Strange glock failure.

I have a number of glocks and they have all proven extremely reliable. Just purchased another 19 and had a very consistent issue straight out of the box.

Gun would fire the first round and load the next one out of the mag but failed to reset the striker. hmmm ok. I was using light target ammo in a new tight gun (WWB 115grn) Let's step it up.

Ran half a dozen Hornady critical defense 135 Grain +P all with the same failure every time. Also tried two other known good mags.

Figured that may help but I was out of time at the range so went home. I detail stripped the slide and ran it through the ultrasonic cleaner. Light oil on the rails and back to the range today. New issue.

Now it resets the striker but it's failing to go all the way into battery so I'm getting light strikes right on the edge of the primer. ??? Why the heck is the pin able to get to the primer with it out of battery!

OK more trouble shooting. No I'm not limp wristing it. Used three other glocks in 9mm, and beretta 92 today all with zero failure. Tried magtech, blazer, hornady, SB and wolf ranging from 115 to 147 and all had the same issue

I also tried mixing and matching parts from two other 19's to see if it was guide rod / spring, frame,mags etc. With any combination of parts that barrel in that slide failed 90% of the time.

This is in no way bashing glocks, I do like them. Just an observation of an issue in a mechanical device and a gentle reminder to always test out your defense weapons. Pics below

All Glocks will fire out of battery. They just usually make it into battery so it isn't an issue. When it is an issue and it's .40 - kaBoom.

It seems like something is keeping the striker from cocking completely, but you check the slide. So you need to start looking at everything that can interfere with the slide going forward - recoil springs, barrel to slide fit, barrel to locking block, FPB.

Gen 4s have had problems with their recoil springs. Personally, I'd call Glock with a the gun nearby or at least a good idea what it's doing and the SN.

I would not be inclined to shoot it anymore.

Gen 4's did but I believe all mine have the latest guide rod and spring. As part of the troubleshooting I tried it with a known good spring assembly from my other 19 and it still had the same failure

I'm leaning towards the dimension of the barrel in the chamber are just won't play nice with the slide

As Tahuna said everyone has a lemon now and again. I've had enough guns over the years that I've seen issues with most brands at some point or another.

Will keep everyone posted on Glock's response to the issue
 
I would rack and dry fire the gun a few hundred times when you are bored watching TV or something. Something might be slightly out of spec, if you feel like trying to correct it yourself. However as others suggested, send it to Glock via the store you purchased it from, and it should come back right as rain in a week or two.
 
OK. Take a look at the following items.

1. Look at the FRONT of the barrel/chamber hood. It is a locking surface. Make sure it is clean.

2. Look at the corresponding surface of the front of the ejection port. It is a locking surface as well.

3. Clear the pistol; now, remove the slide assembly. Look at the locking lug on the bottom of the barrel. Make sure it is clean.

4. Now, look at the locking block in the frame. Same thing--make sure it's clean.

5. Check the extractor. Is it bent inward? This can be caused by dropping a round in the chamber, and slamming the slide. Glocks, like a lot of semi-automatics, have a controlled round feed--the pistol is designed to be fed from the magazine. If the round goes in front of the extractor, the gun can be held out of battery.

6. While you're there, check the extractor for proper function.

7. Take a look inside the barrel. Is there a burr in the chamber? Check this with the barrel out of the gun by dropping a round in with your fingers. Does it chamber fully?

8. Check the trigger assembly--especially the back of the cruciform (this catches the striker), the connector and the striker itself.

If all of this looks good--well, then, it sounds like a trip to the factory might be in order.
 
It's headed home to Georgia for a checkup

Ok huys I've looked at this thing for a couple days. Detailed stripped again on the bench magnifying glass etc.

Chamber is fine all ammo passes the plunk test.

Different slide works fine on the "problem" frame.

Went as fast as using Dykem blue layout fluid to see if there was any uneven wear in the barrel lug or barrel to slide lockup. I can't see a single thing wrong with it!

Called glock and they said either ship it to them (on my dime) or find a glock armorer local to me. None are convenient so I'm headed to fedex to ship it home to GA. Will keep you updated on what comes back.

Slightly disappointed that I have to ship it at my expense. The couple times I've had guns serviced was my walther (through S&W) and ruger, they both send call tags so no expense to the consumer for shipping. Curious to see if they toss in a free mag or the like to take the sting out of it.
 
New Glock + fail to fire = return to Glock.

Let them deal with it. Warranties were included for a reason. Any self-repair does not guarrantee you have found the root cause.

Maybe they will reimburse for the shipping? I would certainly pitch a fit about shipping when they get the diagnosis.
 
Glock's policy currently is that the owner is responsible for shipment to glock and then they pay return shipping. Again not the end of the world by any means. Thankfully I have a fedex account so it costs a little less then it normally would.

I totally agree that a firearm is too important of a tool for me to say I THINK it's fixed. I wanted to know the failure just because I like to understand but unless it was something glaringly obvious such as the guide rod I firmly believe it should be serviced at the factory.
 
I may have missed it, but nobody seems to have mentioned looking at the striker safety plunger and spring.
Maybe it's gooked up with shipping grease or something.
Also check the end of the trigger bar, where it rides on the connector, for rough surfaces and lack of lubrication.
And make sure the trigger return spring is ok.
All of the above could interfere with the trigger and striker reset.
 
G willikers I did detail strip the slide and ran it through a heated ultrasonic cleaner so that baby is sterling clean. And not much of a black powder guy!

Dirty Harry I'm an equal opportunity gun nut I've got some HK sigs and FN's all the way through some little keltecs and naa revolvers
 
I shipped a glock back to Smyrna a month or so ago and they sent me a paid return shipping label. Did they just recently change their policy? There's no way you should have to pay to return a brand new defective gun. I would call back.
 
Huh...

The guy I spoke with in the service department said that it is company policy that I had to ship it back. I just said ok, maybe I should have challenged him on it. Poo.

Well I paid for it and It's already on it's way back. Now I really hope they throw in a mag or two!
 
I'd call them and ask why they call tag some customers' guns, but not yours that is unreliable and firing out of battery. Then ask them to through in some mags to make up for it.

Oh yeah, I love them all too. HK's I just tend to like best. I have a Glock and plan to have a couple more.

If this would have happened to an HK, the Glock boys would be all over it. :rolleyes:

I sure hope Glock makes it right. Thats horrible if it is a fault of their own and they charge you for shipping.
 
Glock - Firing Pin Strike?

I've owned and fired perhaps 20 or so Glock Models, all Gen.3 and Gen.4's.
I don't recall ever seeing a firing pin primer strike so far "off center'. Perhaps I just haven't noticed, as I've never had a failure to "go bang" in many many thousands of rounds. Does anyone else think it odd?
