I took it apart and cleaned it in the ultrasonic (complete tear down) which didnt seem to help. Being a 1911 guy i have no idea what the issue is in a glock. I am guessing recoil spring getting weak and/or extractor wore or bad. I have maybe 1000-1500 rds thru it. standard velocity magtech, federal and fiochhi 115g ammo.
The only real difference between your 1911s and Glock in what you described is that limp-wristing is
marginally more possible on a 1911. But I think you can strike that off as a possible cause.
And since you've been using a variety of different, standard-power, factory ammo, I'd say that gets dropped off the list, as well.
The next least-likely cause is probably kick-back or spin-back, where the ejecting case bumps into something on its way out and gets blocked back in as the new round chambers. The reason every modern 1911 has a flared ejection port. But unless something has really gone wonky with the slide on the Glock--something that would readily visible--I doubt that's it either.
If I were to take stab at diagnosis, I'd say one of two things: the extractor itself or the extractor spring and/or depressor. My money would be on the spring and/or depressor.
Almost certainly isn't the recoil spring. If the recoil spring is at fault, stovepipes usually occur if the spring is too heavy, causing the action to cycle too fast. A spring with 1K to 1.5K rounds through it almost certainly won't be at fault. I'd also think the magazines aren't the culprit, either. Stovepipes happen on the back-end of the cycle; in other words, the new round is coming into the chamber okay, but the old one ain't gettin' out in time.
If the extractor itself is damaged, you should be able to see that pretty easily, also. If you haven't damaged it with a tool or with a bunch a of really tough steel-cased ammo, that wouldn't be my next guess.
Since you said you're also sometimes getting a failure to extract, I'd say the easiest thing to try would be replacing the extractor depressor and spring. You can get the unit as a whole for around $13 or $14, so I personally wouldn't bother with just the spring. You can get the little bearing piece that holds them together for about $2, if you want. At around 15 bucks it's cheap to try and, if it doesn't solve it, you now have a spare.
As always, my opinion is worth every single penny you paid for it.
Edited to add: Found a photo of a new Lone Wolf G26 (but should very nearly identical to the G19) extractor (on the left in the pic) and a used but still serviceable stock extractor. Too large to post inline, so here's the link:

Also, a stock extractor looks like it's about $18, if you want to try the whole assembly at once. I didn't check pricing for the Lone Wolf or others.
