Finally got around to shooting my new gen 6 and noticed my brass all have a weird circumferential ring about 3/16th of an inch back from the case neck. They are also slightly bulged aft of this ring compared to forward of it.

Is this normal for the new gen 6 or do I have a messed up chamber?

It's their new stepped chamber in a new barrel 100% normal.

A whole new meaning to "glock bulge"

Is the brass reloadable?

Germans use a stepped chamber for 9MM and yes its reloadable. Wlther did it in the original PPS. Originating from Georg Luger's original patents, where the chamber features a slight reduction in diameter near the mouth to improve gas sealing

Interesting, I had no idea that the G6 used a stepped chamber.  My PPQ has it as well.  It seems to be the cleanest shooting pistol that I own and the most accurate 9mm I have ever owned.  I can shoot hundreds of rounds through and it never gets as dirty any my other guns.

Not to thread slide, but...

Does this mean the Gen 6 guns will be
better for shooting suppressed?
i.e. not only cleaner, but less gassy
if shooting braced?

Thanks!

Thread slide away… Asked and answered thanks guys! It isn’t typical for Glocks to have QC issues so that’s what I figured, just didn’t remember anyone mentioning it in the reviews.
