Maybe this LGC Member owned company can help. They do custom 1911 grips. Check with them for deets. Good luck!

From their etsy shop: "Welcome to my woodworking store. All items are hand made by me. The finest in custom 1911 pistol grips, reloading blocks, boxes, puzzles, toys of all types and whatever else suits my fancy.
Open for business again with limited items, but more will be on the way soon!"
