Looks like a fun project, I would of sent it back to S&W for a full rebuild. I would also change out the grips, sights and springs before shooting. Did you shoot it before dropping it off for coating? I would hate to see it coated and then have a problem that need serious work. Please post pics when you get it back and good luck, I love my 1006 & 1076, built like a tank. $300 was a no brainer....
