Ther's always real Ivory. Nothing looks, or feels like real ivory, and it ages well.
I can't realy afford in on all my guns, but that's what I would have if I could.
I had a Colt SAA done if real Ivory last November for a friend and it was great. Guy named Paul Pershing in El Paso, TX., made and fitted the one piece grips and they were the nicest grain I've ever see on a pistol. The price was reasonable for Ivory and I was very satisfied.
It's something to think about, anyway.
