ProMag Colt 1911 Government Model 45 ACP 10rd Magazine Nickel Plated, Extended, Polymer Grip Extension Sleeve

A ProMag Colt 1911 Government Model .45 ACP 10-round magazine with an extended polymer grip sleeve is a practical upgrade for shooters who want more ammo on tap without changing their pistol. The nickel-plated steel body is durable and corrosion-resistant, while the extended polymer grip sleeve provides a more comfortable, secure hold—especially useful if you've got larger hands or simply prefer a fuller grip profile on your .45.

This is a straightforward, no-frills magazine built for reliable feeding and longevity. The heat-treated steel construction, chrome silicon spring, and injection-molded follower work together to deliver consistent performance. It's the kind of upgrade that makes sense if your Government Model came with standard-capacity mags and you want to run a couple of higher-capacity options at the range or for self-defense scenarios where extra rounds matter.

Made in the USA, this magazine fits the standard Colt 1911 Government Model chambered in .45 ACP. The nickel plating is both a practical corrosion barrier and a classic look that complements many 1911 finishes. Whether you're building a fighting kit, extending your range sessions, or simply want a backup magazine with a better ergonomic grip, this ProMag option gives you solid performance at a reasonable price point.
