Anywho, after shooting today I asked her about cleaning and she said she hadn't in a while. I told her I would clean it. The last time I saw a gun that dirty was about $15 years ago when my buddy and I blew 250+ Chinese surplus rounds in an afternoon through my SKS. The surplus ammo is some nasty, dirty stuff. It's also "mildly" corrosive. It took me a couple dozen of patches to get the barrel, chrome lined mind you, clean.
This Glock 19 was that bad. The barrel alone took about 20 patches. The frame took 15 more. The slide was another 20. The slides first 6 patches were completely black from powder and gunk. It was nasty. The moral of this story...clean your gun !! And the 2nd moral...damn Glocks are reliable.
