I put a Wilson Combat trigger spring kit in my 642 today. It made a huge difference in the trigger pull. I used the 14# trigger spring and the 8# hammer spring. Took all of 15 minutes to install. However it seems a little harder to stage the gun, and the final "single" action pull is a little gritty. Is this normal? Do the components need to break back in now that the springs are different? I rechecked my work and the gun functions fine. I put a couple cylinders though it and it shoots fine as well. It has really helped my DA accuracy with the gun.
I put the Wolff spring set in my 442 (10# main and 8# return) and it turned it into a buttery smooth easy shooter. Accuracy improved tremendously. Mine is very smooth all the way through. I ran many hundreds of rounds through mine both before and after the switch and I didn't have any break-in time necessary. It was buttery smooth from the minute I changed them out.
I changed out my Ruger SP101 main spring and it seems to have a little of the characteristics you have described. Not bad, but noticeable. I'm going to smooth the edges of the shaft the main spring rides on and then polish it with a dremel and metal polish to see if that smooths it out. You might try that with your 642 and see if it helps.
