Checkmate Magazines: The OEM Behind Your 1911

Open the box on a brand-new Colt Government and pull out a magazine. Read the stamp. There's a good chance it doesn't say "Colt" — it says "Checkmate."

A lot of buyers see that and assume something is wrong. Did the dealer swap the factory mags? Is this a knockoff? Should they call somebody?

The answer is no, no, and no. Checkmate Industries is the original equipment manufacturer for many of the 1911s, M9s, and M1A rifles shipping today. The magazine is exactly what the factory put in the box. It just doesn't have the gunmaker's logo on it.

We've been selling Checkmate magazines for years across multiple platforms, and they're one of the more misunderstood brands in the business. Here's what to know: who Checkmate is, what they make, why their feed lip options matter, and how their magazines compare to the names you've probably heard more often.

Who is Checkmate Industries?

Checkmate Industries is a U.S. magazine manufacturer that started as a tool-and-die shop and won its first military contract in 1974. Today they're the largest OEM handgun magazine maker in the country, with manufacturing facilities in Long Island, New York and Thomasville, Georgia.

A few specifics worth knowing:

If you've handled a factory-issued M9 magazine in the last two decades, it was probably made by Checkmate. The company has supplied the Department of Defense's M9/92FS magazines for over 20 years on continuous contract. Same story with the M1A: Springfield Armory's factory M14/M1A magazines come out of Checkmate's facilities.

The OEM-rebrand piece is what trips people up. Colt, Springfield, Ed Brown, and a long list of other 1911 makers buy magazines from Checkmate, sometimes branded with their own logo, sometimes not. When you see a "Checkmate" stamp on a factory mag, you're looking at the same magazine the gunmaker buys — just without the rebrand.

What firearms does Checkmate make magazines for?

Checkmate's catalog is broader than most people realize. They're best known for 1911 mags, but the platform list runs long:

• 1911 (single-stack) in .45 ACP, 9mm, .38 Super, .40 S&W, and 10mm
• 2011 (double-stack 1911) in 9mm and .45 ACP
• Beretta M9 / 92FS (15-round military contract magazines)
• M1A / M14 rifles in .308 Winchester / 7.62 NATO
• Desert Eagle in .50 AE, .44 Magnum, and .357 Magnum
• Sig P365, P938, and P911
• Smith & Wesson Shield

For most shooters, the 1911 line is where Checkmate matters most. It's also the line where the feed lip question comes up — and that question is the part most buying guides skip past.

Understanding Checkmate's feed lip options

This is the section that earns Checkmate their reputation. They're one of the only manufacturers offering all three feed lip designs for the 1911 platform: GI, wadcutter, and hybrid. Picking the wrong one is the most common reason a perfectly good magazine gives somebody feeding problems.

Here's what the three styles actually do:

The GI feed lip was designed in the early 1900s around 230-grain ball ammunition, which sits at 1.26 inches overall length. Hollow points and shorter modern bullets sit closer to 1.20 inches — a 0.06-inch difference that's enough to cause inconsistent feeding when the magazine releases the round.

Wadcutter feed lips solve that problem by holding the round longer and releasing it later, which works great for short bullets but disrupts the controlled feed of traditional ball.

The hybrid is Checkmate's split-the- difference design: a slight taper that releases the round earlier than wadcutter lips but later than GI lips. For shooters who run a mix of ammo types in the same gun, hybrids are the practical answer.

If you're trying to match the feed lip to your pistol's chamber and your ammo, our team can walk you through it. We've answered this question a lot.

Checkmate 1911 magazines: 7-round vs. 8-round

The other 1911-specific decision is capacity. Checkmate makes both 7-round and 8-round magazines, and the difference matters more than the number suggests.

7-round magazines are the traditional flush-fit design — the same length and footprint as the original GI magazine the 1911 was designed around. They sit flush with the bottom of the grip, which is what you want for concealed carry or any time you don't want a magazine extending below the frame.

