9mm Pistol (Half-Life)
|9mm Semi-Automatic Pistol|
The Pistol is among one of the first weapons received, acquired in the early stages of the games. It has both primary and secondary firing options. Its primary attack fires accurate shots at a slow rate, while the secondary attack fires quick but less accurate bullets. The latter is recommended to be used only at close range. It shares ammo with the Submachine Gun, which makes it very easy to find ammunition for it throughout the game. It is one of the few weapons that is able to fire underwater. As it is very accurate at long range, the Pistol is ideal for picking off enemies from a distance where they have a hard time counterattacking. The weapon is suited to taking out weaker enemies such as Zombies, Headcrabs, and Houndeyes.
- In Half-Life, the Pistol can first be found in the chapter Unforeseen Consequences; it can be obtained by killing the first seen security guard or dropped by a dying guard before the player exits the Anomalous Materials laboratory. In Residue Processing, it can be retrieved from a security guard being eaten by a Barnacle.
- In Opposing Force, the player finds the 9mm Pistol in the chapter We Are Pulling Out, after a tram ride.
 Behind the scenes
The Pistol appears to be based on the real-world Glock 17; with the High Definition Pack, it is based on the Beretta M9. It was originally to have an attachable suppressor. Scrapped in the final version, the attachment and detachment animations are still in the model file. It is unknown where it would be obtained. As the suppressed Pistol is used by female Black Ops assassins as their primary weapon, it is likely it was to be acquired through killing one. One of the early Half-Life demonstrations shows that the Pistol used the suppressed firing by default, had the slide to be pulled again after reloading, and had a 12 magazine capacity instead of 18.
The Pistol had 18 magazine capacity in the initial release (version 22.214.171.124) of Half-Life. It was changed to 17 in the patch 126.96.36.199, which was released on December 22, 1998. Half-Life expansions and ports also have the same magazine capacity.
There is no secondary attack in Day One.
 In other media
The Tranquilizer Gun featured in Team Fortress Classic uses the Pistol model, with the unused suppressor attached to it. Similarly, Team Fortress Classic's Sentry Guns use the unsuppressed Pistol firing sounds.
