This would require a bit of talent but...........I found some stuff online called mold making putty. It's like a play doh, but dries into semi hard silicone. I'm going to use some to make a custom button pannel on my gun. Anyway....one could probably use this stuff to make custom grips as well. You just need a pattern and a way to punch out the screw holes. Just a thought......I'm trying to find some in black right now.
