Heather Mason, the player character, picks up the Handgun the floor of a clothing shop in the Central Square mall is a 92FS Centurion semi-automatic pistol. It has a ten round magazine capacity, wood grips, and the ability to mount a sound suppressor looted from a corpse entombed in a concrete pillar. Douglas Cartland, a private investigator hired to find Heather, uses a similar weapon, but never fires it onscreen in the game. The handgun is the only firearm in the game that the player must obtain.
Colt SAA
Used only by a few monstrous Nurses in Brookhaven Hospital, this revolver is used rather inexpertly (but nonetheless lethally) by those monsters, and cannot be obtained by the player. The Nurses can only fire it slowly at Heather, but never need to reload. Contrary to its name, the Bulletproof vest item will not actually stop rounds fired from this weapon at Heather. If Heather closes to melee range with a revolver-wielding Nurse, the Nurse will try to pistol-whip Heather instead.
Remington Model 870
The Shotgun is in an opened gift-wrapped box in the subway level. Heather can commandeer this grisly "gift" and blast monsters away with its buckshot. It has a sawn-off barrel (the front sight is entirely missing), a tube magazine capacity of six rounds, and, for some reason, is completely reloaded by inserting a single shell into the magazine.
MAC-10 Dressed Up As Uzi
The first fully-automatic weapon ever implemented in a Silent Hill game. The Submachine Gun can be found in the basement of Brookhaven Hospital near a bloodied wheelchair, the barrel still warm from its recent use. It has a 32 round magazine capacity and can use the sound suppressor as well, which would imply that it shares a caliber with the handgun since suppressors are manufactured for specific calibers to be effective. An unlockable version with unlimited ammunition is available as a bonus item.
Though not terribly effective for most enemy encounters anyway, the decision to include a fully-automatic weapon was still criticized by some game reviewers as placing too much emphasis on firepower within a survival horror game, and to date this game remains the only Team SilentSilent Hill title to give the player control of a fully-automatic weapon; however, Silent Hill 4: The Room has an unlockable MAC-11 submachine gun as a weapon for a friendly NPC.
Flamethrower
Essentially a submachine gun that projects a stream of flame. It has unlimited ammunition.
