Optimal can for Beretta M9A3

[40 lines per inch]

I went back quite a ways looking for this information, but I am sure it has been discussed before here.
As a long time Beretta affectionado my latest acquisition is the M9A3 9mm and now I am shopping
around for opinions, on the optimal silencer for the m9A3.
Joined this forum particularly to research this topic, any help would be appreciated.
