I bought the Presentation model grips for my Ruger Redhawk .45ACP/.45 Colt revolver. The fit is perfect. I don't typically care for finger grooves, and like the classic S&W type grip. The only thing I will say is that when you tighten down the single screw that goes through and holds the grips on, you get a slight bulge on the left side where the screw pushes through. You can back it off and not make it so tight, but I chose to grind about 1/16" off the end of the threads and polish it up, and it no longer causes the bulge.
