Well, a suppressed 22 is a silent as the grave. And you need one for a home defence pistol, and they are really nice on AR's and precision rifles, etc. I have a 45 can that covers all my pistols, but a smaller 9mm can would be nice. I have a 308 can with quick detach that covers my general purpose rifles (incl 300blk) and a direct thread for my precision 308. Plus the 22, which covers my 22 pistol and rifles.
