The 9mm Pistol is a semi-automatic handgun and the first firearm Gordon Freeman acquires in Half-Life 2.

The 9mm Pistol is the Combine's standard sidearm and is often carried by Civil Protection officers. It is a reliable and accurate weapon with a high firing rate, a sizable 18-round magazine but relatively poor damage. It is a useful all-rounder and is particularly effective against weak or slow enemies, such as Metrocops, Headcrabs, Barnacles, Zombies and Scanners. The weapon's features include a metal grey slide and a prominent black muzzle compensator that reduces muzzle climb.

The player first acquires the 9mm Pistol at the start of the Half-Life 2 chapter Route Kanal, after defeating the Metrocops beating a Citizen in a maintenance tunnel near the City 17 Trainstation. However, it is possible to obtain the gun earlier than this near the end of the chapter A Red Letter Day by stacking up crates and killing the Metrocop on top of the trains. In Episode One, it is found in the City 17 Underground. In Episode Two, it is found early on while trekking through the Victory Mine.


The 9mm Pistol is not particularly effective against multiple targets, and is better used when facing only one or two targets at a time. The recoil makes it difficult to quickly fire the gun while retaining any accuracy past short range, so shots should be fired at a lower rate to hit enemies at medium to long range. When engaged in a firefight using the 9mm Pistol, aiming at the target's head is advised, as it normally takes only two headshots to kill. On the other hand, aiming for the body is not very effective, especially if the target is wearing body armor, and it can take up to seven shots at medium range to score a kill. Despite the lower damage, it is significantly more accurate than the Submachine Gun and does a little more damage, making it convenient as a backup weapon if the other weapons are running low on ammo. Ammunition for the pistol is plentiful in the early chapters while battling Metrocops in the Canals, but it becomes slightly harder to come by in later chapters, where it is usually only found in some supply crates and abandoned outposts.

Both Metrocops and Combine Soldiers can be killed by a single headshot if they are unaware of the player's presence, even in Hard mode. This can also be done with other weapons.[1]

The 9mm Pistol is one of only two ranged weapons that can be used underwater, the other being the crossbow.

Behind the scenes[edit]

  • The 9mm Pistol appears to be based on the real-world USP9 Match by Heckler & Koch.
  • In the playable Half-Life 2 leak, the 9mm Pistol has a larger texture and ejects spent cartridge casings.
  • The leak 9mm Pistol uses some sounds now used by the Submachine Gun; its reloading sound, and its firing sound when fired by an NPC.
  • Textures for an earlier 9mm Pistol model can be found in the playable Half-Life 2 leak files.
  • While the leak 9mm Pistol and the Submachine Gun share the same ammo shell model when firing (similar to the Pistol and Submachine Gun in Half-Life), in the final game it was removed for 9mm Pistol, while kept for the Submachine Gun.
  • The 9mm Pistol was originally to feature a burst fire mode as the secondary attack. Seemingly being a leftover from this cut feature, a bug existed where players could hold down the secondary and primary fire to "charge" their next shot (it would fire several shots at once at the same angle, essentially creating one extremely powerful shot). The bug has been fixed in the May 26, 2010 update applied to Half-Life 2 and Episode One.


  • When the 9mm Pistol is fired by the player, no spent cartridge casings are ejected, while it does when fired by an NPC. This is most likely a development oversight, while in the beta the Pistol fired by the player ejects a spent cartridge.
  • Sometimes, there is a glitch that the CPs will shoot his "Invisible" pistol, this can be seen in the chapter Route Kanal when the CPs rush to the player on the train track at long range.
