I hope someone can help me on this,
I have a S&W model 686 and when I close the cylinder it hangs up on the forward part of the frame. Holding it back slightly it closes ok. I removed the little screw that holds the crane and cylinder in place It has a pointed tip that is receeding into the barrel of the screw which allows the crane and cylinder to move forward a little bit. The screw is so small and sharply tapered I can't get a hold on it. A schematic shows a tiny spring inside the barrel of the screw which I assume is there to keep the tip from receeding.
Any ideas?
