This Global Ordnance 13-round magazine brings proven reliability to your Glock .45 at a straightforward price point. The polymer body pairs with a hardened steel insert inside, matching the construction approach of factory magazines while keeping things simple and functional.
The GO MAG comes with an anti-tilt polymer follower that keeps rounds feeding reliably and serves as a quick visual check when you're running low. Numbered witness holes on the side let you count your remaining ammunition without opening up the mag. The construction is drop-resistant and built to handle repeated loading, unloading, and range use without losing its shape.
This magazine works across Glock's .45 ACP double-stack lineup. The 13-round capacity fits the Glock 21, 21SF, 30, and 41 equally well, letting you use the same magazines across multiple pistols if you run more than one. It's worth noting that these mags will protrude slightly when loaded into subcompact models like the G30, but they function without issue.
Glock-pattern magazines from third-party makers have earned their reputation through consistent use at ranges and in training. The GO MAG follows that formula with basic, no-frills engineering. You get durable materials, reliable feeding, and a magazine that doesn't require special care or break-in time.
This magazine is designed for Glock's full-size and compact .45 ACP double-stack models, specifically the Glock 21, 21SF, 30, 30SF, and 41. The 13-round capacity is the standard for these models. While it will fit subcompact models like the G30S, it will extend beyond the grip.
Yes. The GO MAG uses a hardened steel insert and anti-tilt follower design that follows the same basic architecture as factory Glock magazines. It feeds standard .45 ACP ammunition without requiring a break-in period. Most users report reliable function right out of the box.
You can use them interchangeably across any Glock double-stack .45 platform that accepts a 13-round magazine. If you own both a G21 and a G30, for example, the same magazines work in both pistols, which cuts down on your inventory.
Both use polymer bodies with steel inserts and anti-tilt followers, so the core design is the same. The main difference is manufacturer and typically price. Aftermarket mags like the GO MAG offer the same capacity and basic reliability but at a lower cost point than OEM Glock magazines.
