This is probably boring...but! Traded for a Gen4 G19, seemed like a good trade since it was NIB and never fired. Bought some Federal Champion and Winchester NATO and took her out shooting. The first outing was great, functioned like a real champ and I was happy. Then after about three or four times out it slowly started hitting me in the face with more and more brass. (I detail stripped and cleaned, so I'm sure it wasn't powder build up.) Then after a while it started stove-piping and I got a casing stuck on the rim of my glasses and it burned the crap outta me. Even by my tough buy standards it hurt for several days. So I decided to do something about it. Polished and lightly sanded and stood upside down in the dark with a blind fold on but nothing seemed to help my BRAND NEW G19 WORK RIGHT..........??? So I decided to polish the small rounded area of the extractor the fits into the recessed hole in the slide......and it works better, no brass to the face with Federal Champion after 20 rounds but I'm still not trusting her. I bought an older 90 Degree Non-LCI extractor and Spring loaded bearing to put in and see if that helps, should be here tomorrow (yes, I know my Glock is a 15 Degree, but sad to say....it's still getting traded in the next time I'm at the gun shop.) I called Glock once, they told me to pay for shipping and send it to them. Called Glock again and they said they would pay for shipping, but only after I asked..? Still, I decided I do not want them to keep my brand new pistol for 3-8 weeks and send it back to me saying "Meets Specs" or something generic like that. Sorry, just needed to vent a little. I'm done now. Okay, now I'm done.
