Glock .40 Phase 3 jam

[Grump]

Once again, I've seen a Glock in .40 fail to fully eject on the first round out of a FMLDF magazine. Not quite a stovepipe because the round was horizontal, but it also did not lock the slide up like the G-19 Phase 3 jams reported by Dean Speir on The Gun Zone.

In testing just a month earlier, that pistol would not "limp wrist" jam with the same ammo until it was held barely tight enough to keep it from dropping from my hand, and it also had to be held offset from the wrist so recoil was not in line with the forearm.

The bummer is my only clue to the jam before [nobang!] is the recoil impulse not including the slide closing normally. No case sticking up into my vision, you know.

Were there any changes to the Glock .40s ejectors? This one has all six parts of the early '90s "upgrade". How does one address this problem?

Glock made changes to extractors on all guns several years ago.
If you have an early gun, no finger grooves on grip, send it down to Glock in Georgia and they will upgrade it.
No more extraction issues.

Are you saying there's an extractor change beyond the one which is part of the "six-part upgrade" described on Glockmeister.com? Mine has that stuff already.

Funny, thinking about it, I have never had my Glock do anything but go boom when I pull the trigger. Have had it for about 5 years, tens of thousands of rounds through it, no problems. Guess I have just been lucky.

Is it a newer model, (manufactured around mid 2003) with the loaded chamber indicator? If it is, it may need to have the spring loaded bearing replaced with the redesigned bearing.

Gen II frame, and as stated before, the six-part "upgrade" is all in. That includes the extractor. No chips, wear, marks or signs of trouble on either the extractor or the ejector, and the spring behing the extractor is plenty strong. I'll double-check for binding on the extractor.

If all you're going to say is "MY Glock has NEVER jammed," well, jammit! Such comments contribute nothing to the discussion. Just because you weren't there when the Perfect Universe was created doesn't mean it didn't happen.

One thing I have to give the Glocksters is their ability to enter a state of total denial. Report of a Glock jam? Never happened; it is a lie. Report of a Glock blowup? Never happened; it is a lie. Report of a Glock problem of any kind? Never happened; it is a lie.

Come on, guys. Glocks are darn good pistols, and extremely reliable. But they do have problems, else why would the company have a service program and continually upgrade the product to make it better?

Saying a Glock failed is not attacking your manhood or slandering your wife; it is only saying that a gun failed. Believe it or not, Glocks are just guns, produced by human beings, not gods, and no human product is perfect. So climb out of "de Nile" before you get too wet.

Ouch, I'm a glockster, glockophile, glockoholic or whatever you want to call it. I've seen a similar malfunction in a friend's G30. There was a small piece of aluminum shaving wedged in behind the extractor. It wasn't getting a good bite on the case. Some type of debris may be in there. Another thing you might want to check is the plunger spring, make sure it isn't weakened. Glock .40s shoot brass out pretty hard, if the cases are just dribbling out, something isn't right. Is it only one type of ammunition or a variety?

If you are having any malfs with a Glock, the first thing I learned you should do is detail strip the slide.

I have a G30 that wasn't reliable until I did so.


Hope this helps.

Thank you for the more recent posts and suggestions. The slide was detailed a few months ago for new FP block and spring, so I will check to see if any grits got into the works. Will post results/follow-up after I gettaroundtoit.

Glocks can be very finicky about their slides, to make a vast understatement.

My 30's slide was immaculate compared to my 27's slide, and I haven't ever had a malf with the 27.

I was quite surprised to see how filthy the 27's slide was; all sorts of junk around the extractor, etc, but still no jam.
