Kel-Tec KSG410BLK: The KSG410 is the lightest thinnest and shortest 410 bullpup shotgun in the world. The KSG410 is the only dual tube .410 bore shotgun in the world. It's a design that features the dual tubes of our beloved KSG and the out-of-the-box, fiber optic sighting system of the KS7. This little beauty weighs in at only 5.4 pounds, so not only is the KSG410 slim, it's incredibly light. Like her big brothers, the KSG and KS7, this gal is 26.1 inches long, keeping all that excessive paperwork at bay. KSG410 is virtually "recoilless" by any pump-action shotgun standards we could find but we will let you be the judge of that. This extremely lightweight, slim, and easily manipulated KSG option is a pleasure to shoot for the whole family.
