Promag
A reliable 8-round magazine purpose-built for 1911 Government models chambered in .45 ACP, the ProMag COL03 delivers the capacity and durability you need whether you're running drills at the range or carrying a platform you trust. This is a workhorse detachable magazine designed around a classic platform—straightforward, no-frills engineering that respects what 1911 shooters expect from their gear.
ProMag magazines are manufactured and assembled in the USA using heat-treated chrome silicon wire springs engineered to withstand repeated loading cycles. The construction emphasizes rugged reliability: springs are precision-wound to exacting standards, and the assembly process incorporates quality checks throughout to maintain consistency across production. You get a magazine that feeds reliably and holds up to regular use.
The COL03 features blued steel construction and is designed for easy loading so you can top off your magazine without fighting it. Whether you need a spare mag for your duty 1911, a backup for competition, or simply want redundancy in your rotation, this magazine offers the straightforward performance 1911 shooters have relied on for over a century. Backed by a lifetime guarantee against manufacturer defects, it's a no-nonsense choice for a no-nonsense gun.
