Jack Huntington is another to consider. He makes truly custom grips for your hand and your grip frame (he requires the grip frame and a tracing of your hand). He has done all manner of grips for many of my revolvers.
Lone Star Custom Grips. Zane is a member here & does it right. LSCG is his handle, and he's been SUPER kind in helping my Autism Charity matches AND my NRA events. He gets my vote quickly. CaryC used to do grips,,, but hasn't been taking any new orders for a while.
