How to install a narrow piece of glass into it, could be hard. Any solution?

I don't know. Back in my millwright days, when I worked on coal pulverizers/boilers, there was an 'eye' for looking into the coal furnace...I think it was made of 'Mica'...Something hard like that would work, if it could be glued in...

Ah! Lexan (or Makrolon) is the trademarked-name for polycarbonate. My metal supplier has 12" sheets of it for ~$2.00/sheet. I'll get a sheet with my next order.

The spec sheet says high impact resistance but low scratch resistance. That sounds like the opposite of what a pistol grip should have...

Almost...you'd want high impact resistance and high scratch resistance. Unfortunately, you won't find much in the plastic realm that satisfies the latter. If G.T. is sending you clear mica, I think it will be authentic and effective. Known in the old days as isinglass, should perform well in all respects if it's ultra-clear grade. Impervious to glues of all formats, cuts with scissors or matte knife. I think inorganic is the way to go.

Polycarbonate is available with one side hard to resist scratches--albeit only longer than most other plastics. It is tougher than you can even imagine. Tested some 2" wide strips X 1/4" Polycarbonate in the 80s, with sledge hammer blows. It would distort plenty, and definitely was mooshed around by the hammer face, but it never cracked, no matter what. I used panels of it to enclose a mechanical sculpture that was installed in a public space.

Just for the sake of argument, why would you want high impact resistance? The grip is going to break if hit hard enough...Why have the window remain intact?

No, he has something else. Not Mica. He thinks maybe plexiglas...

I'll give it a try. I'll order plexiglas too. It's cheap.
