The ProMag COL02 is a straightforward replacement magazine built for the full-size 1911 Government model in .45 ACP. It holds 7 rounds, which is the traditional standard capacity for this platform and fits comfortably in the grip without protruding. The magazine body is constructed from high-carbon heat-treated blued steel and uses TIG welding for added strength. Internal components include an injection-molded polymer follower made from DuPont Zytel material and a chrome-silicon spring that's heat-treated for consistent feeding.
For anyone looking to keep spare magazines on hand without spending extra on extended capacity, the 7-round design gives you the classic 1911 configuration. The wide-cut witness holes along the side let you quickly count remaining rounds at a glance. ProMag backs these magazines with a lifetime guarantee against manufacturing defects, which is a solid commitment to stand behind the product.
Note that fit can vary depending on your specific 1911. Government and Commander frames will work with this magazine, but some users report requiring minor adjustments on certain pistol models. It's designed for frames without an external magazine well. If you have a tighter-fitting 1911, test feed before relying on it for important use.
Yes, the COL02 is designed specifically for Colt 1911 Government models and works with other Government-frame 1911s. Government and Commander frame 1911s use the same magazines. However, fit can vary slightly between manufacturers, so test-feeding is recommended before relying on it for defensive use.
Seven rounds is the traditional standard capacity for full-size .45 ACP 1911s. Eight-round and higher-capacity options exist as aftermarket or extended versions, but 7 rounds remains the classic configuration that balances capacity and reliability.
No, Officer and compact frames use shorter magazines due to their reduced grip height. This full-size magazine is designed for Government and Commander models only. Using a full-size magazine in an Officer frame may cause the mag to protrude from the grip or fail to function properly.
Chrome-silicon wire is heat-treated to resist fatigue and maintain consistent spring tension over thousands of cycles. This helps ensure reliable feeding and consistent magazine performance through extended use and storage.
ProMag stands behind these magazines against manufacturing defects with a lifetime guarantee. If you experience a defect in materials or workmanship, you can contact ProMag for replacement. This covers issues like spring failure or follower problems, not damage from misuse.
The COL02 is designed for standard 1911 frames without an external magazine well. If your 1911 has a machined magazine well or wider profile, the magazine may fit too loosely or fail to lock in place. Check your frame design before purchasing.
