US12332006 - Firearm magazine retention system with positive positioning feature

A firearm magazine retention and release system providing a motion-limiting engagement between a firearm and a magazine. The magazine is provided with a catch opening. The firearm is provided with a magazine catch having a protrusion positioned to engage the catch opening. The protrusion includes one or more sloping surfaces that provide a greater vertical engagement as the protrusion is urged further into the catch opening. The result is that the protrusion engages one or more edges of the catch opening—thereby inhibiting vertical travel of the magazine with respect to the firearm.

firearmmagazineretentionsystem

The patent describes a magazine retention and release system that utilizes a tapered protrusion on the firearm’s magazine catch to securely engage with a catch opening in the magazine, preventing vertical movement. This design enhances the stability of the magazine by ensuring a fixed position through a spring biasing mechanism and camming action of the tapered surface against the magazine edges.

Claim 1

A magazine retention and release system for retaining a magazine having a magazine catch opening in a firearm, comprising: (a) a magazine catch attached to said firearm, said magazine catch having a protrusion protruding toward said magazine; (b) said protrusion having a tapered surface, with said tapered surface causing a width of said protrusion to diminish when proceeding in a direction toward a center of said magazine; (c) a spring biasing said protrusion of said magazine catch toward said center of said magazine; and (d) wherein said tapered surface bears against an edge of said magazine catch opening, thereby camming said magazine to a fixed position in which said protrusion bears against said first edge of said magazine catch opening and a second edge of said magazine catch opening. (a) a magazine catch attached to said firearm, said magazine catch having a protrusion protruding toward said magazine; (b) said protrusion having a tapered surface, with said tapered surface causing a width of said protrusion to diminish when proceeding in a direction toward a center of said magazine; (c) a spring biasing said protrusion of said magazine catch toward said center of said magazine; and (d) wherein said tapered surface bears against an edge of said magazine catch opening, thereby camming said magazine to a fixed position in which said protrusion bears against said first edge of said magazine catch opening and a second edge of said magazine catch opening.
