Manufacturer: Chip McCormick 14110
Chip McCormick Match Grade stainless steel magazines are the only fully featured, stocklength, fixed base magazines available for 1911 handguns. Match Grade mags are made to the same exacting tolerances as the high end Power Mag series. That means the die controlled tolerances are held to +/- .001 inches (over 75% tighter tolerances than the Military Specifications used by our competitors).
