...those grips look like they'll make that load spin the gun right out of your hand to 'dink' ya on the forehead!
I’ve never been fond of Bisley grips. Better the 454 Casull because you can shoot 45 Colt cartridges if the recoil bothers you
This hand cannon should come with an NFL helmet with a full face guard to help prevent a close encounter with Mr. Roscoe........
460 S & W can shoot 454 Casull and 45 Long Colt in addition to the 460 cartridge.
I was thinking that these are birds head grips. Or did you mean that they started out as Bisley and were 'customized'.
