I believe the front sight is nickel silver. It catches highlights and makes precision shooting difficult.
I got fairly good groups with it, but could do better with an all black front sight. I'm either going to have my gunsmith make a carbon steel blade and blue it, or replace the whole thing with a Ruger Ramp. The Ruger ramp is my ideal front sight, as per this one on my Colt .357:
They just look better, and provide a better sight picture, to me.
P.S. Sorry, the rod is already gone, spoken for before it got cold.
