could've still got a good barrel shooter71, so i'd say use your own judgment. if you're seeing your brass deform or burns on the outside of the case, that would be something to consider, versus the empties looking like all the other "healthy" brass coming out of guns with chambers that fully support the case.

Not all Glock 40's have a bulged casing problem. Mine did. My Gen. II Glock 22 was spitting bulged brass. I replaced the barrel with a KKM match. Complete drop-in. No more problems.

Glock Kaabooms
I have a Glock 20, 10mm. The first barrel Glock replaced due to bulging the brass on factory rounds. The second barrel was much better, but would put smileys on Winschester Silvertips, Doubletap Ammo, and a lot of handloads.
Replaced the Glock barrel with a Barstow barrel and never had a problem since with any kind of bulging of the brass. Reliability is the same as the Glock Barrel. With any Glock caliber operating in 35,000 psi range, I would recommend considering a replacement barrel.
My Glock 21 has never had a problem, but the pressures are much lower.

Re: Glock kabooms
Not a .40, but last year at the range I had a young man show me a problem he was having with a Glock chambered for .357 SIG. It was Winchester ammo right out of the box, but it kept jamming as it fed into the chamber. Three rounds had the bullet pushed so far back into the case neck that there was maybe 1/8" showing. I told him please do NOT fire that weapon until a gunsmith had looked at it. Scared the willies out of me, since he was at the next station.
So I went back to tossing brass with my CZ-52...

Gosh, you guys have made me afraid of Glocks now. I have 8 that I need to get rid of before they blow up. Who wants them? I am afraid to even touch them. Guess I better say up front there are 2 G35s and 2 G23s. I shudder to think how close to the edge of destruction I have been living.

Wise decision. Many, many police departments have reported that both the .40 Glock and those chambered for the .357 Sig emit dangerous projectiles from the big hole in front when anyone pulls back on the little thingy that depends from the middle. Glocks in general are noted for this flaw. So are all other firearms. I've heard of one case in which an experienced ATF agent shot himself in the leg with one. Bad things. Bad.

Yes and no. The problem isn't so much with the barrel as it is with the round itself. If reloading make sure you use good brass, and don't reuse often. Make sure the bullet is set back correctly and I personally would stick to the lighter weights 165 grain etc.
Glocks do not have fully supported chamber and as such the brass is taxed on firing at the six o'clock rear. New brass should be fine assuming the load is correct and bullet setback is ok.
I am not a reloader but I follow a few rules with my factory .40 ammo.
1-I don't shoot 180 grain ammo. I stick to 165.
2-I don't rechamber rounds that have already been chambered more then twice.
3-I tend to eyeball the bullets to make sure there are none that are seated noticeably low.
This is not so much a Glock issue as it is an ammo issue. Glocks design does, exacerbate the issue a bit though.
Still, with a modicum of care, we are talking about pretty low odds that you will blow up your gun. Like, maybe you should buy a lottery ticket if it happens.
Although keep in mind that statistics have shown with Glocks you have a 100% chance of getting one UGLY pistola.

Ooops yep. That is what I meant. Sorry. Suffice to say it, ain't exactly a likely day to day occurance.

Chris, why do you use 165 grain rather than the 180?
The Real Hawkeye

Set back is more likely to cause high pressure with 180 grainers as compared to 165 grainers.
cslinger

As TRH said it is the setback potential. The 180 grain is a big bullet that takes up lots of space in the cartridge. It is much easier to have it push back through chamberings etc. and if it pushes back far enough it creates an over pressure situation.
The 165 grain, or any bullet for that matter, can set back but te 165 grain is smaller and less likely to push back far enough to cause an overpressure situation.

Glocks and Kabooms
To answer your question regarding the 357 sig, The Glocks chambered in that caliber have a very good supported chamber. The is helped also by chambering a 9 mm bullet into a 40 cal chamber. IMHO the Glock in 357 sig is very safe and will not be expected to kaboom lile the 40 S&W. My Glock 22 and 23 have been replace with 357 sig chambered Glock. I reload and use a Lee Factory Crimp on each round , not a chance for a set back. I also use the LFC die for the 45 ACP. [doesn't hurt the accuracy any either] I find the Glock chambered for 357 is one of my favorites. I do have an after market barrel in 40 S&W to use at times, [which is 95% supported and rifled for lead practice bullets] Long live the 357

I just bought a Glock 23. I hope I am professional enough to shoot it!

Hmmm......I always trusted my own reloads far more than ANY factory ammunition.

Glock KBs are bogus
I hate to be real naysayer, but does anyone have the statistics on the number of rounds fired from a .40 GLock verses all other .40 handguns? The KB theory seems to be related mostly to different loads of ammo. Now, given the fact that when S&W started the 0.40 cal craze, and Glock was first issue gun to field over 48000 guns into service, and S&W had a test bed of less than 2000, given the number of rounds fired from Glocks verses all other brands and makes firearms lead to critical failures is not that surprising. Please look at statistics before implying that a single model gun has failure modes that can cause death or permanent injury. thanks

How can one be a naysayer with all the evidence that supports it?
cslinger

Because there is evidence that supports KBs in SIGs, Glocks, Rugers, Smiths, Berettas etc. Hell I have seen a few KB'd revolvers.
.40 is a very hot round with not much room for bullet setback at all in the heavier grains. Hence I tend to only shoot 165 grain .40 in my guns.

If you take care of your pistol and follow the guidelines in the OM you're not likely to ever have any kind of problems with your Glock.
