I've seen questions posted on other forums about what Glock puts on there slides at the factory for lubricant. I know it's a grease of some sort with fine particles of copper in it. I was at a local machine shop today and the guy I was talking to had a can of this stuff called "Kopr-Kote" which is an anti-seize lubricant. Looks like the same stuff Glock uses. All the Best, D.
