From understanding booster systems and blowback management to choosing the right caliber, there's a lot to consider before your first suppressed range day. This guide breaks it all down, covering everything from Nielsen devices and fixed-barrel setups to the best pistol suppressors on the market and why 9mm and .45 ACP reign supreme for suppressed shooting.
