Material spec - custom automag grips

[musashi]

Hello all,
I'm looking to confirm a material spec on the stock plastic grips that were available on the aluminum WGP cast triggerframes and/or the automag composite injectionmolded/cast trigger frame. These are the grips that have one attachment screw per side.

I'm guessing that it's an injection molded abs resin (or is it polypropylene?) with a mild UV stabilizer... anyone have an SAE spec? I can't find my micrometer so i don't know what the "skin" thickness is. I was also wondering if there were any issues with the material "sinking" in the areas where the stiffening ribs are molded.

Thanks for your time.

Dern, I brought it here so Tom would see it quicker. If anyone knows the answer to this, Tom will.
