Yes they had the recall, you can just google it. I don't think it is that big of a deal. S&W will pay for it, some people had it done and others didn't. If it has the letter M stamped in the crane then it was already done. Just google 586 recall and you can read all about it. If it is a good deal, i wouldn't stop me from buying it. Call S&W and give them the serial# and they will let you know for sure.
Hope this helps!
