I'd like to get some true ivory for my new Commander, but I guess tru ivory might be enough. They're right up the road from me, so I ought to go check them out. If they'd install Colt medallions for me, they'd have a sale.
I have a set of Tru Ivory for my Ed Brown Kobra Carry, but I chose the slightly aged looking version. It has a yellowish tint, and the grain is more pronounced I think. I think your 70 looks great, by the way.
I like it. I plan on doing the same thing myself to my blue Series 70, but I will be going with the slightly aged/yellowed ones. Also, I would have stuck with the flat head grip screws instead of the allen head...you know...more traditional and all. But that is the great thing about the 1911. It can be personalized to the individual so easily.
