I only own double action revolvers at this point. I would love a .22 single action, and have some questions. I found an old blued single six at a pawn shop. It is a 3 screw. The ejector housing and under side of the grip frame have some wear and appear to be made of cast iron. Is this the case? It looks like super shiny metal- not metal that would be blued. It almost looks like paint has worn off. Anyway... It has the old model sights. I think this means it is a flat top? Is 250.00 too much to pay for this revolver? I do want to shoot it, I just don't like the look of the "cheap metal." Any help would be appreciated. Thanks!
