I file a shallow groove into the rear face of the front sight and fill it with white Testors. Yeah, there's the Friendship thing, but I'm old, my range of focus is pretty non-existent, and I have a mild cataract in my shooting eye. My score will not be very threatening. I don't care what anyone says about the sight, I enjoy shooting, and they can complain or disqualify me if they want, but I'm going to make it a fun day.
