Bronze dust?

[RonDeer10mm]

Has anyone seen bronze dust on the inside part of the slide on their glocks?

It's grease with copper in it?

It's a specific type of anti-seize, used to assist in breaking the gun in. Looks coppery-

Or it could be real brass dust from cases rubbing somewhere.(mag lips, feed ramp etc) I wouldn't worry about it too much.

It is a bronze anti seize lube that Glock has used since the beginning. It is very good stuff.

From your question it is obvious that you are new to Glock pistols and the very best piece of advice anyone can give to a new Glock owner is to read the manual before you start fiddling with the pistol.
