I was cleaning/polishing, when I realized I had 4 pistols sitting next to me while watching Tomb Raider. (none of which was a USP HK) Check 'em out, including the P3AT barrel polish, the pot metal color was heinous. Hers: Polished her barrel and feed ramp, since I had it out. Feeds Gold Dots a lot better. On an odd note, Gold Dots and Golden Saber both take a crazy shine when you polish them.
