USP .45

The Heckler &amp; Koch USP .45 Tactical ("Universale Selbstlade Pistole" or "Universal Self-Loading Pistol") is the .45 ACP version of the USP Tactical, one of the variants of the USP. The USP .45 is based on Heckler &amp; Koch's earlier Mark 23 developed for United States Special Operations Command. It was originally chambered only for .40 S&amp;W and 9x19mm, with the .45 model seen in game a later production. The USP is used by several military and law enforcement agencies.

In game
In single player, it is the only pistol fitted with a suppressor. The unsuppressed version appears in F.N.G., Crew Expendable, and Charlie Don't Surf. The suppressed version appears in All Ghillied Up, One Shot, One Kill, Ultimatum, All In, No Fighting In The War Room, and Mile High Club.

In multiplayer, the USP .45 is frequently used because of its range and fairly large magazine. It has 4 more rounds than the M1911 as well as slightly greater range, but it has slightly greater recoil. Due to its range, it is the second most powerful pistol behind the Desert Eagle. Its one major flaw, however, is its hip fire accuracy being much lower than the other pistols while moving. While stationary however, the USP has similar accuracy to the M9 and 1911.

The model has a LAM of what seems to be the AN/PEQ-6 LAM, the LAM is purely cosmetic and cannot be used.

Call Of Duty: Modern Warfare 2
In Modern Warfare 2, the USP. 45 is held different than in Call Of Duty 4, the player has a pistol and a knife out so that when he is in CQC he can use his knife much faster.
