What were the 9 different cans you ran and how many rounds did you put through each before making your decision?
I did not record what they were, and to me, it really made no difference. We had a "sales rep" with over 2 dozen different types and sizes of suppressors at our shooting range, and he allowed us to shoot any and all suppressors. I picked the "biggest" suppressors he had, shot 5 rounds through each one that I had picked out, and went with the one that was the "quietest" and had the least amount of felt recoil. Nothing fancy and nothing really scientific about it, but I was satisfied and that's all that counted!
