Can someone explain to me what the big deal is (besides the "ohh it looks badass machine gun like) with the popularity of the micro carbine, 3-4 inch barrel sub guns that hold 20-30 rounds. It a pistol. It's not really easily concealed, other smaller handguns have high caps approaching 20+ rounds (XDM 19, Beretta 18, Glock 33 rounds). I'm reading reviews about what great guns they are for home defense, great backpack guns, blah blah blah. But other than the cool factor, why? I guess I'm just not getting it. This is Frasier Crane, I'm listening . . .
