So I just finished a two day course and put about 1000 rounds through my G19. I was expecting a flawless performance from the gun but ended up having a few problems. One the first day, I had 3 stovepipe/double feeds over the course of the day, and one in the middle of the second day. While I appreciate the malfunction practice, wtf? The gun is less than a year old, and the mags were new, with maybe 1000 rounds through it before the class. After the first day I took it home and gave it a good cleaning, but still had one double feed the next day. Id never had a problem with it running reliably to this point, but I hadn't run it that hard. I was thinking it might be a bad extractor, but since it wasn't a consistent issue, maybe it was ammo or random occurrence. I know it's hard to diagnose without looking at it, but any thoughts on what might be causing the problem? Thanks.

How many mags do you have in rotation, and have you been marking them?

Are you running the factory recoil spring system, and is it within spec? (eg, passes the recoil spring test). This is probably a yes, as you indicate the gun is pretty young.

You didn't specify the generation, either. Stovepipes is often a Gen4 thing, but there were some runs of Gen3 G19s that had a stovepipe issue as well, but not sure if the range is documented or not.

Also, independence is fairly shitty ammo, I would segregate it out and set it aside and shoot it separately.

I'd clean everything, test the recoil spring, and run some non shit ammo through it. If it jams inside of the next 2000 rounds send it back to the factory. There is no way a G19 should be that unreliable. I used to shoot mine until clods of dirt were coming out of the ejection
port. [laugh]

I was running 3 factory mags, and no, not marking them, so I'm not sure which mag was in when it happened.

Yup, the spring is stock, and I assume with in spec.

It's a Gen 3. I've put 2-300 rounds through it at a time before with no issue, but it was never a mix of manufacturers.

I didn't realize it was crap. I had a hunch, but it's a Glock, right? That said I have run independance through my G34 without a hitch. Maybe the 19 is more particular.

That's my plan for right now. I'm not going to be able to run that volume of ammo through it again for a while, but I'll keep an eye on it at the range. I was surprised to have any trouble at all. The bit of reading ive done this morning suggests that with a total 2k through it and 4 failures its probably too soon to send it in without a little more evaluation. If I see it happen again, I'll give Glock a call.

Every time I have had a failure in my glock its one of the following: bad mag, my own reload, or cheaper ammo/mixing ammo.
 
Independence is horrible ammo. You'd even be better off with Estate 9mm ammunition. It could be the extractor but the Gen 3 extractors have been pretty reliable. Can you give us the number off the extractor?

Sounds like the G34 torture test you did. [rofl]
 
I've trained a lot of Soldiers and a few Police officers over the years, regardless of how confident people are, when training they generally try to focus on thier weak points specially after doing a lot of shooting,,,, they (get sloppy or complacent) start to neglect some of the simplets fundamentals. The first thing I watch or ask them when this happens is thier grip/wrist. "Limp wristing" (not keeping the wrist stiff enough) will absorb the recoil that is crutial for the cycle and stovepipes are a classic indication. Sometimes the slide will not cycle far enough to catch another round and you just end up with a stovepipe and sometimes it will cycle just far enough to catch the next round, but not eject the empty. My appologies if this is beneath your skill level,,, but it happens to the best.
Hope this helps
 
I hope you don't trust your life on that gun, you might as well get a gun that cost half as much like a sigma or an sd
