I have decided that I would like to get my first suppressor. The gun I will be setting up for it is a stock SP01. Obviously, I have to start with getting a threaded barrel. Can someone with some suppressor experience give me some advice on what I need to do internally to change and optimize the setup for shooting subsonic ammo suppressed, i.e., any and all swapping of springs, recoil, hammer, trigger, and anything else I should know. New to this world, not new to CZ's, big fan. Thanks in advance for anyone that can give me some solid advice...
