I had a local gunsmith convert a 629 for me. I found a mountain gun barrel and had him re-chamber the cylinder. I now have sort of a square butt mountain gun in 45 colt with correct throats. It shoots great.
Beautiful gun! That's the only sure fire way to get a .45 that will shoot. I had Andy Horvath do mine and like you I couldn't be happier. Time for a range report.
