The one that started it all. The KSG was Kel-Tec's first entry into the 12 gauge shotgun market, so naturally they had to completely redefine it by setting a new standard in both magazine capacity and overall length. Here's the short and not-so-long of it: Legal in all 50 states, the KSG holds 6+6+1 (or 7+7+1 depending on shell length) in a 26.1 inches package. That's not a typo- it holds a lot of ammo at just over two feet long. It comes standard with an 18.5 inches barrel and Picatinny-style rails for mounting your favorite accessories on both the top and bottom.
