First, I'm kinda wanting a suppressor. It would be used on a G19 and G17, so obviously 9mm. What's a good "first" one? I'd like the shortest (length) one possible. What's is a fair price? Second, is there much sense in making an SBS, like a 14" one? I have an 18" 870P. I don't know how much of an advatage I'd have for HD/zombies, by cutting 4" off.
