Just thought I'd provide some feedback on the Wollf spring kit and the Ruger SP101 .357 trigger. I picked up a new SP101 .357 3" snubbie this year, and I really like the gun. This is a solid, heirloom-quality gun. The trigger out of the box was decent, but it was certainly stiff. I can report that after having my Smith replace the trigger and hammer springs with the Wollf kit, the trigger is really, really good. Others have reported that the SP101 lends itself well to a bit of trigger work, and they are quite right. I put 100 rounds through the gun to test it, and not a single light strike. I would recommend this approach to any SP101 owner.
