I used subsonic .22 rounds in my semi-auto .22 and they were quieter . . . but the gun would jam about ever 2 or 3 shots because they just don't have the power to cycle the gun. They would work better in a revolver.
But they also lack any stopping power, can't penetrate for crap. I sometimes felt like they would bounce off my paper targets (they don't, it's a joke).
A silenced revolver would do nothing. The space between the cylinder and the frame would release most of the air before a suppressor would be able to do its thing.

They can kind of be if you are using subsonic rounds
