Thanks for the tip. My 460 S&W was sent back to Smith and Wesson to have a Master Revolver package done and an added "fixed" trigger over-travel stop installed. I also sent it into Cylinder and Slide to be bead-blast finished and carry beveled, along with my 500 S&W 6.5 inch half-lug barrel. They discovered the 500 S&W had too large a barrel cylinder gap (.009 or more) so they figured out a way to take the sleeve off of the outside of the barrel and set the round barrel back to accomplish a tighter, but not too tight,.005 barrel cylinder gap. I will let you know what I can when I find out. Thank you!!