8-round magazines come in two flavors, and this is where buyers get tripped up. The honest version is an "extended tube" 8-round mag, which is physically longer than a 7-round to give the spring and follower proper room to cycle. The not-so-honest version is an 8-round mag that uses a 7-round body with a stiffer spring and a thinner follower to squeeze in an extra round. Those work — sometimes — until they don't.

Checkmate's 8-round magazines are the extended-tube design. They run reliably because the geometry is right — not because Checkmate is muscling an extra round into a smaller envelope.

We carry a range of 1911 magazines including Checkmate options across both capacities and all three feed lip styles, in stainless and blued finishes.

How Checkmate compares to Wilson, Tripp, and Mec-Gar

If you've spent any time on 1911 forums, you've seen the debates. Here's the honest version, from somebody who sells all of them:

There's no single "best" 1911 magazine. There's the magazine your specific gun runs best with the ammo you're actually feeding it. For most shooters, Checkmate is the value option that doesn't require giving anything up. For shooters who want to optimize past that point, Wilson and Tripp are worth their premium.

M9, M1A, and other platforms

The 1911 is the headline, but Checkmate's reputation across other platforms is worth knowing about.

Beretta M9 / 92FS magazines. These are the same 15-round mil-spec magazines Checkmate has been supplying to the Department of Defense for more than 20 years. Commercial buyers can get the exact same magazine without the contract markings. For a working M9 or 92FS, this is what runs in service rifles — it'll run in yours.

M1A / M14 magazines. Springfield Armory's factory M1A mags come from Checkmate. So do many of the surplus M14 magazines that have been in U.S. service for decades. If you own an M1A, the OEM magazine is a Checkmate, branded or not.

Newer subcompacts (P365, Shield). This is where feedback gets mixed. Some users report flawless function with Checkmate magazines for the P365 and similar subcompacts. Others report intermittent issues. The platforms are newer, the tolerances are tighter, and Checkmate's track record on subcompact mags isn't as long as their 1911 or M9 history. We'd call this the area where Checkmate is still earning its reputation rather than coasting on it.

What to look for when buying Checkmate magazines

A few practical notes if you're shopping:

Match the feed lip to your ammo. This is the biggest single decision. If you don't know what feed lip you have, look at the box or the listing. If you're not sure, ask. Most retailer listings don't make this clear, which is part of why Checkmate's reputation is uneven — people end up with the wrong feed lip for their use case and blame the magazine.

Stainless vs. blued is mostly cosmetic. Both materials work. Stainless resists corrosion better and shows finger marks less. Blued looks more period-correct on a traditional 1911. Pick whichever fits the gun.

Removable baseplate vs. welded. Most modern Checkmate 1911 magazines have removable baseplates so you can disassemble for cleaning. Older designs and some specific mil-spec versions are welded. For range and carry use, removable is easier to maintain.

Note the follower. Checkmate's CMI follower is a captive design that resists tilt. It comes standard on their 8-round magazines and stainless 7-rounders. Older flat-top GI followers are still fine for traditional ball-only setups but less forgiving with mixed ammo.

A note about buying direct: Checkmate's own website is set up for OEM business, not retail. Spec details are sparse, and shipping isn't their strong suit. You're better off buying through retailers who list the feed lip type, capacity, finish, and follower style clearly — and who can answer questions if something doesn't look right.

If you walk into a 1911 forum thread that says "Checkmate sucks," there's a decent chance the writer ordered the wrong feed lip or got an older configuration that doesn't match their ammo. The magazines themselves are well-made. The buying process just rewards customers who know what they're asking for.

Wrapping up

Checkmate Industries has been making magazines longer than most of the gunmakers they supply have been in business. Their pedigree is the OEM contracts and the military service record, not the marketing budget.

Here's what to take away:

We sell Checkmate magazines across most of the platforms above, and we carry the broader 1911 magazine selection so you can compare options. Stock varies, so check the site for what's available now.
