Well first off, 1 22 can is a good start. I have 6 22LR cans. But that's mostly due to having 6 shooters in the family. I had to get every one a can or it was a battle royal.
I run SS Sparrow, Griffin CMII, SWR Spectre, SF Ryder, TBAC 22L-1, and i have a old Sparrow.
I also have a new SAS Tolerance in route as well. It i'll be #7, And is a great 22 Can, Info on it;
The TOLERANCE is our entry into the user serviceable suppressor market. Small, light wight, extremely quiet and now able to be cleaned by the user. Perfect for all the .22 handguns on the market as well as the longtime favorite 10/22.
