Abstract: An anti-rotation thumb rest providing advantages that allow for non-destructive and unobtrusive installation on firearms that would otherwise not be able to accommodate a thumb rests. The thumb rest may be constructed by attaching or manufacturing a long cylindrical pin onto the back side of a thumb rest, as to serve as a trigger pin, locking block pin, or other pin used for securing pistol components internally together, while also providing a typically rectangular, square, circular, or irregular shaped protrusion that serves as an anti-rotation stop for installation in a typically unused recess in the firearm's receiver, that was not expressly designed for installing components.

Abstract: An offset magazine release button includes a body portion and a generally stairstep-shaped end portion. The body portion may be inserted into a magazine release opening of a firearm. The stairstep-shaped end portion may include an indention portion providing or creating a floor or floor portion and a narrow stairstep riser. The floor, when part of the assembled firearm, is generally flush with the firearm's gripping surface to create an augmented gripping surface that may allow the operator to have a higher grip to help control recoil. The end portion also includes an offset contacting pad. The floor transitions to the riser, which then transitions to the pad. The pad has a generally perpendicular ledge or surface extending toward an actuating thumb position of the operator's grip. The pad surface may be textured to provide for better contact with the operator's thumb when depressing the button to release a magazine.

Abstract: A pack or backpack serves a dual purpose of carrying articles and offering a rapidly deployable protective garment for the wearer. The pack includes a main pack connected to a distal extension pack, with a garment concealed between them. The distal pack and garment may be simultaneously deployed by catapulting the distal pack over the wearer's head and onto their front torso to provide increased protective coverage and easier access to articles contained in the distal pack. The design of the pack provides quick access to protective garments that would otherwise take up storage room inside a compartment of a conventional pack, or be left behind when the conventional pack is carried.
