I ended up sending it to Frank Glenn. He was very fair and got my m19-3 running. Smith and Wesson said it was a gas ring problem so I sent him the yoke and cylinder and he replaced the gas ring. That didn't work so I sent him the entire gun a d I got it back today. I shot a box of. 357 158 federal jacketed soft points, then a box of .38s. No issues.
Everything seems perfect.
