I have a newely made Glock 17 serial number "SSL" all Austrian pistol that came brand new in the box. Right out the box, it spewed brass everywhere (Left of the gun, dribbling out of the right side of the gun onto my right hand, and especially back towards me in my face and right shoulder). My Glock 17 really really liked kicking brass back to my face almost every shot. Nothing was consistant...matter of fact the only thing consistant was that it was never consistent. Now to all you nay sayers who say, "Stop limpwristing"-That pisses me off to no end on this forum.....I am a LEO of ten years, an expert rated shot every year on rifle and pistol. I DONT limp wrist. I also used tons of different types of ammo. I had several different officers and civilian friends of mine shoot it and they all experienced the same issues. I even tried the new ejector Glock sent me that they used in the Gen4 guns. Still no fix. SOLUTION........ I heard that Glock issued a bulletin and advised it was phasing in a new style non dipped extractor. I ordered one and instantly installed it and shot it. RESULTS........ Instantly fixed the problem. Brass in a nice little pile at the 4 o'clock position four to five feet away. Not one single piece of brass to the face. This was with the 336 ejector when firing with the newer non dipped ejector. SO.......... It seems Glock has or had a quality control problem and fixed their "out of spec" extractor with a new one. There you have it. It just sucks that I had to pay $20 for a new part that I shouldn't have had to pay for, but at least I got to shoot a lot.
