Did mine with a Dremel tool and a sanding block. Easy. I wouldn't say it looks "factory," but it's not bad, and it cures the Glock trigger guard ugliness. The plastic where I sanded it is smooth, not grainy like the rest of the plastic. Sorry I can't post a picture--too computer-inept. I've heard of people restoring the grain with a soldering iron, but I'm not going to try that unless I can see it done first.
