P-T does that work as well. Depending on the type of front blade you have. If the blade is pinned in the make a replacement blade, in black, so it just drops in and you get a black blade in case you have a stainless pistol. My ramps were integral to the sight rib. They machined the ramp off, bead blasted the sight plain, and dovetailed in a black sight of the correct height. I prefer a green dot on front since it is the brightest most visible coler to the human eye, but P-T will do orange.
