The Mec-Gar 1911 Officer magazine handles seven rounds of .45 ACP in a compact footprint designed specifically for Officer-size and compact 1911 pistols. This is the mag to grab when you need one extra round without adding bulk to your carry gun or range setup.
What makes this magazine stand out is the attention to detail in every component. The tube is heat-treated carbon steel with a nickel finish for corrosion resistance. The spring uses high-tensile music wire with a phosphate coating, giving you reliable feeding that holds up through hundreds of cycles. The lubricated nylon polymer follower includes a metal insert for proper interaction with the slide stop, so your last round actually locks the slide back like it should.
The removable high-impact polymer buttplate is a practical feature. It tapers to fit funneled magazine wells, making it work with a range of pistols, and you can swap it out for a grip extension or leave it off for tighter concealment. The numbered witness holes at rounds 2 through 7 let you do a quick round count without unloading. Mec-Gar has been making magazines since 1965, with over 100 million produced across military and police use globally, so you're looking at field-proven design and manufacturing standards.
No, this is specifically designed for Officer and compact frame 1911 pistols. Full-size 1911s require full-size magazines. Compact frames measure 2.6875" center-to-center between grip screws, while full-size frames are 3.0625". Using the wrong size can cause feeding issues.
This magazine holds 7 rounds of .45 ACP ammunition. Most standard Officer compact magazines hold 6 rounds, so this gives you an extra round while maintaining the compact profile.
Yes, the buttplate is removable and removable for a reason. You can take it off for tighter concealment, swap it for a grip extension for easier loading, or add a custom base pad. It's held on with a simple push pin.
Both finishes offer corrosion resistance, but nickel provides enhanced protection in adverse conditions and has a polished appearance. Blued is more traditional and still durable. Functionally, they perform identically.
The holes on the side are numbered 2 through 7, so you can see at a glance how many rounds are loaded without taking the magazine apart. This is useful for quickly confirming capacity during range sessions or maintenance.
Yes. Mec-Gar has been manufacturing magazines since 1965 and has produced over 100 million units for military and police agencies worldwide. They produce OEM magazines for major firearm manufacturers, so the quality and reliability are well-established.
