The ProMag COL04 is a 10-round extended magazine purpose-built for the 1911 Government in .45 ACP, offering shooters a practical capacity boost while maintaining the classic 1911 platform's ergonomics. If you run a Government-frame 1911 and want more rounds downrange without swapping magazines, this blued steel magazine gives you the extra capacity competitive shooters, home defenders, and range enthusiasts appreciate. ProMag backs these magazines with a lifetime guarantee against manufacturer's defects, so you're covered for the life of the gun.
Built in the USA, the COL04 uses precision-wound springs made from heat-treated chrome silicon wire—the same durable wire found in premium magazines costing twice as much. Every magazine is assembled and inspected at multiple checkpoints to catch any issue before it ships, which means consistent performance and reliability you can trust when it matters.
The extended magazine fits the standard 1911 Government profile and is designed for smooth feeding and easy loading. Whether you're training at the range, competing, or building a reliable defensive setup, this magazine delivers rugged construction without the premium price tag.
