Two weeks ago I acquired a new Redhawk in 45 Colt with a 4 inch barrel and Hogue Bantam grips. My question is ........how do I remove the grips? The little plastic tool that is included is just about useless. I have RA and I don't have much strength in my hands at the moment. Also, is it a standard Redhawk grip frame and will standard Redhawk grips fit? I sent an email to Ruger customer service and they were no help at all!
