Mec-Gar has been quietly building magazines for many of the world's top firearm brands since 1965, so when you pick up one of their 1911 mags you're getting the same quality that ships inside plenty of factory pistols. This one is the MGCG4510A, a 10-round extended magazine made specifically for full-size 1911 Government and Commander frames chambered in .45 ACP. The extended tube gives you two more rounds over a standard flush-fit mag, so it hangs a touch below the frame, which is the trade-off for the added capacity.
The build is straightforward and proven. You get a heat-treated carbon steel tube for strength, a high-impact polymer follower that feeds clean, and a high-tensile music wire spring that keeps consistent pressure on the stack. The floorplate is polymer with a built-in shroud that stops the mag from over-inserting, and the whole body wears Mec-Gar's anti-friction coating.
That coating isn't just marketing. It slicks up every surface so rounds load easier, the mag drops free clean, and grit has a harder time causing hiccups. It also adds a layer of rust resistance, which matters if this mag rides in a range bag or spends time as a spare in the glovebox. Folks who run these report smooth, reliable feeding across different 1911 models, and Mec-Gar's reputation for building a dependable mag at a fair price is well earned among people who shoot the platform regularly.
Whether you want extra capacity for a long range session, a backup for competition, or just a solid spare to keep loaded at home, this is an easy call. It's a genuine Mec-Gar built to real tolerances, and one heads-up worth knowing: a fresh mag spring can be stiff at first, so that tenth round may take a little muscle until it breaks in.
It's designed for full-size 1911 Government and Commander pistols chambered in .45 ACP, including Colt and many other 1911-pattern guns built to standard spec. Because it's an extended 10-round tube, it will hang slightly below the frame rather than sit flush. If your 1911 uses standard-size magazines, this one should drop right in.
A brand-new magazine spring is at its stiffest before it settles in, so getting that last round seated can take a little extra thumb pressure at first. This is normal and eases up after the spring breaks in with use. A speed loader can save your thumbs during that break-in period if you're loading a lot of mags.
Mec-Gar has built OEM magazines for major firearm makers since 1965, and the platform has a strong reputation for smooth, consistent feeding across different 1911 models. The heat-treated steel tube, polymer follower, and music wire spring are proven components. Plenty of owners trust these as spares and dependable everyday mags.
It reduces friction on the magazine surfaces so rounds load easier, the mag drops free cleanly, and there's less chance of grit causing a malfunction. It also adds corrosion resistance, which helps if the mag lives in a range bag or gets exposed to moisture. It's a practical upgrade over a plain finish.
