Riot Shotgun

The riot shotgun is a weapon in Fallout: New Vegas.

Characteristics
This riot shotgun is a semi-automatic shotgun with a drum magazine. With the Shotgun Surgeon perk, this gun will make short work of anything at very close range (especially with slug rounds), also good for fighting multiple enemies. It also reloads much faster than any other shotgun and therefore can change ammo type very quickly too. The riot shotgun is the New Vegas equivalent of the combat shotgun.

Locations

 * One is located in the armory in Vault 34.
 * It is also possible to find one during a quest for the Van Graffs. At the final confrontation between the Van Graffs and Caesar Legion where three of the Legionairres carry Riot Shotguns.
 * Sold by the Gun Runners at 100% condition, just around the corner from Freeside's East Gate
 * Some NCR Veteran Rangers carry Riot Shotguns.
 * The Omerta Thug guarding the bank in the Gomorrah has one.
 * The quartermaster at the Hidden Valley bunker sometimes sells them, in varying states of repair.

Behind the Scenes
The "Riot" shotgun most probably refers to the real world automatic shotguns, created to control rioting in prisons and such.
