Before you go off the deep end on suppressors, figure out what you want and may want to suppress. Make a plan for what suppressors you will need so you don't invest time/money in ones that you will regret later. In particular, if you may want to swap between guns, decide on a mounting system which you can use across guns and suppressors.
I started with a Griffin Bushwacker 460 universal suppressor and standardized on Griffin's taper mount system. I've got around a dozen rifle set up with them now. I added a Silencerco Chimera as my workhorse 30cal suppressor. I've now got a Lahar-30K in the works and a SilencerCo Omega9k for 9mm pistol and 300BLK.
I highly recommend cans with "HUB" compatible, industry standard back ends, which gives you more options as to mounting.
