The grip frame is similar to a Colt SAA, Ruger Blackhawk, or Ruger Vaquero.
Shooting large caliber high power handguns takes a special technique and practice. You have to learn to work with the recoil, not against it. The single action grips allow the gun to roll through your hand under recoil. If you work with it, it really works well. Now, admittedly, my buddy at the gun shop calls me the worlds foremost leading recoil junkie.
