I purchased this revolver due to its light weight and ease of carry. I also like the power of a .357 but quickly found the DA trigger very stiff, 15 lbs plus. So I ordered wolf springs believing they would be as easy to install as in my Rugers. Removing the grip and putting a pin in the spring retainer, i see no easy way to remove the hammer spring, so I heard about someone who had used a drummel and small grinding wheel to decrease pull weight. Unable to remove the spring, I used a chain saw stone on a drill to carefully pair down the spring, moving it in several different ways. It is not the cleanest solution but seems to have greatly smoothed out the trigger without influencing the SA pull. Just be careful not to sever the spring or over grind it in any one area which may cause breakage I imagine.
