Description

This Mec-Gar 11-round magazine gives your 1911 a one-round capacity boost over standard seven-round mags. Built with the same precision that major manufacturers rely on, it works with Colt, Kimber, Springfield, Smith & Wesson, and other full-size 1911 pistols.

The construction is what sets this mag apart. You get a heat-treated carbon steel tube welded for strength, a high-tensile music-wire spring that maintains tension through heavy use, and a steel follower designed for consistent feeding. The welded baseplate adds durability and provides some protection during tactical mag changes or range sessions. Witness holes on both sides let you quickly check your round count without unloading.

Mec-Gar has been making magazines for military and law enforcement since 1965, and their OEM contracts with major firearms brands speak to their manufacturing standards. This isn't a bargain-basement mag, but it won't break the bank either. Field reports show these mags feed reliably with standard hardball loads and deliver smooth, positive lockup in the magazine well.

Frequently Asked Questions

Will this 11-round magazine work with my 1911?

Yes, if you have a full-size 1911 Government or Commander model. It's confirmed compatible with Colt, Kimber, Springfield, Smith & Wesson, and Sig GSR platforms. Some owners report it also works with Remington R1, Ruger, and a few custom 1911 builds, but fit can vary with less common brands.

How does an 11-round magazine compare to the standard capacity?

Standard 1911 magazines hold seven rounds. This extended-capacity mag adds four extra rounds without changing the firing mechanics of your pistol. The longer baseplate hangs below the grip, which is why you get the extra capacity.

What makes Mec-Gar magazines reliable?

Mec-Gar manufactures OEM magazines for major brands like Springfield Armory, Browning, Remington, and Sig Sauer, which means they meet strict military and law enforcement standards. The heat-treated carbon steel body, high-tensile spring, and precision welding hold up to sustained use and temperature extremes.

Is this magazine easy to load?

Yes. The high-tensile music-wire spring resists excessive binding while staying stiff enough for reliable feeding. Most users report smooth, consistent loading without hand fatigue, and the witness holes help you track how many rounds you've loaded.

Can I clean and maintain this magazine myself?

Absolutely. The welded baseplate is removable for easy disassembly and cleaning. The magazine body has no complex internal parts, just the spring and follower, so routine maintenance is straightforward.

How long will this magazine last?

Mec-Gar mags are known for long service life. The heat-treated steel resists denting and deformation that softer aftermarket magazines suffer from. Users report trouble-free function after years of regular range use and storage.
