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.
