Sawn-off Shotgun
The Sawn-Off Shotgun is a weapon available in Grand Theft Auto: San Andreas. Despite being a Shotgun, its held like a Pistol and you can run while having it out. Sadly it only has two rounds before reloading which takes a few seconds. Like most of the single-handed weapons in San Andreas, it can be dual-wielded when you reach the Hitman level.
