Description
If you've shot 1911s for any length of time, you know magazines are where reliability happens. This Colt factory mag is built the same way the originals are, using the same specifications that have worked for over a century. Stainless steel construction keeps corrosion out of the picture whether you're running it wet or dry, and the 7-round capacity gives you the standard load that the platform was designed around.
Fits Government and Commander Equally
One of the nice things about 1911s is that Government and Commander models share the same grip frame, which means they take the same magazines. Load this mag into either platform and it seats flush with the same snug fit you'd expect from factory parts. It also works in Gold Cup and Double Eagle models, so if you have multiple 1911s in your safe, these cover the bases.
Built to OEM Standards
This isn't an aftermarket mag trying to be something it's not. Colt makes these the same way they did decades ago, with proper spring tension and a flat follower for smooth feeding. Users report clean feeds and extractions without the binding or catch issues that sometimes show up with lesser alternatives. The stainless finish resists wear and corrosion, so these mags hold up through years of use without degrading.
A Practical Setup
Seven rounds is the baseline for a reason. The 1911 was engineered with this capacity in mind, and it functions flawlessly with it. A single magazine works for range days, training, or carry setups. Most people run multiple mags as backups or spares, and having quality Colt originals in rotation means one less thing to worry about when you need it to work.

Frequently Asked Questions
Will this magazine work in both Government and Commander models?
Yes. Government and Commander 1911s share the same grip frame, so they use identical magazines. This mag works in both platforms, as well as Gold Cup and Double Eagle models chambered in .45 ACP.
Can I use a 7-round magazine if my 1911 came with an 8-round mag?
Absolutely. The 7-round is the standard capacity the 1911 was designed for and functions reliably in all full-size 1911s. Many shooters prefer 7-rounders for their straightforward operation and proven track record.
How does stainless steel construction benefit a magazine?
Stainless steel resists corrosion from moisture and use, so the magazine maintains its finish and function over years of service. It also resists rust better than blued steel in humid or wet conditions, making it a good choice for carry or storage.
Is this an OEM Colt magazine or aftermarket?
This is a factory Colt original made to their OEM specifications. It's built using the same materials and standards as the magazines that ship with Colt 1911 pistols, ensuring proper fit and function.
