The Global Ordnance GO MAG is a solid third-party option if you're looking to add serious firepower to your Glock 17, 19, or other 9mm double-stack models. These magazines are produced in South Korea with a design that mirrors many aftermarket offerings: a hardened steel insert surrounded by a durable polymer body that's fully metal-lined to prevent deformation.
With a 33-round capacity, you're getting significantly more ammunition before needing to reload, which makes these especially popular for range sessions, competition, and pistol caliber carbines. The anti-tilt follower inside keeps rounds stacking reliably, and the overall construction feels substantial in hand. The black finish matches standard Glock aesthetics and blends in with most setups.
Keep in mind that like most high-capacity third-party mags, the springs can feel stiff when loading the final rounds, and some users report durability concerns if dropped from significant heights with a full load. These perform best as a fun, budget-friendly way to stretch your range time rather than as a primary self-defense magazine. If you're planning to use these in a PCC build or just want extra magazines for the range without the factory price tag, the GO MAG delivers straightforward functionality at an accessible price point.
Yes, this magazine is fully compatible with the Glock 19 as well as the 17, 26, 34, 45, 47, and 49. Any 9mm double-stack Glock will accept it. The extended capacity does mean it will protrude below the grip, but that's normal for all 33-round magazines.
The GO MAG uses the same basic construction style as Glock factory mags with a steel insert and polymer body. The main differences are price and some users report the springs are stiffer when fully loaded. For range use and training, it's a budget-friendly alternative, though some prefer the assurance of factory mags for mission-critical use.
Absolutely. These magazines are popular for AR-9 and other PCC platforms that use Glock-pattern magazines. They're especially useful for reducing reloads during longer range sessions or in competition environments where capacity helps.
Like most 33-round magazines, the springs are designed to keep all those rounds compressed and feeding reliably. When you're loading the final rounds, especially rounds 30-33, you'll feel resistance. This is normal and actually a sign the spring is doing its job. A magazine loader or practice helps, or you can use a speed loader.
The polymer construction is reasonably durable for normal range use and handling, but dropping a fully loaded 33-rounder from height can stress the seams and potentially crack the plastic. Treat it with care and you'll get good service out of it. For everyday carry or defensive use where durability is mission-critical, factory Glock mags are the safer choice.
That depends on your style and how long you want to shoot between reloads. A single 33-rounder gets you a lot of trigger time, but many people rotate 2-3 magazines to keep shooting while one is being loaded. For serious range sessions, having at least two gives you more convenience and lets you manage your pace better.
