Abstract: An improved magazine follower for use in existing magazines such as a 30 round magazine comprises a follower plate, a base plate, and a spring. The follower plate comprises a top plate, a convex follower leg, and a concave follower leg. The external shapes of the top plate, the convex follower leg, and the concave follower leg mirror the interior profile of the magazine, constraining the motion of the follower plate to a well-defined path within the magazine. The method of attaching the spring to the follower plate and the base plate in addition to the shape of the spring keeps the spring from “wobbling” or moving off a vertical axis of the spring as rounds of ammunition are loaded or dispensed. Consequently, the present system reduces binding or jams within the magazine, improving performance and life of the magazine follower.

Abstract: A stand secures a loaded firearm in an inoperable condition for quick release to an authorized user in the event of an emergency. A housing serves as a base for the stand. A mechanism fixed to the housing prevents the firearm from firing. For example, a rod fixed to the housing is inserted through the muzzle and into the bore until it extends into an empty chamber of a revolver or into the receiver of an automatic pistol. Another mechanism mounted on the housing is operable between a first position in which it permits engagement of the firearm on and disengagement of the firearm from the rod and a second position in which it prevents disengagement of the firearm from the rod. The operating mechanism may be actuated manually by a key or electronically by a key pad, a fingerprint recognition pad or the like.

Abstract: The present invention is a spring-biased folding firearm that stows compactly and safely. The firearm has three main components: a stock, a receiver and a grip/magazine combination. In folding, the stock folds over the receiver, sandwiching the grip/magazine between the components. When folded, the magazine over-inserts into the grip housing, allowing the stock to clear and providing additional safety when stowed by isolating the ammunition feed. A buttplate latches over the open joint to contain the unit and further secure it. When stowed, the bolt is disengaged from the ammunition feed supply, preventing accidental firing, so a loaded round can be safely carried in the chamber—allowing for immediate use of the firearm upon opening. The weapon is deployed through single-handed actuation and is spring-assisted into firing position. Currently the firearm uses readily available aftermarket parts for easier replacement if necessary and does contain hardware for mounting accessories.
