Abstract:
A magazine for use in a firearm includes first and second feed lips having folded portions to reinforce the strength of the respective feed lips. In some embodiments, the strength of the feed lips may be further reinforced by applying one or more welds. The feed lips are capable of withstanding greater amounts of force to avoid failure. Accordingly, the disclosed magazine and method for providing the magazine reduce the “spring back” effect present in conventional magazine feed lips. This removes the additional step of having to over-form the feed lips that is performed when forming a magazine having conventional feed lips. The result is a method for providing a magazine with folded feed lips that are capable of withstanding greater amounts of force to avoid warping, deforming, or other failure, wherein the method for forming the magazine is more accurate, more consistent, and involves fewer steps.

Claim (Index 25):
A cartridge retention system for use in a magazine, the cartridge retention system comprising:\n a housing having an opening and operable to retain one or more cartridges in an interior portion of the magazine; a first feed lip coupled to and integral with the housing at the opening of the housing, wherein the first feed lip includes a first folded portion, wherein the first feed lip is folded toward the interior portion of the magazine and operable to retain the one or more cartridges in the magazine at desired lateral and vertical positions; a second feed lip coupled to and integral with the housing at the opening of the housing, wherein the second feed lip includes a second folded portion, wherein the second feed lip is folded toward the interior portion of the magazine and operable to retain the one or more cartridges in the magazine at the desired lateral and vertical positions; and a follower disposed in the interior portion of the magazine and operable to bias the one or more cartridges towards the opening of the housing, the follower comprising an engagement member having one or more protrusions operable to engage an annular recess of one of the cartridges to retain the engaged cartridge at a desired horizontal alignment.
