Midway USA and Brownells both have ivory bead sights back in stock. The sights at both places are a .157" (4mm) bead with a threaded shaft. The Brownells sight lists their shaft as "undersized" and says you should use epoxy to install. The one from Midway is the NECG sight linked in JDW's post above and it has the typical 6-48 threaded shaft.
I ordered the one from Midway last night and so we'll see how it works out.
My Paragon requires a straight shaft that is press-fitted into the recess. Since the Midway sight has a larger diameter shaft, I figure I can simply sand it down to the necessary size and I'll have what I need.
Anyway, for those that were interested in finding a source for the ivory bead replacement sights, they're back in stock at these 2 retailers.
