I just purchased a new Glock 19x. Took it shooing and unfortunately, after shooting at least 100 rounds through this gun, it was the jam-o-matic.

In the first six magazines every single round jammed. I do have pictures of the jams and it happened with different ammo (All factory ammo and have included pics of the ammo) and different mags (the ones included with the new gun and another I knew to be good). It should also be noted that the slide never locked back.

I sent it to Glock, they had great customer service by the way, and they sent it back and told me no issues were found.

I took it out shooting and again and it jammed 3 out of 10 rounds.

I shot it the way that it was sent it back to me but did not seem to have a lot of lube on it.

I put more Lube on it and the second time I did not have any jams.

It is my best guess that the recoil spring is too stiff and the slide was short cycling.

I wrote Glock and they said to put more rounds through the gun

Anyone have any similar experiences with the Glock 19x. Any suggestions?

Glock doesn't lubricate their firearms when they're sent out. Glock puts anti-seize in them, which should be removed, and the pistol lubricated, before firing.

I've had no issues at all with my G19X.

Your pictures show two different types of malfunctions; a Stovepipe, and a feed issue where the round appears to be hanging up on the feed ramp.

As a general matter of course, stovepipes can be one of several issues, including extractor, ejector, and user. The stovepipe is the classic "limp wrist" malfunction. On the Glock, it can also be attributed to an improper extractor installation (plunger not installed correctly), and a bad ejector.

The feed issue speaks more to the magazine. It could also be lubrication. Was this the magazine one of the factory magazines that came with the pistol? How many rounds into the magazine did the problem occur, and how many were in the mag?

My 19X will run all day on any kind of ammunition, including some of my longer flat-nose reloads, and low power, low velocity rounds.

I'd look at lubrication, first. Despite the classic drop of oil here, drop there, I use grease on the rails and striker catch, firing pin block lower surface where it meets the trigger bar, and on the spring assembly and under the barrel. I put oil on the trigger pivot points and internals. I use a bit of grease on the disconnector, too.

When dry firing, with the sights aligned, does the trigger feel stiff, and is there movement of the front sight when you press the trigger?

What kind of ammo were you running?

Does the extractor move back and forth freely?

I know this is a stupid question and please don’t think me condescending but do you have a firm grip on the gun. Could you be inducing the malfunctions with your technique. Again no disrespect meant in any way just throwing stuff at the wall to see what sticks.

Clean and well lube the gun.
Lock the slide back and leave it locked back for a couple days or so.
Work the slide/dry fire
Run a box or three of hotter and or heavier for caliber ammo (124g NATO, 147 grain, +P or defensive ammo etc.)

After doing all or part of those things re-assess.

I’ve seen similar issues in other 9mms from companies who build them for military or LE. They tend to be tightly sprung and might take some time before they will run 115 grain crap (if that is what you were running). Early on they will also exacerbate any improper grip.

Also these days it’s not out of the question you had a bad batch of ammo. I mean ammo companies are kinda running full tilt and I am sure quality is suffering.

Again not saying ANY of the above is the issue but they are all things you can tinker with yourself to suss things out before going back to mailing to the mothership.

Is this a Gen5? I have issues with a gen5 17 and the slide not locking back on an empty mag. Its me, not the gun. I am somehow pressing one of the ambi slide lock levers. I have had other shoo the gun and had no issues. Can someone else shoot the gun? Also try to intentionally change your grip and keep your hands as far from the slide locks as possible and see if the problem is still there

I wish I would have got a gen4 not 5.

Depending how mechanically inclined you are. I’d do a detailed field strip of the slide. I’d remove the rear cover plate and take out the slide parts and clean everything really good with patches and Q-tips. Particularly the channels for the extractor and extractor plunger assemblies. The guns are all now sent from the factory with a preservative which may be gumming up and causing the extractor to drag or bind up. After thorough cleaning lube it. But not the slide internals. Only the rails and barrel surfaces per the manual. Had a similar problem with a gen3 G26. It disappeared after tear down and cleaning. Depending what type of lubricant you are using can also cause problems. I accidentally mixed rem-oil which is petroleum based and fireclean, which is vegetable based on my Steyr m9a1, which is similar to the Glock. The lubricants are incompatible and turned to jelly. Enough that it slowed the striker and didn’t fire the round it jammed

I had the same thoughts. When the OP mentioned that the slide never once locked back, it's the first thing that came to mind. Glock says there's nothing wrong with the gun, and it's always a possibility that it's user error until that's definitively ruled out.

