Mechanical
If 3 people shoot it and it malfunctions, It's not the shooter.
If you change the ammo and it malfunctions, not the ammo. Do this next.
Get a different magazine and try it. If it jacks up, it's not the mags.
Mechanical is the last resort, and more often than not, it's related to a bad recoil spring. There are, on rare occasions, mechanical issues related to the barrel. It's statistically possible that you have an out-of-spec barrel, so if you know anyone with a G19 or G17, borrow their barrel and swap it out with yours, shoot it, and see if the problem replicates. If it replicates, I would bet it's a recoil spring issue. If you have a buddy with a G19, swap the recoil springs to see if that fixes it.
Otherwise, contact Glock and have the guns serviced.
Fair enough but I'd add.
1. I've gone through the Glock Armor program, YouTube is pretty close to the same thing. And comparing it to any significant gunsmith expertise is the equivalent of being able to change your oil in a car versus a rebuild a engine. Glock basically teaches how the mechanics work but very little about fitting or adjustment or even the real geometry of parts. If something is not right - replace it.
2. Clean it, who knows how long or where it has sat. The purest will say run it dry out of the box, but a good cleaning and lubrication has solved well over half the performance issues I've seen on ranges.
3. WWB is not great ammo - but one thing it is not is weak - it can be counted on to be well above minimal charges as a opposed to companies like Fiocchi that makes much better ammo but it is notoriously conservative. That is why I said try WWB, then a good quality defense ammo.
4. 3 shooters means nothing, 3 bad shooters can all have the same poor grip. As I mentioned find someone that shots Glocks and let them give it a run.
5. Mag could be a possibility but I would have hoped he tried the other mag - if not he needs more help than a Glock that has FTF/FTE issues.
6. If all else fails or you don't want to try anything else send it in - odds are they will clean it, run some ammo through it, find nothing wrong and send it back dirty. And all you loose is months waiting for it.
