Can someone post pictures of these types of issues you would look for on a new revolver?

I'm not really a revolver person but own several hand guns and rifles (SA XDM, G27, M&P 22, M&P 15T ect).

My dad ordered a 627 4" Pro Series a couple months back and would like to inspect it at the lGS before accepting it (once it comes in) but we don't really know what to look for.

Any advise or pics?
