Return the assembly back into the gun keeping the top circle in the same position as before.
Same type gun, Ruger Bisley Blackhawk ... this is easier said than done. What is not mentioned here is the slotted square that the tip of the spring assembly goes into. I've got the spring compressed with a thick piece of paper clip, and I've inserted the north end with the circle into the slot on the hammer according to the diagram. I can insert the south end into the slotted square, but I can't slide the square over the bumps on the grip frame to get it to lock into place.
HELP! I've already chingered up the slotted square, but its nothing the grips won't cover up. I also managed to poke a screw driver into the web of my left hand, which really smarts. I am doing something wrong, no doubt about it. Somebody help me.
