Massive Glock-20 frame failure!

A gun barrel from an unknown maker, is this common?

I ordered a kkm barrel for my 20, hope it says kkm on it.

I do think federal sells barrels with other names on them. So some have names on them.

I am wondering about the "it happens mostly with 357 sig" remark. The 20 can only have 357 sig in it with an aftermarket barrel. The smaller gripped glocks come with 357 sig stock. The two big gripped ones are 10mm and 45 only.

I come back to the round being defective. Just like most here have.

And is gun broker one of those auction sights? If so, the barrel could have had known problems or the previous owner had a bad round already? In this case a trip to the race engine shop for a magnufluxing would have helped. Course then you would not have saved any money over getting a real barrel with a name on it.
 
Ziggy:

Thanks for the update.

keep us informed.

I own and shoot a Glock 20 with a KKM 6" hunting barrel, and a pair of stock length Federal Arms barrels in 40SW and 357 SIG. Three calibers, one gun. Factory or reloads. I shoot cheap.

So I'm interested.

But as always, I think you're better off reloading your own than taking the risk with all of this great "factory" ammo. Speer, Wolf, Winchester, and the like.

if anything happens, you at least know, it's you.

Yeah, all my ammo is factory made, I made it in my high tech residential manufacturing facility on a state of the art Dillon 550B reloading press.
 
Let's see...your friend bought a aftermarket barrel of unknown manufacturer, from an auction sight (which means it could be very, very used) and you don't think it's the barrel. Sounds like a good example of "let the buyer beware" to me.
 
my friend purchased the barrel on gunbroker, so has no idea who the manufacturer is.

Did anyone else LOL when they read this?

Just out of curiosity, how did a chunk of the slide get blown off if the barrel is still ok?
 
Here's A WHAT If? For Ya'll-

Federal 10mm brass when reloaded warm has an annoying habit of spliting in two and leaving a portion of the brass stillin the chamber.
Ya with me, the gang swaps the 10mm barrel back into the G-20, someone stuffs a mag in that still has a round or two of 357 SIG and chambers it into the 10mm barrel that just happens to have a piece of brass left that allows the SIG round to chamber just far enough for the gun to fire in an "out of battery" condition...BOOM!!!
It wasn't that long ago when the IDPA had three .40S&W blowups with one fatality.
These folks were lucky
 
Just a couple of comments:

1. If that "Gunbroker" barrel was previously used to fire lead (unjacketed) reloads, that alone can cause a KB - in almost any caliber, but especially in the .40 S&W and the .357 Sig.

2. I'm probably one of the few posters here who has personally watched a Glock KB and has been through the factory inspection/replacement process.

On December 30, 2001 my son's G-27 (.40 S&W) KB'd on the final mag of the session. He had been shooting range ammo (Blazer 180 grain) and decided to shoot his mag full of "self defense" ammo before we left (the ammo was several years old, and he planned to buy a fresh box as we left the range).

The third round in the mag KB'd. We found the empty casings of the first two rounds and the case head of the third round. This stuff was Federal Hydra Shok ammo that he had bought at a gun show.

The mag blew out, the extractor blew out (never found it), the extractor plunger slid out, the case split and jammed in the chamber and the hot gas/possible piece of casing hit his trigger finger leaving it pretty sore.

He had bought this Glock new and had never shot any reloads in it. Also, the round that KB'd had never been chambered before (he knows not to repeatedly rechamber a .40 round). So we sent it, and the empty casings to Glock for inspection, and then began doing some research on Glock Talk.

What we learned (and Glock confirmed this) is that Federal made a batch of weak .40 S&W cases a few (5 or 6 ?) years ago. All of this bad ammo was stamped "F C". Federal never recalled this ammo, and apparently as the word got around, some people just sold it at gun shows to get rid of it. The new, "good" ammo is stamped "Federal" rather than "F C." Not all of the "F C" ammo is bad, but all of the "bad" ammo is apparently stamped "F C."

Glock confirmed that the Federal ammo was the problem. THEN, to keep us out of the middle of any dispute with Federal, Glock shipped him (on February 6) a NIB Glock 27 and said they would seek reimbursement from Federal. This is very similar to the way Ford replaced defective Firestone tires on some of their trucks.

Glock's customer service staff was very responsive and very professional throughout this process. I have no way of knowing what their response would have been if they had found aftermarket parts in the weapon or if this had been a pistol in which unjacketed reloads had been fired.

My experience with bullet setback wasn't with a Glock, but it was caused by a mag.

I was shooting a Romanian SAR (AK). About half way through a 30rd mag, I had a jam. Somehow the bullet was shoved forward, but not into the chamber.

I rechambered the round without looking at it. -NOT VERY BRIGHT!- :eek:
When I pulled the trigger, the report was too loud, and the recoil was too stiff, and the gun was jammed again. I dropped the mag, and that was when I noticed that the cartridge that had jammed was shorter than the other rounds.
The bullet was jammed way back in the case. I'm lucky the gun didn't blow up.

It turned out that one lip of the mag was deformed. About half of the mag would empty just fine, then it would jam. :confused:

I wonder if the gun in question had jammed prior to the KB?
 
KB's

Bullet setback.

Don't care who's barrel it is when this happens...........twenty zillion PSI (measured) is taking it apart.
 
bluedot fills the case like accurate #9 in the .357 sig as well.no bullet set back you cant even seat the bullet but so deep the powder is in the way.
 
I just want to know how in the he!! can the frame and grip be blown up if the barrel is intact. Sounds to me like a round blew up in the magazine;) Or maybe it just blew up in cyberspace like so many other Glocks. Of all the Kb's I have seen actual pictures of, the barrel hood was split or pealed back and the ejector was blown out, sometimes with minor cracks in the frame or slide. Seminar caller??

From what I understand about reloading, that is when bullet setback is more dangerous. When the case is full of powder up to the base of the bullet, and the bullet gets pushed back into the powder, the powder becomes compressed. If I'm not mistaken, and equal amount of compressed powder will make more energy than an uncompressed amount.
 
Actually compresed powder isn't necessarily a big deal. There is such a thing as a safe compressed load. Drastic amounts of setback can cause drastic pressure spikes, however.

The paranoid fear of reloading and aftermarket barrels on the part of some people is kind of interesting. I Hear a couple of internet forum gripes and suddenly I'm dancing with death, a Bar-Sto barrel and a bucket of Accurate #7. :p
 
Zigo,
I agree with you...if Glock agrees to fix/replace the "used--re-barreled w/off-brand barrel" gun...
Geesh, that's fantastic!
I too have had great success with Glock's customer service.
The guns are darn functional and reliable...but when something happens, they step right up.
I own several Glocks, but I tend to shoot a variety of guns...when someone points a gun at my head and makes me choose ONE handgun to take to the woods to survive with...it'd be a Glock.
Not pretty...but "stupid simple reliability".
