RESULT TIME: No damage! I did tests on the carpet and the tile floor, both places I dropped it at waist high so it hit the ground at an angle on the tip. Nothing. I held it straight out at eye level (approx. 5 feet) and again dropped it so it hit the barrel and nothing. If the ground is rough I am sure it could scratch it up, and I am sure there is a way for it to break, so I do not guarantee this, but the material is quite durable.
Interesting thing today. I pulled #4 from the mold, but this time I added some powder to the mix. Also I took the pic before I did any trimming so you can see it at it's raw beginning. All of the scrap on the seam and trigger area is wafer thin and easily rubs off with your hand.
Not a bad result, I would still paint it in this shade, but with that as a base color, it will hide scratches pretty well if you banged it around a lot. Maybe even just treating that area with a good weathering might be all that is needed. I could also try a slightly stiffer material that is clear so the color would be closer to the original. Since the stuff I am currently using is dark brown, it is mixing with the powder and darkening it up just a bit, so the clear stuff would probably be spot on, but it will be less durable. Something to consider. Either way, the powder is never perfectly uniform so each mold could have a unique swirl within the metallic color, but if it did, and you painted it, you would never see it, so no big deal.
