The invention generally relates to a replacement grip for a pistol. More particularly, the invention relates to a pistol grip with a magazine catch release for a pistol with a heal catch release.
Makarov pistols were widely used by the Soviet Union as service weapons for the police and military from approximately 1951 to 1991. Militaries and police forces may continue to use these pistols as service weapons today. Accordingly, the Makarov pistol may be considered an icon of Russian firearm design, and may possess an enduring reputation for reliability, economy, ease of manufacturing, and reasonable stopping power. As such, the Makarov pistol may include a heal clip magazine release, which reportedly was designed for two handed operation to promote reliable operation during combat.
Hence, the present disclosure is directed toward a replacement grip for a Makarov pistol which includes a magazine catch release that may provide one handed operation of the heal clip magazine release. Hence, the grip may be for a gun with a frame having an upper portion and a lower portion, a slide connected to the upper portion of the frame, an ammunition magazine receptacle situated within the lower portion of the frame, and a spring secured to the frame. The spring may include a lower end adjacent to the lower end portion of the frame.
In one embodiment, the grip for the gun may include a body which includes a top end portion, a bottom end portion spaced from the top end portion along a first longitudinal axis, an exterior surface extending from the top end portion to the bottom end portion, a first interior side wall, a second interior side wall opposite the first interior side wall, and a third interior side wall disposed between the first interior side wall and the second interior side wall. The third interior side wall may include an intermediate region, a bore extending from the exterior surface to the intermediate region, and an inferior pocket located between the intermediate region and the bottom end portion.
The body may include a first lever connected to the first interior side wall, the first lever including a first end portion adjacent the top end portion of the body and a second end portion, proximate the bottom end portion. The second end portion may include a projection extending toward the second interior side wall. The first lever further may include a first interior side wall attachment site located between the first end portion and the second end portion. The first lever may be movable about the first interior side wall attachment site between a first position and a second position such that in the first position the projection is spaced a first distance from the third interior side wall, and such that in the second position the projection is spaced a second distance from the third interior side wall, the second distance being less than the first distance.
The first interior side wall may include a first elongated recess and the first lever may be connected to the first interior side wall within the first elongated recess. The first elongated recess may include a front wall adjacent the first interior side wall, and a rear wall adjacent the first interior side wall. The first lever may be pivotally connected to the first interior side wall such that in the first position the first end portion is proximate the rear wall, and such that in the second position the first end portion is proximate the front wall.
The first lever may have a mechanical advantage greater than 1.0. Preferably, the grip may have a mechanical advantage greater than 2.0. More preferably, the first lever may have a mechanical advantage substantially equal to 2.2.
The first end portion of the first lever may include an actuation surface. The actuation surface may project away from the exterior surface of the body. The body further may include an opening extending from the exterior surface to the first interior side wall. The actuation surface may be disposed in the first opening.
The first opening may be an indentation in the top end portion of the body. The first opening may include a rim extending from the exterior surface to the first interior side wall. The rim may form a curve. The curve may have a radius centered at the first interior side wall attachment site. For example, the radius may be substantially equal to 50 mm.
The first interior side wall may be on the port side of the grip. The body may further include a shim connected to the second interior side wall. Alternatively, the first interior side wall may be on the starboard side of the grip. The body may include a second lever connected to the port interior side wall or a shim connected to the second interior side wall.
A pistol grip conversion kit for a Makarov variant pistol may include a grip in accordance with this disclosure, a second lever configured and dimensioned to be connected to the second interior side wall; a first shim configured and dimensioned to be connected to the first interior side wall; a second shim configured and dimensioned to be connected to the second interior side wall; and instructions for replacing a Makarov pistol grip with a grip described in accordance herein.
In the accompanying drawings, which form part of this specification and are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views:
Referring to
Although the grip 26 may be of unitary construction (i.e. one structural body), the grip may be composed of two or more pieces, provided that the component parts may be assembled into to a secure and stable grip. For example, the grip may be formed of two halves that may be secured to each other by one or more fasteners (e.g. a machine screw). Also, the grip 26 may be formed from one or more materials e.g. metal, metal alloys, wood, plastic, polymer materials, reinforced polymer materials, thermoplastic materials, and combinations thereof.
The exterior surface of the grip may include textured regions 46 to enhance the stability, gripping characteristics, or ergonomic fit of the pistol grip. The grip 26 may include an interior space (e.g., a generally U-shaped channel) 48 that is configured and dimensioned to mount on the lower portion (or handle) of the frame. Additionally, the grip 26 may present one or more mechanisms 50 that may be used to release the magazine catch 52 that is located near the base of the grip. In the disclosed embodiment, the mechanism includes a lever. Other mechanical or electromechanical mechanisms also may be used provided they provide a secure and reliable device for selectively releasing the magazine catch.

For example, the instructions may include, without limitation, the following steps: removing the grip and internal components from the kit; visually inspecting the grip and the internal components removed from the kit; placing a magazine catch release lever in an elongated recess of an internal sidewall of the grip; positioning a portion of the magazine catch release lever in a cut out in the internal sidewall which is proximate to the elongated recess; inserting a pin through an aperture in the internal sidewall; inserting the pin through a hole in the magazine catch release lever; and securing the magazine catch release lever to the grip by connecting a retention element to the pin.
The instructions further may include placing a shim (or another catch release lever) in another elongated recess of the grip, the other elongated recess being disposed on another internal sidewall of the grip; positioning a portion of the shim (or other magazine catch release lever) in another cut out in the other internal sidewall which is proximate to the other elongated recess; inserting another pin through another aperture in the other internal sidewall; inserting the other pin through another through hole in the shim (or other magazine catch release lever); and securing the shim (or other magazine catch release lever) to the grip by connecting another retention element to the other pin.
The instructions further may include mounting the grip onto the frame of the pistol; positioning one (or more) raised surface(s) on the internal side wall(s) of the grip into a corresponding opening(s) in the frame; aligning the grip screw receiving bore on yet another internal side wall of the grip with a receiving bore on the pistol frame; advancing a grip screw though the receiving bore, the spring retainer and the trigger and the hammer spring of a Makarov variant pistol; and the receiving bore on the pistol frame to fix the grip to the frame and then securing the pistol to the frame by advancing a threaded fastener through the grip and into the frame. The instructions may include pulling the frame toward the rear internal side wall of the grip; and pressing the
In use, an operator may push a thumb lever forward (i.e., toward the distal end of the pistol). This action rotates the magazine catch release about the magazine catch release pivot pin, which causes the hook to move away from the frame. Movement of the hook away from the frame draws the loop away from the frame as well. Sufficient movement of the hook away from the frame causes the catch on the loop to disengage with the magazine latch so that the magazine may be removed or changed. As the thumb lever is released from the actuated position by the operator, the loop and thumb lever may return to their initial positions under forces applied by the lower, displaced portion of the hammer and trigger spring.
While it has been illustrated and described what at present are considered to be preferred embodiments of the present disclosure, it will be understood by those skilled in the art that various changes and modifications may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the invention. For example, the shape of the thumb lever or indentations may be modified for ergonomic or operational considerations. Also, different fastening means may be used to connect the catch release levers and shims to the body of the grip. In one example, the catch release lever may be snap fit mounted on to a projection of the interior side wall of the body. In another example, the catch release lever and shim may include a projection that is press fit into a mating recess in the interior side wall of the body. Additionally, features and or elements from any embodiment may be used singly or in combination with other embodiments. Therefore, it is intended that this invention not be limited to the particular embodiments disclosed herein, but that the invention include all embodiments falling within the scope and the spirit of the present invention.
