Years ago I came across a Blackhawk convertible 10mm and 38/40. I could not get over the polish and bluing that Ruger put on that revolver, it looked very high end. I think it was a special for Buckeye Sports. I wasn't looking for a 10mm but being a single action revolver, a rimless case is a nonissue. The big bonus was taking it to the range. Very nice to shoot and very accurate. I became an even bigger fan of 10mms owning this one. Glad I found it and it is a keeper.
