I just bought a 5" M625-6 in .45ACP that has a 'bead blasted' SS finish. I've heard that these guns are very accurate, and am wondering about the finish. Is it durable? I'm hoping that it will not scratch or mar easily, as it looks like it could. Any of you guys have any experience with this piece that you would like to share? I get my permit to purchase tomorrow and can pick up the gun then..thanks Ron
