I have a SP101 in .357 with the shorter barrel. I have the factory grips that I'm not overly impressed with. I also have the Hogue grips that are very comfortable and make it easy to shoot the gun. I have relatively small hands but they fit the Hogue grips just fine. My only gripe is that the rubber finish on the hogue grips catch on my clothes and are abrasive to my skin I I don't wear an undershirt. Do y'all have some suggestions that would work a little better for me?
