Of course, that got me thinking, how I'd really prefer an aperture sight anyway... 
However, when I grew up, a 'hermit' of sorts lived next door, and taught me that with a little patience, you could make most anything out of a scrap of metal and a file and drill (...in fact, he'd done some time in jail for doing just that...). Anyway, I found an unusually thick 3/8" or so washer just a bit thicker than the sight blade's groove, drilled a smaller hole through one side of the washer, cut off the sides, cut off the base, file the lower part with a step-off so it rides on the rear sight base, and viola. . .
The screws on the sides of the base are for adjusting the windage (once I get it where I want it, I'll either swap out for shorter set-screws, or file the sight narrower where the set-screws hit it, so they wind up flush). The front sight adjusts for elevation using a screw above the muzzle (where a Redhawk's sight-swap button is).
I really like the sight picture - once I blue the sight, it should work perfectly for my needs.
