I was thinking the other day that if I had to discharge my G17 defend myself in my home that my wife and I would probably lose a significant portion of our hearing. Small price to pay for protecting myself and my family, but nonetheless undesirable. I have been considering a 9mm suppressor anyway mainly for plinking and suppressor education work. My question is: what is the legality of using a suppressor to defend oneself? I remember reading somewhere that carrying a suppressed pistol concealed is a NO-NO, but I can't remember where I read it. Is home defense any different?
