Combat shotgun

A combat shotgun is a weapon appearing in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Fallout Shelter.

Background
A combat shotgun is a shotgun that is intended for use in an offensive role, typically by a military force. While limited in range, the multiple projectiles typically used in a shotgun shell provide increased hit probability unmatched by other small arms, usually utilized in close-range combat. Most combat shotguns are fully automatic and have a drum magazine, giving them a definite advantage over break-action double-barrel shotguns.

Winchester City-Killer


A Winchester City-Killer 12 gauge combat shotgun, bullpup variant. In excellent condition, it has the optional DesertWarfare [sic] environmental sealant modification for extra reliability.

H&K CAWS


The Heckler & Koch HK CAWS (H&K CAWS) is a prototype automatic shotgun—designed as a combat shotgun—co-produced by Heckler & Koch and Winchester/Olin during the 1980s. It was Heckler & Koch's entry in to the U.S military's Close Assault Weapon System program.

Pancor Jackhammer


The Pancor Jackhammer, despite its name, is an easy to control shotgun, even when fired on full automatic. The popular bullpup design, which places the magazine behind the trigger, makes the weapon well balanced and easy to control.

Drum-magazine combat shotgun


This unnamed model has a large drum magazine, a fire selector switch located inside the trigger guard, and a protruding muzzle-brake of the barrel and is found mostly on the East Coast.

An automatic, 12 gauge military shotgun. The best weapon for close quarters, except for a flamethrower.

SPAS-12


The SPAS-12 was designed in the late 1970s by the Italian company Luigi Franchi Spa as a special purpose, military and police close combat weapon (SPAS originally stood for "Special Purpose Automatic Shotgun"; it was later renamed "Sporting Purpose Automatic Shotgun" in a failed bid to get import approval to the United States). This two-handed shotgun rapidly fires a thick, deadly blast of pellets.
