I had a 1861 Navy Revolver. It chain fired on me. Only two cylinders thank goodness. But it shook the front sight off the thing, scared the devil out of me, and stretched the frame. I took it to a very good gun smith. He shortened the frame and replaced the pin and when he was done, he said it was as good as new. Well it no longer wiggled around as it did after the accident. But I never had the nerve to shoot it again. I sold it "as a wall hanger" to a person and told them what had happened to it. I have no idea if they ever shot it after that.

What make is the revolver? Perhaps they have a customer service that could check the thing out. The other thing you could try is to tire shoot it. Load it, put it in a tire and with a long string fire off each cylinder. Then check to see if it is damaged more. But I personally would find a good gun smith and have them check it. It if is something likes a stretched pin, they can replace that and get it working fine again.

Otherwise, clean it up. Make it look pretty, and hang it on a wall.
