I've found the Hogue's to be far too thin in the backstrap for reasonable recoil control. They just don't fill the palm well at all. Pachmayr's are better, but personally I like a nice thick set of smooth wood grips for taming that beast. I'll second the suggestion for Lett grips. I had some on a GP100 and it turned it into a pussycat. The trick with a SA is to let it roll in the palm, and this is easier to do with smooth wood or laminate grips. If you fight the recoil, you'll just end up losing. Just go with the flow. Loose grip, but not too loose is the best.
