I was wondering what I would have to do to my Beretta Cx4 Storm in order to be able to attach a silencer to it. It is in 9mm. Would I just have to take it to a gunsmith and have the barrel threaded? Its a chromed barrel, so I don't know if threading it would mess anything up. I know the process and legal stuff about buying silencers, so you don't have to explain any of that to me. Should I just buy another barrel and just have that one modified so I can switch them depending on if I'll be using the silencer or not? Your opinions.
