I don't SEE anything wrong, but I'm terrified that my new baby is worse for ware or the alignment/tuning is poorer or some part is bent slightly more than it used to be after being like that for so long (probably at least a week). Because S&W didn't give me any info on what they did with it the second time, I'm worried that I might just be behaving like a hypochondriac or a new parent, but I don't know enough about revolver movements and fit and finish to know if I should be concerned about something I can't see or not.
If it came back from Smith, I can almost assure you that it works perfectly....
Now...about your comments....Do not EVER watch a Smith and Wesson armorer work on your gun. Some of the favorite tools are wooden wedges and a babbit bar. A babbit bar is, literally, a round chunk of lead used to beat a Smith & Wesson revolver into submission. Files, stones, hammers and reamers are the other tools used. Its kind of like sausage...you will enjoy it more is you don't actually watch it being made.
