bluetopper, I found a useful alternative for both my Ruger SuperBlackhawk .44 Mag and Taylor/Uberti 1873 Colt .45.
I used the "old" Testor's red model airplane enamel paint to put a drop on the tip of the 1873 front site, but today you can get blaze orange enamel at a craft store. On the Ruger, I got a bit more detailed since the back sight is not just a "v" groove. I painted the tip red, the next area left black, then a red strip, and the rest black.
That gives you 4 sight pictures if you hold the front sight at 6 o'clock on your target and just align the back sight even with all of the red and black strips at the various target distances. I shoot these guns at 15 yards, saving my Super Redhawk in .44 Mag and Casull in .454 for longer distances with red dot sights. When I could hold the Ruger still when I was younger, I shot 180-grain HPs at 200 yards at bowling pins.
