I appreciate the responses. I have tried to join the Rugerforums before but cannot as they won't accept my email address ... yahoo.com ... for whatever reason. I got an answer from Ruger and they priced out sending the revolver back into them, fitting a new .45 colt cylinder, and return shipping. Not too bad considering the good deal I got buying the BH. I think I am leaning toward Ruger doing the work.
Thanks again,
