When I bought the revolver, I measure .008” B/C gap. After shooting and cleaning a few times, the gap is now .010-.011, depending on the rotation of the cylinder. S&W sent me a return label, and said they’re running about six weeks out right now. It’s not spitting, but +P loads send a good flame outward from the gap. The CS rep didn’t say that gap was within spec, as is often posted online.
Thanks for any answer!
