Those are beautiful grips. I think you should buy a Redhawk to put them on. They would look best on a blued one, but stainless is nice too.
Some time ago, I had a stainless 5.5" Redhawk .357. I bought it sort of on a whim, for a good price. (Actually really good, considering how the value of those guns has gone.) When someone listed a set of grips very similar to yours on the classified board here, I came this close to buying them. Another fellow beat me to them, and a year or two later, I decided to sell the gun. I loved owning it, handling it, looking at it... but found I never shot it. So I got back what I paid and bought another gun I'd long been itching for.
If I had bought those grips, I bet I'd still own the Redhawk today, and I bet it'd be one of my favorites.
You should buy one.
