I don't think so. Not anyone who actually worked at HK unless you were talking to the janitor. The USP has never been plated. Any plated jobs were done on refurbished (after market) police trade-ins and then sold off (and not by HK). You can cover a lot of blemishes with a coat of soft nickel, but HK never, ever, nickel plated any USP or USPC.
