When I wanted some Pachmeyers for my SBH (cut down to 4"), I thought it would be a simple find. Come to find out, my choices were limited. This was due to the fact that it was stainless not because of the model. It seems that for some reason, the SBH stainless gripsframes differ from the blued ones. :? I ended up getting a pair of Pachmeyer "gripper" style ones. (I needed them with the really hot loads)
If you prefer wood grips, Lett or Eagle should be able to fill your needs.
