After 10 years and somewhere between 30k and 40k rounds I believe I have worn out my 610. It was a pawn shop purchase so don't know history before me but I know I have put it through the ringer. Was shooting local match and partway through stage 4 of 6 the hammer stopped coming back ...cylinder spins and locks up tight ....went to safe area and did not see anything obviously broken (NO PARTS FELL OUT) reassembled and still would not work ...two days later picked it up and it worked like nothing was wrong ..took it to range and ran about 80 rounds through it before could duplicate issue ....trip to my local smith is in its future
and before suggestions are made ...already tried to talk to wife into a 8 shot but she's not buying it.
