I find it's usually ammunition that causes any issues in Glocks. Very rarely is it the fault of the firearm itself...

 

If I were the OP, I would just send it back to Glock. Get them to give you a shipping label... or in my case, use an FFL to ship it to them via USPS (much cheaper than FedEx/UPS) and have Glock give you 2-3 free magazines for your trouble.

 

Usually with most guns it's a couple common reasons - ammo, cleaning/oiling or lack there of, and limp-wristing or one-handed shooting.

 

I can tell you that it wasn't any of those reasons, or at least from what we think.

 

Maybe I will have him post a picture of it. It was a VERY odd FTE as well, I have never seen one like that one before. The casing was parallel to the barrel and made it's way all the way up to the top of the ejection port.

This actually happened last night with a Glock 19.

 

It actually happened with several brand new duty weapons

I got the new spring in today.. I brought the old one with me and shot 100 with both..old springs 2 malfunctiona new spring non... Old spring 4 in grouping.... Which is awesome for me at 10 yards.. new spring all over the place... I'm sure its me though cuz when I was dead on I was stacking. Old spring much stiffer compared to the new. New spring doesn't eject brass half way across the range like the old one did, gunna put a grip spacer on it next time with just the new spring and hope making it almost the same size as my 21sf will help

Good. Dont use the old spring then. The accuracy might be because the new spring is causing a different type of recoil impulse that you are not use to. The spring never touches the barrel when the slide is on the frame and has nothing to do with barrel/sight alignment. Keep shooting, it will line up. It took me a while to get real accurate with the Gen4 G23.
