With a little woodworking skill, you can make the grips yourself. I've done it several times, and they came out really nice. And you can pick the wood you want if you have a Woodcraft store anywhere within driving distance of you. The last grips I made were of Bocote, and made for a buddy's old Brazilian made 32 caliber pistol.
If you were anywhere near central Texas, I'd do it for you just for the fun of doing it. I'd have to have the pistol in hand, so I can't do it long distance.
I can't do checkered grips. I might try to learn this year.
Probably somebody near you can make the grips.
