For sale is this umarex HK USP CO2 pistol, comes with one magazine and some extra co2 cartridges (see photos) the slide lock is the wrong size and doesn’t lock open on last round but does manually, some cosmetic cracks to the plastic body around the safety catch but this is common on these guns, does have some weight about it with a metal slide and magazine! I’ve not used this in a game been sat under my bed for over a year now! Any questions please ask
