I really love short barrel carbines, and have a couple 3 SBRs. But I've stayed away from suppressors for the same reason; they take a short, handy carbine, and make it long and cumbersome.
Saw a ten inch Scorpion with an integral suppressor, which looked really cool. But that suppressor would have been dedicated to the Scorp; it seems to me, using it on numerous hosts makes more sense.
That Mirochester is about a work of art; I'm not about to hang a can on that.
