Abstract: An extended cartridge magazine longer than a pistol grip length needs to have the gap between the base plate of the magazine and the butt end of the grip filled. The present invention provides a sleeve to fill this gap that can be easily slid on and off the magazine by applying simple pressure to the ends of the sleeve.

Abstract: A three position, selectively openable twist lid for a drinking vessel has separate drinking and venting apertures. The lid has two parts—a base member and a cap member. The base and cap members can be relatively rotated from a first, closed position to a second, open position and to a third, disengaged position in which the cap and base members may be separated for cleaning.

Abstract: An angled pistol grip for use in a semiautomatic weapon. Said pistol grip oriented asymmetrically from the centerline of the rifle body thereby reducing the stress on the shooter's wrist of the hand holding said pistol grip while firing. Thus allowing the shooter to correctly position the weapon, relative to the shooter's body, for accurate aiming.

Abstract: A finger tang incorporated into the bottom of a pistol grip allowing the ring finger and little finger of a shooter's hand to exert pressure on the tang, allowing increased stability, handling and therefore accuracy.

Abstract: Spacers suitable for installation between selected barrel sections of extruders are useful in evaluating the incidence of corrosion within the extruder. Processes for the deployment of such spacers are also disclosed.

Abstract: 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.

Abstract: A two-piece snap-on magazine adapter for a handgun. This magazine adapter provides a relatively continuous surface between the handgun and locked extended length magazine to afford the handgun user with a comfortable grip among other benefits. In the preferred embodiment, the magazine adapter has two snap together pieces: a main body and an end cap. The main body has an interior pocket configuration contoured to capture the magazine floor plate. The main body of the device is then captured by an end cap that locks via a detent mechanism onto the main adapter body. The magazine adapter fits completely around the magazine such that when the magazine is locked into the handgun, the resulting grip provides a smooth, continuous and comfortable fit between the extended length magazine's floor plate and the butt of the handgun's grip.
