I am not sure about the front sight but at first look I was thinking after market. The grips look to me to be after market. They are great revolvers for sure. I have the GP100 and love it.I thought the Hi-Viz front sight and adjustable rear sight was standard on the basic 4" offering of the newer SP-101? The polish job is relatively easy to do if wanted, and after market grips are available. I have no experience with the current offerings as I'm still tickled with my 1993 version.
