HK produced some Nickel P7M8's, P7M10's and P7M13's in in 1992 (KC date code). There was a company called RTB Imports who sold some hard chromed P7's, P7M8's and P7M13's that appeared to be factory hard chromed, but they were not. CDNN and HK parts.net sold some nickel and hard chromed police trade ins. Some people think those were factory nickel or hard chromed because of the factory looking barcode/sticker on the outside of the box, but were are not. To my knowledge, there are no true factory hard chromed P7 series pistols. I have had a few factory (kC) nickels, after market nickels and aftermarket hard chromed P7 series pistols over the years. The hard chromed ones tend to hold up much better and not flake off or scratch as bad as the nickels.
