Description
This is a solid workhorse magazine for anyone running an Officer-size 1911 in 9mm. Mec-Gar has been making magazines for some of the biggest firearm manufacturers in the world since 1965, and you can tell they know what they're doing when you handle one of these.
The magazine comes with heat-treated carbon steel construction throughout, which means it's ready for regular use at the range or for carry. The nickel finish resists corrosion and looks clean, and the seamlessly welded baseplate sits flush with the grip—no wobble, no gaps. You get a high-tensile music wire spring paired with a stainless steel follower, both designed to keep rounds feeding reliably regardless of pressure or situation.
What makes this particularly useful is the witness holes along the side. You can glance at the magazine and know exactly how many rounds you're running without having to count them out. The 8-round capacity is standard for Officer-frame 1911s in 9mm, so you know it's going to work seamlessly with your pistol. People who own these magazines tend to come back for more—they're smooth to load, they drop free without hesitation, and the reliability is straightforward.
Mec-Gar magazines are OEM suppliers for major manufacturers and are used by everyone from law enforcement to competitive shooters. At this price point, you're getting the same quality that comes factory with many name-brand 1911s.

Frequently Asked Questions
Will this 1911 Officer magazine fit a full-size Government model?
No. Officer-frame magazines are shorter and are designed specifically for Officer-size (compact) 1911 pistols. Using them in a Government or Commander-frame pistol can cause reliability issues. Make sure you're ordering the right magazine for your specific frame size.
How does the nickel finish hold up over time?
Nickel-plated magazines are known for corrosion resistance and durability. The Mec-Gar nickel finish is robust enough for regular carry and use. Like any firearm component, periodic cleaning keeps it looking good, but it's low-maintenance compared to bare steel.
Are the witness holes accurate for counting rounds?
Yes. The witness holes are numbered and visible from the side of the magazine, letting you see exactly how many rounds are loaded without having to empty it out. This is genuinely useful for both range work and carry.
How do Mec-Gar magazines compare to factory magazines?
Mec-Gar actually manufactures factory magazines for many major firearm brands. These aftermarket versions use the same materials and construction methods. You're getting OEM-quality reliability without paying factory mark-up.
Will this magazine work with compact 1911s in other calibers?
No, this magazine is caliber-specific to 9mm. Officer-frame 1911s are also made in .45 ACP, .40 S&W, and 10mm, each requiring its own magazine. Always verify the caliber marking on your magazine and firearm.
