I have a SilencerCo SS Sparrow. In my quest to have a variety of host pistols, I have pretty much all the autoloaders threaded now that make me happy. I have a blued 4.5" Ruger Single Six that I think would be fun to silence. I have read many comments that because of the barrel/cylinder gap, that trying to silence a revolver is a waste of time. My observation has been that when shooting a silenced autoloader, that just as much flame, and blast comes out of the ejection port, as comes out of the B/C gap of an unsilenced revolver. There doesnt seem to be much noise from the ejection port on the silenced autoloader. Why would the B/C gap of a revolver be any different?
