If you're running a Glock 17, you know one thing for sure—your pistol is only as good as the magazine feeding it. That’s why at 3CR Tactical, we don’t mess around when it comes to Glock 17 magazines. We stock only the best, whether you’re after a Glock 17 Gen 5 magazine, an extended Glock 17 magazine, or an upgrade like a Glock 17 magazine extension. We’ve got you covered with top-tier brands like Glock, Magpul Industries, and Promag. And the cherry on top? Free shipping on all orders. No surprises, no extra fees—just solid gear delivered straight to you.
A Glock 17 magazine should do one job exceptionally well—feed rounds into your pistol without fail. Whether it’s for self-defense, duty use, or a weekend at the range, our standard 17-round Glock 17 magazines are built for the task. Featuring reinforced polymer construction, steel inserts, and precision-engineered feed lips, these Glock magazines don’t just work; they work well. If you’re running a Glock 17 Gen 5 magazine, you’ll appreciate the subtle enhancements like cutout baseplates that make reloads just a little smoother.

Sometimes, 17 rounds just isn’t enough. That’s where extended Glock 17 magazines come in. We carry high-capacity options—19, 24, 31, and even 33 rounds—so you can spend less time reloading and more time sending rounds downrange. Whether you’re training, competing, or just want the extra peace of mind that comes with more ammo at the ready, these Glock magazines deliver. And despite the extra length, they feed just as reliably as standard mags—because what’s the point of extra rounds if they jam when you need them?
If you’re running the latest generation of the Glock 17, you need magazines designed for Gen 5. Our Glock 17 Gen 5 magazine selection features Glock’s newest design improvements, including reversible magazine release compatibility, smoother follower action, and better baseplate ergonomics. The result? A more intuitive, user-friendly magazine that keeps up with the latest Glock engineering. If you want peak performance out of your pistol, start with the right magazine.
For those who believe “more is more,” Glock 17 drum magazines are where it’s at. Holding anywhere from 50 to 100 rounds, these Glock magazines let you shoot longer with fewer reloads, making them perfect for high-volume range sessions or just good old-fashioned fun. Let’s be honest—if you’ve never run a drum mag before, you’re missing out. They might not be the most practical for everyday carry, but for extended shooting sessions, they’re unbeatable. Plus, they make an excellent conversation piece at the range. Who doesn’t want to be the guy with a 50-round drum mag?

Not ready to swap out your mags but still want extra rounds? A Glock 17 magazine extension is a perfect middle ground. Adding anywhere from +2 to +6 rounds, these extensions give you extra capacity without the bulk of an extended mag. Even better? They improve grip and handling, especially for those with larger hands. We stock extensions from Glock, Magpul, and Promag, so whether you need a tactical upgrade or just want a few more rounds before reloading, there’s an option for you.
Magpul doesn’t just make AR accessories—they make Glock 17 magazines too, and they’re some of the best polymer mags on the market. With their impact-resistant construction, aggressive grip texturing, and high-tensile springs, these Glock magazines perform flawlessly while being lightweight and cost-effective. If you’re looking for a tough, budget-friendly alternative to OEM magazines, Magpul’s PMAG Glock 17 magazines are an easy recommendation. No frills, just solid performance.
If you want a high-capacity Glock 17 magazine without breaking the bank, Promag has solid options. Their extended mags—ranging from 31-round stick mags to 50-round drum magazines—deliver respectable performance at a fraction of the cost of OEM Glock magazines. Are they the absolute best? No. But if you’re stocking up for range days or need a few spares on hand, Promag mags are an affordable way to boost your ammo count.
