First time I have had a issue with an Glock
I have a G17 RTF2 that I purchased new several months ago.
For reference I have owned several Glock 9mm pistols and never had any issues what so ever.
This G17 RTF2 I have has 600 to 700 rounds through it I always use Winchester white box 115 gr FMJ factory ammo which i have used in all my 9mm Glocks for the past ten years.
This pistol has two issues.
1. Every 20 to 30 rounds I am getting a stove pipe malfunction, I have never had this before so I am sure it isn't technique or ammo causing this issue.
2. This issue is kind of unusual. What I am seeing is a carbon/ burned pattern on all my brass coming out of this pistol.
The carbon/burned pattern is consistent and always in the same place on the brass. This pattern goes from the mouth of the brass 80% down towards the head of the brass and it encompasses about 25% of the circumference of the brass. This issues indicates a possible out of round chamber or something of that nature.
Does anybody have any ideas ?
I will be calling Glock this week but I would like to get some feedback from you guys first.
Has the pistol always given the burn pattern on the brass, or is this something that just started with the jams? It does sound like something is off with the chamber to me. Do you have another G17 barrel you could drop in to see if that helps?
I wonder if the stovepipe malfunction is somehow related to the weak ejection (brass to the face/erratic ejection) others are having in pistols from this timeframe. I'd try to get the new ejector installed in it first and see if that fixes it.
Change ammo. WWB has become the worst. For the longest time, I never had any problems with it. Lately, there have been a number of issues. Accuracy, weak loads and malfunctions have become a part of it.
YMMV

I am going to agree with this. With Olin moving their ammunition manufacturing out of East Alton there have been rumors of the ammo quality going down hill. Supposedly it is due to the workers at the East Alton plant expressing their displeasure at the move to a non union plant.
My nieces husband was laid off from the East Alton plant recently.
I could agree with the lack of quality of the ammo.
But I have several boxes that are at least three years old and maybe older.
So I don't think i can attribute my issues to the ammo.
Mim xtractor and 336 ejector....
Replace with current spec parts.

You may be right about the stove pipe jams, and OP you should check the number on your RSA as well, glock has changed them a few times, make sure you have the latest one installed. But how would that cause the caron/burn pattern on the side of his cases.
Cases being sooty doesn't matter. I see them sooty all the time. It is ammo dependent.
Some will say it is bc the gun is extracting early while the case is still pressurized...true but it doesn't matter if the extractor and ejector do their job.
Shoot suppressed and you get it all the time...doesn't impair function.

Fair enough. Perhaps like you say there is an issue with the gun unlocking early, causing the jams?
No, it's the extractor first and then the ejector. If those work, it doesn't matter bout the rest.
Burning on the outside of the spent casings suggests that the slide is unlocking early. Try replacing your guide rod assembly / recoil spring.
The failures to eject may be caused by weak ammo, or residue built up around the extractor. A detail strip cleaning of the slide and its internal parts may fix the problem. If you use oil on the slide's internal areas or internal parts, wipe them absolutely dry before reassembly.
