On Youtube, Larry Potterfield of Midway USA has a series of videos on S&W revolver "stuff'. The link is only one of a series, and he does have a video of the sight replacement process, front and rear for S&W. Might have to search a bit. They tend to be plugs for his wares, but they are well made, clear, good sound and easy to understand.
