Mossberg 590 (New Shotgun in the series) – Newest shotgun in the gta 5 has a handle area and a part to put on your shoulder so you have better aim and grip on it. Very powerful gun.
Pump Shotgun – Pump shotgun is commonly used/seen in all of the GTA 5 games. Simple gun where you will have to continuously pump the gun and shoot it. Commonly used by cops. You can buy it in the ammo store, or get it when you are inside of a cop car.
Sawn-Off Shotgun – This weapon is commonly found in Grand Theft Auto: San Andreas, The Lost and Damned, and not GTA 5. It’s a double barreled shotgun that sort of looks like a gun you would see a pirate using. This gun can be bought at the ammo store for around 900 dollars.
Assault Shotgun – Is very rare. Only seen in other RockStar games like The Lost and Damned. It has two handles for the gun. One in the front and one in the back by the trigger. It’s black and sort of looks like a Tommy-Machine gun. Very high damage.
