Cross Armory Crg+5Meg17Gd Mag Ext Glock 17/22/31 Gen 1-5 5Rd Gold Alumn
The Cross Armory magazine extension for Glock 17, 22, and 31 is a straightforward way to add five extra rounds to your standard capacity mag. Built from aluminum in a distinctive gold finish, this extension works across all Glock generations from Gen 1 through Gen 5, making it a reliable choice whether you're running a duty gun, competition rig, or range blaster. If you've ever felt cramped by stock mag capacity or just want a little extra firepower in your reload, this is a practical solution that doesn't require replacing your entire magazine.
Magazine extensions live in a practical middle ground—they're not fancy, but they work. This one is designed to stack five additional rounds on top of what you've already loaded, giving you more shots between reloads without the bulk or cost of buying entirely new magazines. The aluminum construction keeps weight down while the gold anodize resists corrosion and gives it a clean, professional look on the range or in the field.
Cross Armory has built their reputation on no-nonsense Glock parts that do the job. This extension is typical of that approach: compatible across the full Glock 17/22/31 lineup regardless of generation, and designed to withstand regular use in competition, training, or defensive carry scenarios.
