1. A method of manufacturing a pistol magazine, comprising:
forming 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,
forming at least one longitudinally extending spacer on the forward wall projecting forwardly therefrom,
forming an edge on at least one of the first and second side walls configured to interact with a magazine catch of a polymer frame pistol configured to accommodate a single stack polymer or polymer-over-metal magazine,
providing a removable closure member for enclosing the open bottom of the body,
wherein the step of forming the body further comprises:
forming a first internal dimension between the forward wall and the rearward wall dimensioned to fit a selected caliber of cartridge,
forming a second internal dimension between the first side wall and the second side wall dimensioned to fit the selected caliber of cartridge with a staggered arrangement of the cartridges,
forming the body to have a height dimension configured to fit within a handgrip of the polymer frame pistol and locate the removable closure member directly adjacent to the bottom of the handgrip when the removable closure member is installed on the bottom of the body and the magazine is inserted into the handgrip of the polymer frame pistol,
forming the body to have a first external dimension of the body from a forwardmost surface of the spacer to the rearwardmost surface of the rearward wall matching the corresponding exterior dimension of the single stack polymer or polymer-over-metal magazine, and
forming the body to have a second external dimension of the body from the external surface of the first side wall to the external surface of the second side wall matching the corresponding exterior dimension of the single stack polymer or polymer-over-metal magazine,

providing a follower,
installing the follower in the body,
providing a spring,
installing the spring in the body, and
installing the removable closure member on the open bottom of the body.
