The Cross Armory magazine extension for Glock 17/22/31 is a straightforward way to add capacity to your standard Gen 1–5 frames without swapping the entire magazine. Built from gold aluminum, this extension sits flush at the base of your mag, giving you those extra rounds without the bulk or complexity of a full-size magazine swap. Whether you're running drills at the range, training for duty, or just want the flexibility of a few more rounds in your carry setup, this is the kind of practical accessory that doesn't get in the way.

Cross Armory keeps the design simple and reliable—aluminum construction resists corrosion and won't add unnecessary weight, and the gold finish holds up to regular handling. The extension works across all Gen 1 through Gen 5 Glock 17, 22, and 31 frames, so if you've got one of those platforms, you don't need to worry about compatibility surprises. It's the kind of mod that shoots smoothly into your routine without fuss.

If you run multiple Glocks in that family or just want to squeeze a bit more capacity out of your favorite mag, this is worth keeping on hand. It's not flashy, but neither are you.
