Glock's unsupported chamber issue.

RePete said:
All the .357 SIG is , is a necked down 40S&W, so the excessive wear is crap.:bsFlag:

The 40S&W does have an unsupported chamber, and today, there doesn't appear to be a problem with the gun, UNLESS you overload it.:slap:

As for reloading, I reload for my 17, Pops reloads for his 17 and 35, SteveS reloads for his wife's and his own 17's. You just should use jacketed or plated bullets.:dancingbanana:

Do I like my Glock? Hell yes!:shotgun:

I have no personal experience here but the Glock .40s have the reputation of having a service life averaging only 20K rounds, with the more mechanically violent .357s going away even sooner than that. I'd be taking that into consideration a lot more than an overhyped kB issue.

fwiw:

i have put well over 10,000-12,000 rounds through my G22, and at least 4000of those have been handloads (FMJ only). I've put plenty of premium defense ammo through it, and whatever else is cheap and available. the gun hasn't blown up. it gets maintained and cleaned when i have the time. i also have a 357sig barrel for it, with perhaps 700-800 rounds launched to date. zero problems. zero malfunctions.

if you're looking at either the .40S&W and the .357SIG, just buy the G22 and a .357SIG barrel, the two are interchangable and therefore u can have both calibres! and ive never had a problem with my G22 to date

cheers!

There are Glock .40's with more than 20K rounds that are still running fine.

There are also K frame Smith .357s that have that many Magnums through them that are still holding up, but that's not typical of them, same deal with those particular Glocks. Of course 20K rounds for most shooters is a lifetime's worth and then some, and then some more.
 
FWIW, I seen a G22 kB first hand. It was during my Probationary period at BRRC (PPC night IIRC). Maybe they are a member here, donut know.

There is obviously less margin for err in the .fowdy Glocks. All my .40 brass bulged, although the gun functioned perfectly every time (only used Wincleans). My G17 cases don't bulge at all, and 9mm is the same PSI as the .40.

I would much rather have a Sig P229 for my next .40.
 
If you are concerned about support you can buy an after market barrel that has more support and rifling for lead bullets.
 
i am an expert at blownin up , glocks , the unsupported part was were the bullet let go , but the ammo was the problem , someone elses loads, not chamber checked and most likely had a crack , my fault.!!!

LOAD MY OWN NOW , CHECK EVER ROUND .
no problems
do learn the proper way to load as your life and hands are at stake.
trust me.

love my glocks:evil:
have pics but wont let me post.
 
ive shot over `100k of relods in glocks in th last 10yrs no problems
ive loded at leat 50k for my shooting partners that all shot glocks.
last year i shot 9k of reloaded ammo in one glock befor i switched to an svi for ipsc, the svi spends most of its time with me working on it.
I would trust my life to a glock g17 with win stx ammo.

I've put thousands upon thousands of factory and reloads through my G22, no issues whatsoever. Its not an issue as far as I am concerned. Stick to the manual when reloading and don't push it and you'll be chiming in on the next thread about Glocks and their unsupported chambers.
 
I wouldn't buy a Glock, but not because of the supposed kb issue, the "short service life" or any of the other things you see written. These things are entirely in the control of the shooter. For some strange reason, many people with a Glock think they are gunwriters and set out on personal odyssey's to see how far they push the envelope. Treated with the proper respect Glocks are simple, reliable and safe. The only reason I wouldn't buy a Glock is that they don't fit my hands properly.
 
I have seen reports on police forurms where they where unhappy with the Glock .40cals with rails. Seems they were having a high number of failures to operate with lights attached and a poor response from Glock. They suspected the lights kept the frame from flexing as it should. The problem was more common on .40cal Glocks than the 9mm version. I also know of 2 people that had a casing rupture on a .40cal Glock.
 
I bought my Glock 17 in 1988. It had at least 20000 reloaded rounds though it before I sold this gun. I never had a single problem with any unsupported chamber issues.

I sold the gun only because I wanted something different, a CZ85C.

So far the CZ has been great. That said it has many rounds to go before I will compare it to the Glock.:D

That's a bummer, because just about anyone can be taught to shoot a Glock well...

:eek:
Well I`ve never put anything on my glocks, but that does sound like a quite strange occurrence. Anyone else heard of this?
 
Buy a G20 and a quality drop in 40SW after market barrel. The G22 is built on the same frame as the G17 and the G17 was designed for 9mm. There are thousands of G22's that have never had a problem but I don't want to be the one to find out different. I would rather own the real 40cal....10mm....and a G20.:cool:

As long as you have hands like baseball mitts yer good to go... :p
 
G34 some years back. Commercially reloaded ammo (well known "local" commercial reloader).
Did not damage the gun but blew the mag out of the magwell and singed the shooters hand in a couple places.
I have a G22 and shoot the same ammo... have not experienced a KB yet (touch wood).

I was thinking of buying a Glock and did a little asking around as well as some reading. I wanted something as close to my 357 Magnum as possible and was told the model 31, 357 Sig. would do the job however this calibre in a Glock would cause excessive wear to the gun. So then I considered a .40 s&w. I was informed that this was the worst choice of calibre because of the unsupported chamber. I pulled some pictures of off the web and sure enough the .40 had more brass expossed at the 6 o'clock position than did the 357 or 19mm. It also showed pictures of Glocks that had KB'ed. I went on to read that one should not shoot re-loads or commercially reloaded rounds. This was the clincher as I cannot imagine buying factory ammo. That would sure cut dowm on my shooting. Well I guess I'm not so excited about the Glocks now. Any comments would be welcomed.

I don't even care for Glocks but I don't believe the unsupported chamber argument has much support,lol. Glocks are built to take a beating, I just wish they had a bit more in the looks dept. I may get one in .40 when I get to handgun # 10. Only a few away from that that now thanks to too many nice guns in the EE on this site.
