What Caribou said. Hammer spur is different as well. Before you buy, try to handle each one to see which feel you prefer. If possible, shoot each one. Some say the Bisley handles recoil better. The traditional grip rolls upwards in the hand when the revolver is fired. Some like it, some don't. I think the Bisley grip frame is better if you have large hands...traditional grip is small and some say they have to curl their little finger under the grip to be comfortable.
