Description
This is a traditional USGI-style 1911 magazine engineered for the compact (officer's) platform in 9mm, built with the kind of precision you'd expect from Chip McCormick Custom. What sets it apart from standard military-spec mags is the tighter manufacturing tolerances held to plus or minus .001 inch, which is more than 75% tighter than typical military specifications.
The build quality is where this mag earns its Match Grade name. You're getting a stainless steel body with enhanced feed lips that work with a stainless steel follower and aerospace-grade rocket wire spring. The welded base plate is drilled for easy customization with optional base pads. Large numbered witness holes let you count rounds at a glance without taking the mag out of your gun.
Fit and function matter when you're counting on your gun. This magazine gives you the flush-fit design that's standard for compact 1911s, so it carries without printing and seats reliably. The 8-round capacity keeps things manageable for a smaller frame while giving you what you need for carry or training. Whether you're running drills or running competition, this is the kind of magazine that just works, cycle after cycle.

Frequently Asked Questions
What's the difference between this and a standard military magazine?
The tolerances are held much tighter during manufacturing. CMC maintains plus or minus .001 inch specs, which is over 75% tighter than typical military magazines. That means better feed lip geometry and more consistent performance. You'll also get enhanced followers and aerospace-grade spring wire instead of standard coil springs.
Will this magazine fit my full-size 1911?
No, this is designed specifically for compact 1911 models like Officer's Model pistols. Compact and full-size 1911 magazines are not interchangeable. Make sure you have a compact frame before ordering.
Can I add a base pad to this magazine?
Yes. The magazine comes with a welded base plate that's drilled to accept optional CMC base pads. If you want more grip purchase or a custom look, you can add one of their pads easily.
How many rounds should I actually load it with?
While it holds 8 rounds, experienced 1911 shooters often load 7 for best spring tension and reliability over time. Load to 8 if you want the full capacity, but understand that magazine springs perform best with slightly less load.
Is this made in the USA?
Yes. Chip McCormick Custom produces these magazines domestically using in-house tooling. That precision manufacturing is a big part of why these mags have a solid reputation.
Why are the witness holes numbered?
They let you see exactly how many rounds are loaded without removing the magazine from your gun. That's useful during competitions or range sessions when you need to keep tabs on your ammunition.
