True, glocks are an exception bc the frames are plastic so they can't serialize them easily other ways. I seen other plastic guns (like hipoints and polymer80s) do the same. There's safeguards against this though, I know there's a place you can cut on a hipoint to find a hidden serial even if they remove the plate. Smith & Wesson actually got sued to add an extra hidden serial to their guns. A bunch of plastiguns have this kind of stuff for exactly this reason.
