Layers and layers of mis-information here. Anyway you can't even work a Colt without knowing how to tweak and improve factory springs. Long before Wolf and the aftermarket parts business came on the scene S&W revolversmiths learned how to shape and tune main springs and it ain't done with heat, a wedge or screwdriver handles etc. The image shows stock factory far right, Wolf and two of my tuned K & L springs for comp guns. After 20-30K rounds they are still reliable enough to leave the strain screw setting depth as is. Enough said
