KSG
Kel-Tec’s KSG pump action shotgun is interesting to say the least. This shotgun was designed by George Kellgren of the Kel-Tec company.
This shotgun comes with two separate two magazines that a user can switch between by manipulating a lever on the gun. This allowed for the small pump action to have a greater magazine capacity than most other shotguns(14+1). Kel-Tec later made a larger version of the KSG called the KSG25 which could hold 24+1.
