For your consideration, the Kel-Tec KSG pump action shotgun chambered in 12 gauge. The KSG (Kel-Tec Shotgun) is the first entry into the shotgun marked by Kel-Tec. The size, shape, and design is similar to the currently available Kel-Tec RFB rifle, but the KSG ejects downward, instead of forward. The KSG weighs roughly 7 lbs. and is as compact as legally possible with a 26.1 overall length and an 18.5 cylinder bore barrel. This shotgun is compact, but it makes up for that with two tubes that can hold up to 7 shells each
