Match Grade stainless steel magazines are the original extra capacity 1911 mags dating back to 1986. These magazines are flush fitting for the best concealability and least hindrance with clothing. Match Grade mags are 100% designed by CMC and built in the USA, to the same exacting tolerances, with the same heavy duty construction and materials the Power Series. Feed lip geometry and overall design achieves increased reliability, service life, and function with a broader selection of ammunition, and "Rocket Wire" springs provide for increased reliability. The stainless steel base plate is welded flush, and pre-drilled to accept CMC's optional screw-on base pads. This Match Grade mag has a 7-round 45 ACP capacity and is compatible with most popular compact 1911-style pistols. It includes CMC's screw-on base pad designed for competition shooters with extended mag wells to give them extra material on the bottom of the magazine for assisting with positive insertion and seating of the magazine into the pistol.
