Nice stuff, KC911! Your Model 27 is actually sporting the S&W factory version of their "Roper" grips. You'll notice they are pretty much the same profile as the Herrett version. I prefer smooth grips, especially for guns with some recoil. I have one M29 that still wears the S&W grips, and it feels like I'm shooting a cheese grater. You'll never drop it, though...
I'm told that grip style on your Diamondback is now worth darn near as much as the rest of the gun. A lot of guys apparently took them off and lost them. My brother, fortunately, saved his. The gun had a set of rubber Pachmeyers on it when I got it from him, which simply had to go. I really don't like rubber grips on my revolvers.
Here's my M29 with the Ropers, rendered in Goncalo Alves, a Brazilian hardwood:
