Hi Digital Shooter:
If I were your paid strategy consultant, I would suggest that your competencies seem to be in 1) creating suitable molds; and 2) customizing the materials to customer requirements.
My suggestion is stay away from direct head on competition with established makers. Offer what they don't. Such as your carbon fiber, glass fiber, etc. Good move. But think of other materials where you can leverage your mold making/fitting skills. Some want highly customized fancy grips and will pay for them. Others want simple knurled soft rubber--which seems to be difficult to find. So don't think about what you can't do, but think about what you can do if the market asks.
And to that, I think you have a niche market for custom fit soft rubber grips for high volume milsurp pistols--pa63, p64, cz82, tokarov, etc. I often see posts asking for them, but never see them sold. I think you already did the hard part--fabricate the mold. Now just experiment with rubber and I think you will be surprised at the quality you can produce and the amount you could sell...
Good luck!
