OK, so Ive got my new to me Glock 23 that I did a little frame sanding on. I tend to have a really high hold on the grip so naturally I suffer from the "Glock Knuckle" on my middle finger because of the blocky trigger guard, so I decided to carefully take a Dremel with a sanding drum to it. I now have it adjusted like I want it and was wondering if anyone knew of a good way to shine the plastic back to match or closely match the rest of the polymer factory finish. I was thinking of carefully and slowly rubbing the area with a little acetone, what do yall think. Thanks for any ideas.
