Just spent over 1/2 at my LGS looking at new manufacture 4" 629s. Had given up trying to find a pre-lock in my area for under 1-large. They only had four, but every one of them had the barrel canted slightly to the left (the ribs were noticeably out of line with the rear sight. The salesman acknowledged this as well. Am I being too picky? Maybe I just need to be more patient.
