The Umarex Heckler & Koch USP air pistol uses a CO2 cartridge and fires 4.5 mm steel BBs. Its semi-automatic blowback action cocks the hammer and feeds the next BB into the barrel. The metal slide locks back when the magazine is empty and is released using the slide release lever.
The frame is made of plastic, and the smooth barrel is metal. The fixed sights have white dots, while the grip and magazine catch have an anti-slip texture. On the left side are a hammer decocking lever and a safety lock. The 22 mm Picatinny rail allows accessories to be fitted.
