Thanks for all the suggestions. I really liked the idea for countersinking the pin holes. I was actually thinking of replacing the pins with a torx screw. ( I use mostly with knives )

The scales are very close in size to one another. I put a caliper on them to measure and both came out to just a touch over 1/8" One of them is probably about 1/64" thicker. So I'm guessing the colors are making one look larger than the other.
