Pistol

The Pistol is a gun that contains 12 bullets in 1 magazine, but it has infinite ammo. This weapon is capable of executing if you're able to land a headshot, (a critical hit) causing the person's head to explode into bits. If the person who got headshotted is a zombie, they will stay alive, but their overhead GUI disappears, which makes it rather difficult to tell how much health the person has.
