I won't use any J Frame grip that extends below the bottom of the grip frame. The J Frame is all about concealment and I find oversized grips unacceptable. I also dislike finger grooves on ANY grip since they are all wrong, forcing one to grip the revolver way too low. Wood grips on a J Frame tend to be much too slick and are difficult to control with any real service grade load that produces any kind of recoil. This leaves me with the Uncle Mike's rubber boot grip. Although it has that single finger grip protrusion it's still the perfect compromise.
