For more than a decade titanium nitride has been a popular protective hard coating for internal gun parts such as gas pistons, firing, pins and AR bolt carriers that requires only minimal lubrication. But now a company near San Diego is offering a full gun coating service. (Thanks to Terry H. for the tip.)

JWR’s Comment: I wistfully remember shopping at the San Francisco Gun Exchange right in the city’s financial district, back in the early 1980s. The store was always crowded with well-dressed business executives during the lunch hour. The store had very politically incorrect door handles fashioned from elephant tusks. The store’s inventory was varied, the prices were fairly competitive, and there were a few jaw-dropping “display only” pieces. The Gun Exchange was owned by a very friendly Jewish couple named Posner. It had started out as modest pawn shop in the early 1960s, but by the 1980s it catered to high end gun collectors. It was sad to see how the hoplophobes made one whole sector of righteous commerce impossible for an entire city. Don’t let the gun grabbers run amok in your town, folks!
