Trivia

The USP is currently the only weapon that will visually display when it is out of ammo.
The USP can kill human players, except the MTF Commander, with one shot, by landing a headshot assuming the class doesn't have a max HP greater than 100. With the Heavy Barrel attachment equipped all human classes except MTF Commander can be one tapped.
The Epsilon-11 can do the same with its Heavy Barrel attachment assuming the target has the burned effect and is not a class with more than 100 HP.
When the USP is dropped, multiple parts of the model disappear such as the trigger and magazine.
USP stands for Universelle Selbstladepistole (English: Universal Self-Loading Pistol)
