Abstract
Provided is an increased capacity firearm ammunition magazine with a metallic body. The body is dimensioned to compatibly replace a (OEM) polymer or polymer over metal single stack magazine. The body has walls with exterior dimensions compatibly matching those of the OEM magazine and that are thinner than those of the OEM magazine. The thinner walls allow an at least partially laterally offset arrangement of cartridges therein. A longitudinal exterior ridge extends along a forward wall of the body and is configured from the metallic body walls and sized to compensate for forward-to-aft dimensioning difference compared to that of the OEM magazine.
Claims37
A pistol magazine, comprising:
- a metallic tubular body defining a hollow interior and having a forward wall, a rearward wall, a first side wall, a second opposite side wall, an open top with feed lips, and an open bottom,
- a follower,
- a spring,
- a removable closure member enclosing the open bottom and removably retaining the follower and spring in the body,
- at least one spacer associated with the forward wall and extending forwardly therefrom,
- an edge associated with at least one of the side walls and configured to interact with a magazine catch of a polymer frame pistol configured to accommodate a single stack polymer or polymer-over-metal magazine,
- a first interior dimension between interior surfaces of the forward and rearward walls dimensioned to fit 9×19 mm cartridges,
- a second interior dimension between interior surfaces of the side walls dimensioned to fit 9×19 mm cartridges with a staggered arrangement of the cartridges,
- a first exterior dimension between a forwardmost surface of the at least one spacer and a rearwardmost surface of the rearward wall matching the corresponding exterior dimension of the single stack polymer or polymer-over-metal magazine,
- a second exterior dimension between exterior surfaces of the side walls matching the corresponding exterior dimension of the single stack polymer or polymer-over-metal magazine, and
- the body having a height dimension configured to fit within a handgrip of the polymer frame pistol and to locate an uppermost edge of the removable closure member directly adjacent to a lowermost edge of the handgrip when the magazine is inserted into the handgrip.
