Colt Firearms 1911 Magazine Features The Colt 1911 Combat Officer Magazine is machined from stainless steel giving it the strength and corrosion resistance needed for a magazine that sees repeated loading and unloading. A high-performance steel spring maintains its tension over time ensuring reliable feeding throughout the full 10-round capacity. The flat follower design promotes smooth consistent cartridge presentation into the feed lips reducing the chance of feeding malfunctions. Machined witness holes along the magazine body let shooters visually confirm remaining round count at a glance. A factory-installed polymer bumper pad protects the base of the magazine during hard reloads and drops extending the magazine s service life. That same bumper pad helps guide the magazine into the well during a fast reload reducing fumbling under pressure. Built specifically for the 1911 Combat Officer platform in 9mm Luger this magazine is a proper factory fit rather than a generic aftermarket option. Colt designed this magazine as a dependable spare or replacement for 1911 Combat Officer owners running 9mm.
