A Glock Factory Extended Magazine for Gen 5 models gives you more rounds downrange without swapping magazines. This genuine Glock mag works across six of the company's most popular 9mm handguns—the full-size Glock 17, compact 19 and 19X, subcompact 26, competition-focused 34, and the newer Glock 45. Whether you're stocking a duty rig, building a home-defense loadout, or running drills at the range, OEM Glock magazines are the reliable choice that fit like they were made for your gun—because they were.

Factory Glock mags are engineered to the same exacting standards as the pistols themselves, with robust feed lips and springs designed for thousands of rounds. They're straightforward to maintain, affordable to stockpile, and instantly recognizable on any range or in any kit. If you shoot a Gen 5 Glock in 9mm, extended-capacity factory magazines are a smart addition to your spare-magazine rotation.

One heads-up: new Glock magazines can feel stiff when you first load them—that tight spring is intentional and part of the design. The mag may resist taking all rounds until it's been cycled a few times or left loaded for a few days to allow the spring to settle. Load it with all but the final round, let it sit for a handful of days, or run it through several load-and-unload cycles to break it in. After that initial period, it'll load and feed like a champ.
