Not rust, a sort of copper grease. All glocks ship with a dab.

my g23 has the same, thought to be grease from factory

Arrr...these be gold flakes, my friend. Nothing to worry about. Seriously...you're good to go.

I actually bought a tube of that grease it's called antiseizing copper grease C5-A from Loctite. I used it when I was building my err nvm...

Ha! Me too. Some are concerned about it.....others buy it. Go figs'.

This is a glock 19. Not even fired yet, only dry fired. Is there possibly already rust? (have had for just a few weeks)

NO, it is a dry lube Glock puts in the firearm. Don't try to scrub it out.

My reasoning is if it works for Glock it "should" work on my nvm.

That is factory lube. You might run a few hundred rounds before cleaning it and using whatever lube you prefer.

If it wipes off with a q-tip you are good.

I bought some too, thinking it would help break in other polymer wonders. Maybe a noticeable difference, nothing definitive.

You can shoot it like it is or clean and lube. Either way will be fine.
