A 9mm pistol can will suppress subsonics, but cannot handle any other rifle rounds. A .45 pistol can will handle .300 blackout subsonic and be useful any centerfire pistol cal below .45. Any time you buy versatilty you get a sweet spot for a given setup, and less performance anytime you shoot a smaller diameter or higher pressure round through it. My source for this info was my SOT, and you should consult with someone you trust before dropping your coin on a given setup.
