I never noticed this before, but I'm getting copper shavings in the chamber/barrel.

Is it normal for a GLOCK? Could it cause a "KB" or other malfuntion if I put enough rounds through it?

I'm using Wolf and Rem GS.

no problem.  remember to thoroughly clean your firing pin channel as they get back there too.  No oil in the channel.

Is it shavings, or is it a copper colored dust/residue? I had a similar observation, and was told that it is part of the lube from the factory. I don't know for sure. I noticed mine in the slide area

new glocks come from the factory with a copper colored lube on the slide.

+1 its true. More to the point though the areas where the frame and slide meet.

Thanks, noted.

Shavings.
The factory grease is almost completely absent from the slide now.

Clean you barrel and don't shoot that dirty woof crap. I find wolf hg ammo to be some of the worst stuff out there. Whenever I shoot it I notice it sparking out of my barrel.

Glocks eat wolf like candy.  I have never had 1 malfunction with wolf ammunition other than the very occasional dud primer, which only makes for good Tap, Rack practice.  I have on more than one occasion witnessed glocks (my own included)  fire several thousand rounds without cleaning and no deterioration in performance.  When it came time to clean, i cleaned the gun in the sink with palmolive and a toothbrush and everything came right off.

If you're gun doesn't shoot wolf, it's your guns problem.  Wolf is quality ammo and the only stuff i use for practice and training.
