Silent Hill (1999)
Smith & Wesson Sigma
At the beginning of the game, protagonist Harry Mason receives a Smith & Wesson Sigma semi-automatic pistol from police officer Cybil Bennett in the Café 5 to 2. The handgun has a magazine capacity of fifteen rounds and is an overall very effective weapon. Anachronistic, as Silent Hill is set in 1983. One must also wonder why a small town cop is carrying two full sized pistols.
Towards the middle of the game, a sawed-off double barreled shotgun can be found in the Otherworld Midwich Elementary School. The double-barrel shotgun somehow holds 6 rounds before reloading, has a wide blast radius and is extremely powerful. Ammo is very scarce however and should be saved mostly for bosses and tougher enemies.
Winchester Model 70
Towards the latter half of the game, a Winchester Model 70 bolt-action rifle can be found leaning against the wall of a dirt pit near the Silent Hill Town Center. The gun is called "Hunting Rifle" in the game and it has a magazine capacity of six rounds. The gun is extremely powerful but ammunition is the most scarce and should be used only for bosses, tougher enemies, or if absolutely necessary.
One of the other main characters, Dr. Michael Kaufmann, appears to carry a Ruger Blackhawk as his primary self-defense weapon. He can be seen firing it in various cutscenes.
A bonus weapon unlocked after getting the UFO ending. The gun is powerful, has an infrared scope and unlimited ammunition.
