If I were to purchase my first suppressor, which caliber/weapon system should I get first? The three options I would consider would be a 9mm handgun, a rifle in 5.56, or a rifle in .308. I'm thinking the .308 because it is the loudest of the bunch. But the 5.56 probably gets shot the most. Not 100% sure why I would consider a can for a 9mm handgun other than the "cool factor".

Thoughts?

Thanks.
