USP .45

The Heckler & 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 the Mark 23 handgun in service with USSOCOM personnel. The 9mm version is in use with the German Army as the P8.

Call of Duty 4: Modern Warfare
In single player, it is the only pistol available 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 high magazine capacity. It has 5 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 .45 has similar accuracy to the M1911.

Call of Duty: Modern Warfare 2
The USP .45 largely retains its low hipfire accuracy while maintaining longer range than the M9. With the removal of the M1911 from multiplayer, the contrast of better aiming down the sights and better hipfire for pistols is even greater in Modern Warfare 2. It is actually a fairly useful Multiplayer weapon, as it has low recoil so you can fire many accurate shots. It is especially useful with the FMJ attachment and/or Stopping Power. In Single Player, the USP .45 can only be found with the Tactical Knife attachment, in both suppressed and unsuppressed versions. In the Multiplayer the USP .45 has the same damage stats as the M9. This is incorrect because the M9 fires a 9mm round which has less stopping power compared to the .45 caliber round fired by the USP .45. However, the enemy is just as dead if you shoot them three times with a .45 as if you shot them three times with a 9mm.

Weapon Attachments:

 * FMJ
 * Silencer
 * Akimbo
 * Tactical Knife
 * Extended Mags

Call of Duty: Modern Warfare: Mobilized
The USP .45 appears as a default sidearm in most missions in the American campaign and is only found unsuppressed. It is the exact same as the console version, but it holds 15 rounds opposed to 12. It seems to have no recoil at all though.

Trivia

 * The USP .45 in Call of Duty 4 has an AN/PEQ-6 LAM, which is purely cosmetic and cannot be used. The LAM itself was designed for the Mk. 23 and was compatible with that model only. In Call of Duty: Modern Warfare 2 and Call of Duty: Modern Warfare: Mobilized, the LAM is swapped out from the Mk 23 model to H&K Universal Tactical Light II, which is compatible with the USP.


 * With Akimbo attached to this weapon, melee will always look as if you are stabbing someone, even against walls and teammates. Also the melee is faster than normal with Akimbo.


 * The USP .45 in Modern Warfare 2 resembles a USP Compact rather than the .45 ACP Model the game depicts it as. This is common with weapons in the game such as the TMP (Resembles an MP9 more).


 * The in-game USP always fires from decocked hammer. In reality it would fire only once this way and after the first shot the hammer would be cocked by the slide movement. Next rounds would be fired from actually cocked gun.


 * The USP on the multiplayer title-screen is equipped a pistol lanyard; this makes the weapon more difficult for hostile personnel to grab and use, and facilitates weapon retention. Models used in-game do not feature a pistol lanyard.


 * The USP .45's iron sights are incorrect when using the Tactical Knife attatchment
