Glock's, 'Gold-Colored Grease'
Ready? It's, most likely, Loctite, 'Fel-Pro' which is now known as, 'C5-A'. All of the copper-based anti-seize compounds are, pretty much the same; and, especially in a Glock, perform an identical function.
Top Glock used to sell, 'Fel-Pro' as the original, 'Glock Copper Grease'; but, depending upon what was available at the time of manufacture your, 'gold-colored grease' could be any one of several different copper, 'anti-seize' compounds.

From Glock World -
I've read that Glock, GmbH/Inc. uses this copper-based anti-seize compound as a deterrent to the slide's reset cam rusting against the tab on top of the connector, as well as to polish out any incipient roughness, or rust that might occur between the flange on the connector, and the, 'bird's head' on the end of the trigger bar. (This, 'gold grease' might, also, be something of an expedient, '25 cent trigger job' too.)
Not bad ideas when you stop to think that Glock pistols can sit in warehouses and on distributors' shelves for a year, or more, before being sold; AND, as everybody should be aware, ANY brand new polymer frame pistol can be, 'cranky', and needs to be broken in (or, 'verified').
Personally, I've never left the copper anti-seize compound on any new Glock I've purchased; but, then again, I'm a wizard with a Dremel Tool; and, the first thing I do to a new Glock is to rev up the old Dremel Tool, and go to work. (NOT an activity I would recommend to just anyone - OK!) After thoroughly polishing the action, I give the whole pistol a good cleaning, lubricate it well, and, then, begin to, 'shoot it in'.
Compared to using a Dremel Tool to do the famous, '25 Cent Polish Job', unless a Glock is going to be stored for an extended period-of-time and under uncertain conditions of temperature and humidity, anti-seize compound simply isn't needed. In my experience, 'ASC' does either very little, or absolutely nothing to improve the performance of the Glock.
