Description
This is a workhorse magazine engineered for the Staccato 2011 and other double-stack 1911 platforms like the Springfield Prodigy. Check-Mate engineered it with the same precision that's expected from OEM-grade components, but you're getting a magazine that works across multiple compatible platform builds.
The tube is American-milled stainless steel and through-hardened for exceptional durability. What really matters for you is the fit and function: both the inside and outside surfaces are polished to minimize drag as rounds strip from the magazine and feed into the chamber. This attention to surface detail makes a real difference when you're running multiple reloads in rapid strings or pushing the gun hard in competition.
The follower is the real story here. Check-Mate designed a self-lubricating polymer follower that keeps friction low and keeps rounds stacking consistently, which translates to reliable feeding on every shot. Paired with their high-performance spring, you get consistent tension that doesn't go dead after hundreds of rounds. At 15 rounds in 10mm from a 126mm tube, this magazine hits that sweet spot between capacity and manageable size.
If you run a Staccato 2011, Springfield Prodigy 1911 DS, Kimber 2K11, or other compatible double-stack 1911, this is a solid spare or replacement magazine for range time, training, or competition. Numbering your mags with a marker and cycling them helps you identify any that need cleaning or spring maintenance down the line.

Frequently Asked Questions
Will this magazine work with my Springfield Prodigy or other 2011 clone?
Yes. This Check-Mate magazine is specifically engineered to fit the Staccato 2011, Springfield Prodigy 1911 DS, Kimber 2K11, EAA Witness 2311, and other compatible double-stack 1911 platforms. Just make sure your gun uses the 126mm magazine body length. Some models may vary, so it's worth confirming compatibility before purchase.
How does the 126mm length affect grip and handling?
At 126mm, this magazine is slightly shorter than full-length double-stack mags but longer than reduced capacity options. It balances maximum capacity with reasonable grip feel. The magazine won't make your gun harder to carry or conceal compared to standard 17 or 19-round magazines, but it does give you solid capacity for competition and range work.
What maintenance does this magazine need?
Periodically disassemble it for cleaning by depressing the basepad, sliding it forward, and removing the follower and spring. Wipe out any carbon build-up with a dry cloth and inspect the follower for damage or deformation. Don't use oils inside the magazine tube. If you shoot competitively or run high round counts, numbering your mags helps you spot any that need attention.
Why is the finish polished instead of matte?
The polished interior and exterior surfaces reduce friction and drag as ammunition feeds. This smooth surface helps rounds strip cleanly from the magazine and feed reliably into the chamber, especially during rapid strings or extended shooting sessions. The polished finish also makes the magazine easier to clean.
Can I use this 15-round magazine with standard single-stack 1911 magazines or parts?
No. This is a double-stack magazine designed specifically for 2011-platform firearms. It uses different geometry, feed lips, and follower design than traditional single-stack 1911 magazines and is not compatible with them.
