Description
When you carry a compact .45, the last thing you want is to wonder whether an aftermarket magazine is going to run right. This is EAA's factory magazine for the MC1911SC, built to the same specs and tolerances as the one that shipped with the pistol. There's no guessing about fit or compatibility.
The body is steel with a black finish, keeping things simple and durable. A flush-fitting steel baseplate keeps the profile clean for carry, with no protrusion to snag on a holster or cover garment. Inside, a high-tensile spring and flat steel follower work together to feed reliably and keep rounds in the right position from the first round to the last. The 6-round capacity is standard for officer-length 1911s in .45 ACP, and that compact length is a big part of what makes the MC1911SC a practical carry gun in the first place.
The MC1911SC sits in officer or subcompact 1911 territory, and this magazine is also noted to be compatible with most other compact and officer-size 1911 pistols chambered in .45 ACP. So if you've got other guns in that class, it may serve double duty.
Most MC1911SC pistols ship with a single magazine, which means picking up at least one or two spares is just practical planning. Running a backup through a range session before trusting it for carry is always a good habit, and having a factory mag makes that a lot easier to feel good about.

Frequently Asked Questions
Will this magazine work in my Girsan MC1911SC?
Yes, this is the factory magazine designed specifically for the MC1911SC chambered in .45 ACP. It's built to the same specifications as the magazine that ships with the pistol, so fit and function should be right on the money. No fitting or modification should be required.
Can I use this magazine in other 1911 pistols?
This magazine is primarily intended for the Girsan MC1911SC, but it is also noted to be compatible with most other officer-size and compact 1911 pistols chambered in .45 ACP. That said, magazine compatibility can vary between makes and models, so it's worth testing any new magazine through a full function check before carrying it.
Why does the MC1911SC use a 6-round magazine instead of 7?
The MC1911SC is an officer-length 1911, which uses a shorter grip frame than a Commander or Government model. The 6-round capacity is standard for that platform in .45 ACP and is part of what keeps the gun compact enough for everyday carry. Some 7-round extended options exist, but they will typically add length below the grip.
Is this a true factory Girsan magazine or a third-party replacement?
This is a genuine EAA/Girsan factory magazine carrying the MPN 390502 and distributed by European American Armory. It is not an aftermarket or third-party product, which means it is built to the same tolerances as the original magazine included with the MC1911SC.
How many magazines does the MC1911SC come with from the factory?
Most MC1911SC pistols ship with a single magazine. Picking up one or two spares is a practical move, especially if you plan to use the gun for carry or take it to the range regularly. Having a backup already loaded saves time and gives you a way to quickly identify whether a malfunction is mag-related or gun-related.
