Looking to get my first can but overwhelmed by the amount of info out there. I have not decided on which caliber yet, but looking at either 9mm, 22 or 223. Is there a suppressor that would accommodate all three or 2 out of the three? Besides for the ability to clean at home what else should I be looking out for? I would like to do this for under 500, if possible, plus the cost of the stamp. It would be mainly used for plinking outdoors.
