Mec-Gar MG-CG4511B 11-Round Magazine for Colt Government 45 ACP, Blue Finish

The Mec-Gar MG-CG4511B is an 11-round magazine for Colt Government .45 ACP pistols, built with the kind of durability and reliability you expect from one of the industry's most trusted magazine manufacturers. If you shoot a Government-pattern 1911 in .45 and want a reliable spare or backup mag that actually fits and feeds without fuss, this is a no-nonsense choice backed by decades of OEM and aftermarket production.

Mec-Gar magazines are engineered for real-world use—the tube is carbon steel, heat-treated for strength, and the spring is music wire that holds up through thousands of cycles. The welded butt-plate won't rattle loose or come apart at the range or in the field, and the blue finish resists corrosion while keeping that classic look. An 11-round capacity in .45 ACP gives you extra rounds on tap compared to standard 7-round single-stack mags without requiring a rebuild or exotic platform—just load it and go.

Whether you're stocking spares for carry, building a range kit, or just want magazines you can trust to feed when it matters, the Mec-Gar approach is straightforward: strong materials, proven design, no hype. It fits Colt Government and compatible .45 ACP single-stack pistols.
