Here is a photo of my DC 3" .327 SP101 with the Altamont Snake Skin grips on it. They are the same dimension as the factory boot grip with wood or plastic insert, but are much more attractive to me on the revolver.
Below it is the 2 1/8" .357 SP101 with the newer Pachmayr Diamond Pro grips made for the revolver. They are a wee bit shorter than the Hogue Monogrip which is positioned behind it, but are fatter through the palm and more bulbous on the butt. (
They should be much better for larger hands)
They seem more comfortable to me with an average size 9 glove hand.
Either the Hogue or the Pachmayr are more comfortable and controllable to my hand than the factory, but neither conceal as well as the Ruger factory grip which is pictured to the right for comparison.
That is not to say that the Ruger or Altamont grips are all that uncomfortable or uncontrollable for me, they aren't. For their concealability, those are what I'll stick with.
Just had to try the others.
I do own a set of the old Eagle Boot Grips for an SP101, but they never fit quite right without shimming on the inside. For my hand they were never a more comfortable, controllable, or concealable option, but they are the smallest all wood for the revolver that I've personally seen.
