As I mentioned in my video of the Umarex P99 Clear Plastic Spring Airsoft Pistol, I can be a bit of an Airgun snob and I tend to stay away from the clear Airsoft guns since I like mostly metal guns with blowback operation. That said there is a place for these clear Airsoft pistols. The Umarex HK USP Clear CO2 Airsoft Gun other than being clear looks like a gun and shoots like a gun but will not be confused as being a real gun which can offer some more safety and less stress to all parties involved.
