Well after much searching on the Web, I decided to order the Tru-Glow Illuminator sight set. I happened to be at Dick's yesterday, and they had one in stock so I bought it ($29.99). It consists of an aluminum Williams rear base, with a plastic insert (double dot). The front sight is a plastic ramp and single dot insert. The contour of the sights very closely matches that of the barrel. I decided that as they are so light in weight, that I would try to bond them on the barrel. I used a dremel tool to "roughen up" the I.D. of the sights, and also the barrel area where it will be mated to (the idea is to greatly increase the bonding surface area by creating a rough surface). I bored a small hole in the front sight so it will fit right over the bead. I squared the barrel in a vise, and located the rear sight position. I cleaned the surfaces with acetone, and then used a 2-part epoxy epoxy so secure the sights to the barrel, clamped them in place, and left it to cure overnight. Today, I am post-curing it at ~60C (here at work in an oven).
I plan on testing it out this weekend, so I will keep you posted as to how successful I am.
