I've held BFR revolvers and fired/owned several Ruger SA's. I recently sold my Hunter model and will probably replace it eventually, possibly with a BFR. I'm not looking at the long cylinder models, probably a straight 45 Colt or 454. Looking for BFR owner opinions on the quality/durability of their revolvers versus the Ruger. The loose cylinder lock up of Rugers has always troubled me.
