Now don't get all excited, this is not a factory convertible. I had this cylinder reamed by Cylinder and Slide and then Alan Harton did the fluting and forward bevel. Gun performs flawlessly and is a whole lot of fun, especially when folks aren't expecting magnum noise and flash out of a little Bearcat. $650 shipped FFL to FFL. (Pulling due to world situation, as I don't want to have deals in the works right now)
