Georgia gun store in Gainesville had one in the other day. Not sure if it's still there though..... I actually thought it was kind of neat, if I wasn't saving my scratch for something else I'd have probably got it.
He KSG is gimmicky....loading is difficult, manipulating he crossbar barrel, selector is clunky and awkward.
The UTS-15 fixes those two issues and basically ensures reliable feeding for all intents and purposes from a single 14 round magazine. That's awesome firepower....provided they function and you never get any grit in the mags through the witnessing holes in the mags. And like soviet said its balance is...dinked.
The 930 SPX is a proven auto design, kiss simple, and very reliable. For me and my kit, I pick it every time.
