CMC Products 17150 Power Mag Railed 10rd 45 ACP Fits

CMC Products’ RPM or Railed Power Mags are the strongest 1911 magazines ever made. The RPM design is the result of a relentless pursuit of excellence, maximizing reliability and durability under all conditions. The dual wall feed rails have revolutionized 1911 magazines. The feed rails built into the RPM are at lest twice as strong as any traditional 1911 magazine feed lips and provide the smoothest feeding surface.
