  • Patent number: 5437118
    Abstract: A frame plug or closure member which is fitted into a cavity of a handgrip of a handgun is used to provide added reenforcement and to extend the handgrip. The plug has a tapered, semi-circular shaped base which is integrally connected to one end of a flexible flat, elongated member which has a foot at the other end thereof. The curvature of the base matches the curvature of the lower edge of the handgrip to provide a natural extension to the handgrip. The plug has a spine integrally connected to both the base and flexible elongated member so as to provide stiffness thereto. The handgrip has a plug cavity and an adjacent gun magazine cavity which open to the lower edge or butt thereof. The two cavities are separated by an internal wall having a through opening. The frame plug is fitted into the plug cavity until the foot reaches the opening at which time the foot snap fits into the opening thus securing the frame plug to the handgrip.

  • Patent number: 4768301
    Abstract: An important factor in firearms suitable for combat is the capability to permit replacing the magazine with one hand, that is, to permit the user to eject an emptied magazine by releasing it with the shooting hand and permitting it to drop out automatically, so that a full magazine can be inserted with the free hand. To accomplish this, a latch mechanism is arranged in a through hole formed transversely to the magazine opening and to the longitudinal axis of the barrel of the gun and includes two positive detent latches in a concave or arched portion, the detents being separated by a central groove. The detents have an outer arched or curved surface and on the inside provide straight walls for the groove, in this way a straight magazine can displace the latch axially. The magazine has two pairs of recesses in a rounded leading surface that are arranged so that the two detents seat in the recesses, thereby to accurately support the magazine in two dimensions.

  • Patent number: 4539770
    Abstract: A pressable magazine latch for semiautomatic pistols adaptable for use by either right or left-handed persons includes a guide-tube anchored wihtin the pistol frame which contains a displaceable rigidly connected two-part latch member therewithin. A spring normally maintains the latch member engaged with the magazine and presents a latch member button projecting beyond one end face of the guide-tube. Despressing this button substantially flush with the adjacent guide-tube end wall releases the latch from the magazine while further axial displacement of the latch member allows subsequent disassembly of the two latch parts to permit re-assembly thereof in a reverse position within the guide-tube.

  • Patent number: 4521985
    Abstract: An ambidextrous release for gun magazines in a retrofit design is provided for Colt government model pistols and other similar design semi automatic pistols. The new magazine release catch has much of the basic configuration of the original equipment catch but instead of a solid catch it has a pivotal lever, with a cam surfaced catch on the end to engage the magazine, that is pivot pin mounted in the gun magazine catch lock release structure. The structure is lengthened to also extend outward beyond the gun right hand surface with a right side button on the right hand end. The magazine lock release right side button with proper manipulation combined with pressure from the other end and turning achieves dog projection release removal and, in reverse, installation thereof without requiring the use of a screw driver or any other tools. A simple dog slot extension is machined within the gun receiver to allow for installation and movement of the new magazine release catch.
