Sight Upgrade for D Frame Colts?

Just beginning to research whether or not the front sight on a shrouded D frame can be upgraded beyond painting the factory ramp.

Your thoughts?

A sufficiently motivated ($$$) gunsmith could no doubt mill down that long shallow ramp and dovetail in anything that suited you.

Jim Watson, above, is correct. I had a Colt Magnum Carry with the same profile and had the front sight milled down and a dovetailed patridge with gold bead put on. The new sight picked up quite a bit faster in various lighting conditions. Jim Stroh did the work and even offered the option of what size gold bead to use.