My brother had a Gen 4 19 for years, and the slide wouldn't lock back for him - it always rode home on an empty magazine. One range trip, he brought that 19 and I brought a few of mine, and a whole pile of magazines. He mentioned the failure to slide lock, and I decided to test it. We loaded every single magazine we had (between the two of us, it was probably twenty mags) with a single round, and I shot the pistol instead of him. It never once failed to lock back.

Magicman, have you had anyone else shoot the gun in the course of your troubleshooting?

To eliminate or confirm this, have someone else shoot the pistol, same mags and ammo see if it continues to happen.

Also, if you're shooting WWB 115gr, that could likely be the issue. It's notoriously weak and more than a few people with new pistols have gone down the rabbit hole chasing a non existent problem.

Is the slide stop engaged when it jams?

This.

Shoot with your thumb off the gun or one handed. See if the problem persists.

The one time I shot a new Glock 19 it jammed several times until the owner pointed out I was limp wristing it. Once I held it 'tight' it functioned fine. I suspect if I put 100 rounds through any of my pistols my 'wrist' would be a little tired ....

Accidental double post. Read mine below, disregard this one.

Sorry I cannot be of much help with your situation. My G19x ran reliably out of the box and has continued to do so. It gave it 8 full 17 round mags and both 19 round mags when I got it last May with only a bit of CLP and it ran great.

Looking at the type of malfunction it seems either ammo related, extractor related or something is off with the slide geometry when it cycles.

In today’s ammo starved times, this may be a bit painful but have another shooter try your G19x with the same mags, ammo and lube combo and see if it acts up.

If you can only find that kind of ammo, consider a grip sleeve or different backstrap for a better hold.

I have a pistol that I shot well with checkered aluminum grips. Found a deal on some custom smooth grips. Turns out I couldn't firmly grip the pistol one handed as well as I needed to because I couldn't get a firm enough grip for it to cycle properly. Later I put the old grips back on and the problem was solved. The grips were sold immediately. I wasn't limp wristing (it was a Desert Eagle with 1/2 inch bullets).

Let us know what you find out.

For those having issues with no slide lock, kagwerks makes a lifted slide stop lever.
Some coworkers use them.

I don't have one of those, but my friend does and his first day he put 500 rounds through it with no problems so not sure.

Glock will always stand by their product in my experience so if something is wrong they'll fix it.

Any mods to either the pistol or mags? Check the slide stops spring seating, remove it from the frame inspect and reinsert. Maybe replace it.

Hi guys. Thanks for all the replies.

Lots of questions in here. Hopefully, I will address them all. Regardless. I appreciate the feedback.

Those of you who have suggested lubrication.

I did Lube it very well before I shot it the first time. When I got it back from Glock they had stripped it of the lube, but I could smell what I thought was the CLP.

I shot it that way the first time. And as I said above, I did lube it with grease and oil. It seemed to alleviate the problems. I do have a ultrasonic cleaner, I am inclined to put it in there get all of the preservative out of it, and then relube it.

As for the slide not locking back, it would not do that before I sent it to Glock. When I got it back from Glock and I lubed it, it would lock back.

As for the ammo I am using, I did try it with Winchester white box, American Eagle 124 grain and gecco 124 grain. Before I send it to Glock all of those jammed

Before I sent it to Glock, I did try all of the magazines that came with the gun plus a magazine from a different gun that I knew was good

I'm not smart enough to know about the extractor. But I will look at it

It is a Gen 5. I do have about seven other Glocks. And have never had an issue with any of them. I'm not saying that rules me out. I am just saying it is unlikely.

To be fair somebody asked about a gen 4 vs a gen 5 gun, this is the only Gen 5 Glock that I have, everything else is Gen 4

I will try a different back strap or maybe asleep just to make sure that it's not me limp wristing it or not holding it well enough.

I did have someone else shoot the gun at the time before I send it to Glock and they experienced the same problems

For those who are telling me that it could be me and we're afraid they were going to offend me, I understand and no offense taken.

I also like the idea of locking the slide back overnight or so. I do suspect that recoil spring is very tight. As I do feel the slide was not cycling all the way

I hope my information helps and thanks for all the feedback to date

Sometimes you can get a bad Glock. I had a G34 Gen 4 that had problems that even the Glock rep recognized was bad (stovepipes, extractor etc). Tried everything to fix it.

We sent it back to Glock. I received a completely new and different G34 Glock back from Glock. Good customer service by Glock to make it right.

Thanks. I will take it out again. I will lube it good and maybe even take some vids. See what happens
