I am in need of a main spring for the above revolver. I had to remove the hammer and trigger to correct for push off using the stones. However, on the last assembly of the main spring, I broke the one end of the cup that attaches to the hammer strut. I tried all the known venders and goggle with no luck. If any one has a spare or a known source, I will appreciate letting me know. If not, I guess I will have to make one. thanks in advance.
