Mec-Gar magazines are manufactured to original equipment specifications, often serving as OEM suppliers for major firearms manufacturers. The MGCO4506B features anti-friction coating on the follower and precise spring tension calibrated specifically for .45 ACP cartridges. Unlike aftermarket alternatives that may cause feeding issues, this magazine maintains the exact dimensions and tolerances required for reliable function in Officer-length 1911 platforms.
