I recently picked up a S&W 37 from and estate, for a good price. Upon firing the revolver, the rebound would not reset the trigger forward. Suspecting that coils were clipped on the rebound spring, I replaced the spring with a Wolf 11 pound spring , same problem. Then the spring was replaced with a 15 pound spring, same problem. I am now waiting for an factory 18 pound replacement. While waiting, I have polished the rebound slide sides and edges and the hand that turns the cylinder. The hand appeared to have drag on the slot in the frame. The revolver has been stripped one piece at a time until only the trigger assy, hand and cyl stop assmbly remained. It still has a catch, or drag which seems to still indicate excessive friction where the hand goes through the slot in the frame to the cyl. I hesitate on removing any surface from the hand until I replace the rebound spring with an 18 pound factory spring . Your recommendations will be appreciated. [the rebound spring WAS 2 coils shorter than the Wolf spring]
