I picked up my 629-4 today to put a few holes in some paper (The paper was asking for it !) I loaded it with some 240 grn swc drew a bead and squeezed the trigger, click no roar I opened the cylinder yea I put the bullets in the gun. I drew another bead on the target squeezed the triger, nothing on closer exam the firing pin was broken off. has any one had this happen ?? the gun wasn't dropped or used as a hammer. What a bummer I'm glad I had my 686 with me I was still able to punish that evil paper.
