Description
The Global Ordnance Glock-style .45 ACP magazine gives you a serious capacity boost without sacrificing reliability. At 26 rounds, you're looking at over double the standard Glock 21 factory capacity, which means less time reloading and more time at the range or training.
Construction-wise, these are solid. Each magazine features a hardened steel insert encased in high-tech polymer that resists deformation even when dropped. That polymer shell is built to withstand field use without falling apart or deforming under stress. The design mirrors what Glock uses in their factory magazines, so you get familiar ergonomics and proven function.
The magazine includes witness holes along the back so you can quickly see how many rounds remain without emptying it. A high-visibility polymer follower keeps rounds properly aligned during feeding and makes reloading easier to gauge. These are made in South Korea and have earned respect among folks looking for affordable extended-capacity options.
Keep in mind that extended magazines of this capacity can be a bit stiff to load when brand new. Most owners find they break in smoothly after a few loadings. They work with Glock 21, 30, and 41 double-stack .45 ACP pistols, and also function with compatible .45 ACP platform rifles.

Frequently Asked Questions
Will this magazine work with my Glock 21?
Yes. This magazine is specifically designed for Glock 21, Glock 30, and Glock 41 pistols. It also works with compatible .45 ACP platform rifles and carbines. This is not an official Glock product, but it fits and functions with the standard Glock pattern mag well.
How difficult is it to load 26 rounds?
New extended magazines of this capacity tend to have stiff springs, so initial loading can require some force. Most owners report they break in noticeably after a few loadings and use cycles. A magazine loader or speedloader makes the process much easier if you're doing it frequently.
Is this magazine as durable as a factory Glock magazine?
Yes. The construction is nearly identical to factory Glock magazines, featuring a hardened steel insert inside a durable polymer body. The polymer is designed to resist deformation even from drops and rough handling. The big difference is this is a third-party product, not manufactured by Glock.
How do the witness holes work?
Numbered holes run along the back of the magazine, allowing you to see at a glance how many rounds remain loaded. This is the same feature found on factory Glock extended magazines and is useful for quickly assessing capacity without removing the magazine.
What do I do if the follower gets damaged or cracked?
The high-visibility polymer follower can be replaced separately if needed. However, they're quite durable in normal use. If you experience feeding issues early on, ensure the magazine is fully broken in with multiple load cycles before concluding there's a problem.
Will this magazine work with my .45 ACP AR-15 or PCC?
Yes, it will function with most .45 ACP pistol caliber carbines and AR-15 uppers that accept standard Glock-pattern magazines. Verify compatibility with your specific rifle before purchase, as some platforms have different feeding requirements.
