The OP said he bought a Super Red Hawk.
Evergreen, sounds like you have a regular Redhawk. Big difference. The Super Red Hawks have the same grip pegs as the GP100's, and the Hogue Grips with the Sorbothane fit the Super Red Hawk. Just checked the Ruger site, and it looks as though the Super Redhawk (non-Alaskan) comes with the regular Hogue Grips (not the tamer variety with the sorbothane). I have the Ruger Super Redhawk Alaskan.....and these came with the Hogue Tamer Grips. I guess I assumed incorrectly that all Super Redhawks would come stock with them.
The Redhawks (non Super) have a different grip peg, and the only Hogue grips I have seen do have an exposed backstrap, and are not so comfortable.
