Mec-Gar 1911 Officer .45 ACP 7-Round Nickel Magazine (MG-CO4507NPF)

The Mec-Gar 1911 Officer .45 ACP 7-round nickel magazine is a reliable, purpose-built feed solution for compact 1911 pistols and Officer-model platforms. If you carry or shoot a 1911 Officer in .45 ACP, this magazine delivers the capacity and dependability you need without oversizing your grip. Mec-Gar has been manufacturing OEM magazines for decades, and this piece reflects that heritage: solid engineering, proven materials, and attention to detail that shows up on the range and in the field.

Built from heat-treated carbon steel, the tube is engineered to withstand repeated chambering and ejection cycles. The follower is a lubricated nylon polymer design with a metal insert positioned to ensure the slide stop catches reliably every time—no guessing, no feeding hiccups. The spring uses higher-tensile music wire with a phosphate coating, which not only handles the abuse but also makes manufacturing more consistent. The removable butt-plate is tapered to sit flush in funneled mag wells, so it seats cleanly without rocking or binding. Internal components are linked for straightforward field disassembly and reassembly, letting you swap springs or clean without special tools.

Nickel plating resists corrosion better than bare steel, a practical choice if your magazines live in a range bag or duty rig. At 7 rounds, this magazine matches the compact footprint of Officer-frame 1911s—no printing, no awkward overhang—while giving you a solid reload capacity. Whether you're running defensive drills, hunting, or just stocking spares, a quality 1911 Officer magazine is non-negotiable. This Mec-Gar offering is the real deal.

Frequently Asked Questions

Will this magazine fit my 1911 Officer-frame pistol?

Yes, this magazine is designed for 1911 Officer-frame models in .45 ACP. The tapered butt-plate is engineered to seat in funneled mag wells typical of Officer platforms. If you're unsure about your specific pistol, verify it accepts Officer-size magazines before ordering.

What makes Mec-Gar magazines different from other aftermarket options?

Mec-Gar manufactures OEM magazines for major firearm brands and brings that same precision to their branded line. This magazine uses heat-treated steel, quality music-wire springs, and a follower design optimized for reliable feeding and slide-stop function—features you'll use hundreds of times without thinking about it.

Can I take this magazine apart to clean or replace the spring?

Yes. The internal components are linked together to allow easy disassembly and reassembly without special tools, making maintenance and spring replacement straightforward.

Does the nickel finish affect reliability?

No. Nickel plating is purely a corrosion-resistance upgrade; it doesn't interfere with feeding or function. It's an especially practical choice if your magazines spend time in a range bag or get exposed to moisture.
