G19 Gen4 Frequent Jamming
Hi all, I'm looking for some guidance on a jamming issue. I have a Gen4 G19 that was purchased new and so far has probably 800 rounds through it. I've been having a frequent failure to feed issues where the next round from the magazine is getting hung up on the returning slide. Each time this happens the slide pins the round against the barrel which results in malformed or damage to the bullet casing (which is a bit scary with a live round). When I first approached my local armory about this (where I bought the pistol) I was informed of a Gen4 voluntary recall for the recoil spring. Sure enough the recall fit the symptoms of improper cycling. So I underwent the spring exchange thinking it would fix the problem. No luck, the problem persists. The failure to feed is now happening once every 6-10 magazines or roughly every hundred rounds. I use only original Glock magazines and new FMJ ammo (no reloads). I've also cleaned and lubricated several times with no change in the issue.
This is my first Glock pistol, and sure every firearm jams from time to time, but something tells me this is abnormal. I thought Glocks were the worlds most reliable pistol? I've read/seen examples where they've been dropped out of an airplane, dragged behind a truck, buried underground and in all examples continue to fire reliably. Did I get a melon or is there something I'm doing wrong?
The most recent jam was today at the range and I snapped a couple pics:
