Glock Question

Dan E, in the "olden days" of electroplating, copper was used as an intermediate step between the substrate (base metal) and the finish plate, usually Chromium. It is called a Copper Strike Bath and is still used in special situations. More normally, Nickel is the underlying metal beneath Chromium. That is where the "copper plated" idea comes from. And like you said, Glock rails are certainly not plated. Although your are incorrect about Chromium, it is used in plating many, many things including parts of firearms up to large bore artillery.

You are correct. Kind of. The Chromium plating in rifle barrels is a hard chrome plating that is more wear resistant than traditional chrome plating. I'm not too sure that it would be an appropriate plating fininsh on high-friction components like frame rails.

Regardless, the point still remains that Glock rails are not plated with anything. What the OP is seeing is probably wear and friction/heat coloring from the Tenefer coating on the slide wearing off on teh frame rails. That would be my guess. And probably left over factory lube.
