1911 pearl grips

This may be cliche. After the passing of Robert Duvall, rip gus. I noticed he had a pearl handled 1911 with air cav on the grips in apocalypse now. I wasn’t in the army but I have a nice full size 1911 that would be a good tribute to him. Anybody have any ideas on where I could find some? I found some for the officer but not commander
