Alright guys, my stamp for my suppressor should be arriving next month sometime (6 month mark) so I want to buy a new 9mm for it. I think I've narrowed it down to the following: Glock 19 S&W M&P - Pro maybe FNP/X/S - haven't decided which model CZ P07 Duty First, is there a threaded barrel available for all the guns I have listed?? I know the Glock for sure has one, what about the others? I need a little help deciding. I love Glocks, I have 2 (22 and 30) so I kinda want something else. But, what do you guys recommend? Also, feel free to suggest others I have not yet mentioned. Thanks.
