Riot Shotgun

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

Characteristics
The riot shotgun is a semi-automatic shotgun with a drum magazine. It has high damage-per-second, due in part to its large ammunition capacity when compared to other shotguns and its high rate of fire. With the Shotgun Surgeon and And Stay Back perks, it can be a very devastating weapon in close quarters combat. It also reloads much faster than any other shotgun and therefore can change ammunition type very quickly. But, like most shotguns, it suffers at mid to long range due to its poor weapons spread.

Locations

 * Camp McCarran - fiends near McCarran may drop them (in poor condition).
 * Gomorrah - the Omerta thug guarding the bank has one. This is generally the only way a low-level character can get one, as he always has one even at level 1.
 * Gun Runners - can be bought from Vendortron after level 16.
 * Hidden Valley Bunker - Torres sometimes sells them, in varying states of repair.
 * The Tops - the Chairman guarding the bank has one.
 * Vault 34 - located in the armory.
 * It is also possible to find one during a quest for the Van Graffs, at the final confrontation between the Van Graffs and Caesar's Legion where three of the Legionnaires carry riot shotguns (if above level 14).
 * Some NCR Veteran Rangers carry riot shotguns at higher levels.
 * At the Second Battle of Hoover Dam, if you've recruited the Great Khans, they will show up carrying riot shotguns.
 * NCR troopers sometimes carry them at the Second Battle of Hoover Dam in the power plant if you are helping the NCR.
 * White Legs occasionally drop them at high levels.
 * Marked men regularly carry them at high levels.
