Claims (30)

1. An ammunition magazine comprising:

a body comprising a magazine catch;

a follower engaged with a spring and a floorplate retainer;

a floor plate engaged with the floorplate retainer and the body; and

a metal insert, wherein the metal insert is positioned on an upper portion of an interior of the body, wherein the metal insert comprises a magazine catch extension, and wherein the magazine catch extension bends outward away from the body to reinforce the magazine catch.

2. The ammunition magazine of claim 1 , wherein the body is a polymer.

3. The ammunition magazine of claim 1 , wherein the body is a metal or an alloy.

4. The ammunition magazine of claim 1 , wherein the metal insert comprises a first and a second upper lip, and wherein the first and second upper lips are positioned on an interior portion of a magazine body set of lips.

5. The ammunition magazine of claim 4 , wherein the first and second upper lips include a curvature, and wherein the curvature of the first and second upper lips matches a curvature of the magazine body set of lips.

6. The ammunition magazine of claim 5 , wherein the metal insert further comprises a first side and a second side engaged with a rear side, wherein the first and second upper lips are positioned at an upper portion of the first and second sides, and wherein the rear side is positioned adjacent to a rear portion of the body.

7. The ammunition magazine of claim 6 , wherein a height of the first and second sides is greater than a height of the rear side.

8. The ammunition magazine of claim 7 , wherein the rear side includes at least one orifice.

9. The ammunition magazine of claim 8 , wherein the first and second sides include a plurality of orifices, wherein the plurality of orifices each include an area that is smaller than an area of the at least one orifice on the rear side.

10. The ammunition magazine of claim 1 , wherein the metal insert includes a height, wherein the height of the metal insert exceeds a height of the follower.

11. The ammunition magazine of claim 1 , wherein the metal insert magazine catch extension is positioned adjacent to the magazine catch.

12. The ammunition magazine of claim 11 , wherein the magazine catch is positioned on a first side of the metal insert, wherein the first side of the metal insert includes a height, and wherein the first side of the metal insert height is greater than a height of a second side of the metal insert.

13. The ammunition magazine of claim 1 , wherein at least a portion of the metal insert is overmolded with the body.

14. An ammunition magazine comprising:

a body comprising a magazine catch, wherein the body is formed of a polymer; and

an insert, wherein the insert is positioned on an upper portion of an interior of the body, wherein at least a portion of the insert is overmolded by the upper portion of the body, wherein the insert comprises a magazine catch extension, and wherein the magazine catch extension bends outward away from the body to reinforce the magazine catch.

15. The ammunition magazine of claim 14 , wherein the insert is a metal or an alloy.

16. The ammunition magazine of claim 15 , wherein the insert further comprises a pair of sides engaged with a rear side, wherein the rear side is positioned adjacent to a rear portion of the body.

17. The ammunition magazine of claim 16 , wherein the magazine catch extension is positioned adjacent to the magazine catch.

18. A method of making an ammunition magazine comprising:

implanting an insert in a magazine body mold, wherein the insert is a metal or alloy;

injecting a polymer in the magazine body mold;

overmolding at least a portion of the insert with the polymer; and

forming a magazine body wherein the magazine body comprises a magazine catch, wherein the insert is positioned on an upper portion of an interior of the magazine body, wherein the insert comprises a magazine catch extension, and wherein the magazine catch extension bends outward away from the magazine body to reinforce the magazine catch.

19. The method of making the ammunition magazine of claim 18 , wherein the insert comprises a pair of sides engaged with a rear side, wherein the rear side is positioned adjacent to a rear portion of the magazine body.

20. The method of making the ammunition magazine of claim 19 , wherein the magazine catch is configured to engage the magazine catch extension.
