USP .45

The USP .45 is a handgun featured in Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2, as well as Call of Duty: Modern Warfare: Mobilized.

Call of Duty 4: Modern Warfare
"Semi-automatic with medium capacity and power. Effective at close range."

- Sidearm description

Singleplayer
The USP .45 is a common starting sidearm and the only sidearm available with a suppressor in the campaign. The unsuppressed USP .45 appears in F.N.G., Crew Expendable, and Charlie Don't Surf. The suppressed USP .45 appears in All Ghillied Up, One Shot One Kill, Ultimatum, All In, No Fighting In The War Room, and Mile High Club. As with most sidearms, the player may choose to swap the USP out with a more powerful weapon.

Multiplayer
The USP .45 is frequently used in multiplayer because of its range, high magazine capacity and early unlock level. It has five more rounds than the multiplayer M1911, as well as greater range and slightly greater recoil. Due to its range, it is the second most powerful pistol behind the Desert Eagle. Its major flaw, however, is its mediocre hip fire accuracy compared to that of other pistols while moving.

Weapon Attachments

 * Silencer

Single Player
In Single Player, the USP .45 is always found with the Tactical Knife attachment, although the game never identifies it in the weapon pickup text. The only true variation of the USP .45 found in singleplayer is with the suppressor attached to it. In campaign, no matter where a USP .45 is obtained, it will always have 72 rounds with it. While breaching a door, any USP .45 the player has in their inventory will gain full ammunition (as well as the full magazine) with a maximum of 120 rounds.

Multiplayer
The USP .45 largely retains its low hip fire accuracy and recoil while maintaining longer range than the M9. FMJ does not work well with the USP .45 due to its low starting penetration and semi-automatic firing. However, other attachments are just as useful as they would be on other weapons. Also, due to a glitch with the M9, the USP .45 is the only weapon in the handgun class to support a fully functional silencer.

In Hardcore, with Stopping Power, the USP .45 can be a one-hit-kill sidearm at any distance. While in close to medium range, the USP .45 will still maintain a one-shot kill, even without Stopping Power.

 * Extended Magazines

Singleplayer
The USP appears in Call of Duty: Modern Warfare: Mobilized as one of the two sidearms available in-game; the other being the M9. Unlike on the consoles, the USP has a 15 round magazine, as opposed to 12 rounds. It's recoil also settles much faster, resulting in more accurate shots. In singleplayer it is also incapable of a one-shot kill at close range if not headshot, but can kill in 2-3 shots at any range. Aside from this the USP is mostly the same as the console versions. However, the weapon's benefits are short-lived, since the USP is only available in one singleplayer level, "Needle in a Haystack".

Multiplayer
In multiplayer, the USP is the default sidearm for the Coalition faction, it is the same as the M9, but due to clearer iron sight and less usage in campaign is much more used than the M9. However, the iron sights are misaligned, as the real point of impact lands on top of the right dot, and its power is decreased, taking 3-4 shots to kill, depending on range. On top of this, the USP has terrible hipfire accuracy when moving, being almost as inaccurate as an LMG from the hip; but when stationary, it has much better hipfire accuracy (perfect when crouching).

Trivia
USP .45
 * The USP .45 is one of the few weapons (along with the M9 and the P90) to match its maximum ammunition in both Single Player and Multiplayer. Most weapons have either much lower or in rare cases much higher maximum ammunition in multiplayer (the remaining handguns, oddly, have higher maximum ammunition).
 * In Call of Duty: Modern Warfare 2, on the left side of the gun there is a text that reads, "USP .45ACP" in white-gray text. It is clearly visible if the pistol is on the floor.
 * When Akimbo is used, the slash knifing animation is replaced with that of the stab. However, this has no actual effect on the function of the knife.
 * Also when Akimbo is used, the player can see the left gun is just a mirror image of the right gun.
 * In all games featuring the USP, it shows the gun with its front iron sight slanted to the left.
 * In Modern Warfare, in all SAS missions, the USP .45 will always be silenced, with the exception of Crew Expendable and F.N.G.
 * Call of Duty: Modern Warfare: Mobilized is the only Call of Duty to have its HUD icon for the USP .45 show the barrel extension.
 * In Modern Warfare 2, Akimbo is the only attachment where it shows the slide locking back once the player has no ammo left. However, there is no sprint animation for the weapon with its slide locked.
 * As with all handguns when the player sprints with the USP .45, they will hold the gun with two hands in first-person while in third-person the player only holds it with one hand.
 * In Modern Warfare 2, the USP .45 is the only handgun with a functional silencer.
 * In Modern Warfare 2's Museum, the USP .45 Silenced is stronger than its unsuppressed version.
 * In Modern Warfare 2 Single player, the unsilenced USP's iron sights have the zoom of a Red Dot Sight while ADS whilst the silenced USP's iron sights have no zoom while ADS.
 * In Modern Warfare the USP shares its firing sound with the M1911.
