Airsoft World/Airsoft Scotland has this Double Eagle  M81 USP Airsoft Electric Pistol with a shiny effect on its upper slide. Something for two-tone pistol collectors to think about... "Something a bit different for all the would-be Ganstas out there. Take a DE USP AEP, polish the slide then add tritium sight markers, and Voila! A pistol that gives you an excuse to sit in the dark 'polishing' it. Purrfect!"
