This gas blowback airsoft pistol by KWA has fully licensed H&K trademarks. If you're looking for a realistic USP with great performance, this gun is for you. KWA has gone out of their way to make this gun as realistic as possible. Not only does the gun have fully licensed H&K trademarks, it also has many other features that you would find on the real H&K USP. The gun is, of course, fully made of metal. Like the real thing, it has a double action trigger and a functional, decocking safety. The magazine release on this pistol is ambidextrous as well. Unlike the lower end gas pistols, you must rack the slide before you can fire this airsoft gun. The realism of this gun is phenomenal and makes it a great training tool. The KWA USP also has the NS2 gas system which makes it more efficient and gives it better performance on the field. The Tactical version features a FDE (Flat Dark Earth) lower frame, raised iron sights, and a 14mm ccw threaded outer barrel.
