Umarex CO₂ Magazine for GLOCK 17 Gen.4 (KWC)

Umarex CO₂ Magazine for GLOCK 17 Gen.4 (KWC)

Because a Glock with one mag is just optimism.

This is the official Umarex CO₂ magazine built specifically for the KWC-powered GLOCK 17 Gen.4 gas blowback airsoft pistol. Not “close enough.” Not “might fit.” This one is right.

It holds 17 rounds, just like the real thing, and runs on 12g CO₂, delivering consistent pressure for reliable cycling and proper blowback. When your primary mag runs dry (and it will), this is what keeps training going instead of stopping for a refill break.

Built for realistic reload drills, duty-style training, and serious airsoft use—not for guessing games with compatibility charts.

Friendly Warning (Because It Matters)

✔ Fits KWC-made Umarex GLOCK 17 CO₂ pistols
❌ Does NOT fit VFC GLOCK magazines

If your pistol takes VFC mags, this one will not magically change its mind.

If you’re running a GLOCK 17 Gen.4 CO₂ airsoft pistol, this magazine isn’t optional—it’s essential.

Because reloading mid-session is fine.
Reloading mid-fun is not.
