manual control (13) for deactivation of the retainer of a cartridge magazine (8) by release of a tooth (16) from a notch (17) of the magazine and a device for the automatic ejection of the magazine. The automatic ejection device comprises a finger (25) for the actuation of the tooth (16), which is integral with the cartridge elevator piston (19) of the cartridge magazine (8), to come against the retainer of the latter and cause its ejection before the end of the elevation stroke of the cartridge elevator piston during the chambering of the last cartridge (12) under the thrust of the spring (20) of this piston against an activation spring (18) of the retainer. After the ejection of the empty cartridge, the retainer (13) is again activated by its spring (18) and, during the replacement of this magazine, a cartridge (12) is thus chambered and the firearm is ready to fire.

  • Patent number: 5450683
    Abstract: An improved magazine construction for gas powered firearms or other single object dispensing unit is disclosed. The expanding gasses from the breech or barrel of the gun are directed into the bottom portion of the magazine where they are introduced into a chamber having varying capacity. The upper portion of the chamber is movable and forms the follower, which includes integral biasing means thereon to provide additional impetus for urging the cartridges upwards into the receiver. The body of the follower also includes spring loaded cammed pins that engage cooperating pin holes in the inner magazine wall to provide a ratcheting action as the follower advances. These pinholes also serve as a excess pressure relief, allowing the gasses to escape through a blow by rail located between the inner and outer magazine walls.
