Measuring in at only 16.5+ inches, the Serbu Super-Shorty shotgun is quite possibly the shortest 12-gauge pump action shotgun in existence. CNC-machined in house to military specifications by Serbu, the Super-Shorty is based on your choice of a Mossberg 500 or a Remington 870 and holds a pair of 2.75 inch or 3 inch shells in the magazine, and an additional round in the chamber. Perfect for storing under your car seat, by your bed, or concealed inside your coat pocket. Available now at Serbu. – $1,050.
