Found a 625-8 4" at the gun show today. Gun is in very nice shape. Hammer had been bobbed for some reason unknown to me. Trigger action is very smooth. Doesn't appear to have been fired much. Dealer accepted $500 OTD for it. I am a happy camper today.
You got a good deal on it and I know you will enjoy it. The bobbed hammer will be just fine unless you intend to shoot single action only. I shoot mine mostly double action only as the double action pull is real smooth and a pleasure to shoot. I have a 625-8 with a 5" barrel and really like it. Just got back from the range shooting mine and really had a enjoyable time. Welcome to the forum.
