I had a Model 28 N frame that came with the tiny factor panel grips. I bought a Hogue rubber monogrip with finger grooves and loved it. I later aquired a round butt 686 that came with wooden grips made by Ahrens which were fingergrooved and round to square conversion type. I figured they would be great since they looked like the Hogues. Not so. Apparently the coke bottle shape from the rear view, which is called "palm swell" by Hogue, is somewhat unique to them and these Ahrens grips don't have it. I must really like palm swell. I bought a rubber set of Hogue rubber monogrips for the 686--round butt conversion without finger grooves and love them, except how they look. But I pause at putting up $125 for Hogue fancy hardwood. Does anyone know if that palm swell characteristic can be found elsewhere? Or if one can sand/file down grips to have the feature without damaging them?
