Double Barrel Shotgun

The Double Barrel Shotgun is a shotgun first introduced in Grand Theft Auto: Chinatown Wars and then later added to Grand Theft Auto Online as part of the Lowriders: Custom Classics update.

Grand Theft Auto: Chinatown Wars
It fires 2 powerful rounds which can take out a target from close range with extreme ease. Being a double barrel, the accuracy is somewhat better than the rest of the Shotguns. This shotgun does not seem to be based on any real life shotgun, so it's assumed that it's a customized/modified shotgun.
