Metal Gear Solid 2 weapons

M9
An American military M9 pistol modified to fire tranquilizer darts instead of lethal ammunition. The gun has to be cocked after each shot, since the slide locks. It comes equipped with a suppressor and a laser sight. It is moved around during the Plant chapter. Where it is found depends on what difficulty the game is on.

USP
A 9mm caliber. Developed around the same time as the SOCOM (and often thought of as a compact version of it)(the SOCOM is a .45 caliber), the USP (Universal Service Pistol) was designed to be a simpler, easier to maintain pistol for military and law enforcement forces. Used by and obtained from Olga Gurlukovich in the Tanker Chapter. It is equipped with a flashlight that Snake can use to dazzle opponents in the hold. In substance a suppressor can be found for it if you have already beaten the Tanker Chapter at least once. The USP is only used by Solid Snake in MGS2.

SOCOM
A .45 caliber automatic pistol fitted with a laser-sight, an optional supressor can be attached to it to silence it's gunshots. It is given to Raiden by Iroquois Pliskin in Strut B.Note that the bullet speed is slightly lower than the USP,especially when suppressed.Aim slightly ahead of your targets to make your shots count.It is also slightly more powerful than the USP,but not by much.

PMM Makarov
A 9mm caliber pistol. Used by Sergei Gurlockovich.

Glock 18C
A machine pistol used by Fatman in his fight against Raiden.

AKS-74u
An assault rifle used by Gurlukovich mercenaries on the Discovery and Shell 1 Core. It can be equipped with a suppressor. Raiden aquires one as it completes his disguise as a Gurlukovich mercenary. The AKS-74u is a little faster then the M4 but does lower damage.

M4
An assault rifle used by the Marines on the Discovery and Navy SEALS on the Big Shell. The version used by the SEALS has a grenade launcher attachment. Although when Raiden uses the M4 it doesn't have a grenade launcher. The M4 is a little slower then the AKS-74u, but does more damage.

 * again on the oil fence to battle Vamp after he takes Emma hostage.
