My Friend currently lives overseas and he own a Colt Python Revolver, and a Colt Diamondback Revolver. He wants me to buy him original (OEM) Main springs for each of the guns. that is the simple part. the hard part is that he also wants me to buy him special trigger springs that lighten the trigger pull. He says these springs makes the trigger so sensitive that a feather can pull it. Does anyone here know where to buy these spare parts.
