Quick Q: does anyone know how the front sight on the adjustable sight Browning HPs is attached? Is it dovetailed, or pinned or brazed? Some of the early catalog pix show a dovetailed sight (I think), but later pix don't seem to show any dovetail. I'm wondering about swapping adjustable sights on one of these for fixed and wonder how hard it may be to find a used one with a dovetailed front sight.
