This is a 10-round .45 ACP Kimber Ten II magazine from MecGar. Constructed out of heat-treated carbon steel with a special anti-friction coating, these Kimber Ten II 10-round magazines are built for lasting service and corrosion resistance in harsh and demanding environments. The high-tensile music wire spring and high-impact polymer follower ensure optimal cartridge alignment and smooth, reliable feeding in high-stress target shooting and defensive situations. Plus, the impact-resistant polymer baseplate sits flush with the pistol for comfortable carry and a smooth, snag-free draw.
