About the Umarex H&K USP CO2 GBB Pistol

Umarex now offers the H&K USP series in a CO2 Metal Gas Blowback version. This is for players who prefer all of the benefits of CO2 powered airsoft pistols such as, harder more realistic recoil, better cold weather performance for year round play and ease of use and simplicity in regards to trying to find Green Gas in your area. Green Gas is a HazMat item and is very expensive to ship and order online. This pistol uses standard 12 gram (12g) Metal unthreaded Co2 cartridges which are available almost anywhere. This pistol has a metal slide and textured polymer frame like the real thing. It’s fire controls mimic that of HK’s USP Variant 1. The magazines are metal as well and hold 18 rounds of ammo. This is a different gun and internal system compared to the previously available USP Gas blowbacks which used Green Gas and were made with Umarex and KWA. Be sure to stock up on the extra correct Co2 Magazine for this gun.

Q: Will my Green Gas magazines work in this airsoft gun?
A: No, only the co2 magazine designed for your gun.

Q: Will they offer green gas magazines for this gun?
A: No, the internals are completely redesigned to handle the extra pressure from the Co2 cartridges and wouldn’t function properly on green gas even if you could some how make a green gas magazine work. If you like green gas pistols, please Click This Link To See The Green Gas HK USP Pistol.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
