Fancy wood for pistol grips can often be bought from gun stock makers, and blank suppliers.
Most of the blank suppliers sell very fancy wood blocks for pistols.
Finding laminated woods is TOUGH.
Most of the suppliers sell knife handle blocks and scales, both of which are too small for most pistol grips.
The companies that actually manufacture the woods, sell only in sheet quantities, and the sheets are usually WAY to big and WAAAAAAYYYY to expensive for hobby work.
One source I've used before is Texas Knifemaker's Supply:

They sell blocks up to 5"x12"x1 1/2" thick.
The laminated woods are sold under a variety of names like, Dymondwood, Pakka wood, wood micarta, Tiger stripe Resin wood, etc.
It's much easier to find fancy woods in the small quantities, and in the sizes you need for pistol grips.
