Curious about Glocks
I am curious I have owned 3 glocks. I currently own HK USP Compact .45 SS, G21, G23, and a G27 all made after 2001. I am just wondering I have seen alot of articles(older articles) about glock kabooms(as they call them) but never have had a problem with one(jamming or anything). I have had misfires but when I took the shell out the firing pin had hit the primer so I chalked it up to bad ammo. Is there still an issue with glocks or has this since been resolved. Only reason I am curious is because my buddy had a POS Talon P100 blow up in his hand I mean the slide broke completely in half. So I know the threat is real, but in no way am I comparing a Glock to a Talon. Just saying it can happen. SO is there any truth to this rumor? I don't shoot reloads, I use FMJ bullets for target.

My understanding is that the biggest area of problems are with the 40 cal. Im not an expert but I did try something I was told and I see an issue. Take the barrel out of a glock and drop a cartridge in the chamber. Do the same with an HK. The Glock has some area at the base of the brass that is not "covered". This is the area that is weak. 0 -
It ain't just Glockenspiels! Any .40 that has an "unsupported chamber" could KB with any ammo. The portion of the case that gets stressed is by the case head, maybe 1/4" forward of the rim, and if not fully supported by the chamber, could KB at the next pull of the trigger.
The same is true of any caliber semi-auto with an unsupported chamber.
If you know it all; you must have been listening.WEAR EAR PROTECTION!0 -
40S&W is a high (for a pistol) pressure round, combined with the unsupported chamber, can potentaly lead to problems (regardless of gun maker). Most of the reported failures have been with reloaded (read preveiously fired in a unsupported chamber) ammo, although there was a batch of 40S&W factory ammo (since recalled) that had thin case heads.

As stated, it's mainly a 40 S&W issue. If it really worries you, look for an aftermarket barrel that provides support. After starting with the G23, I felt I'd be better off with a G30, and have been very happy with it.

Well I have never had a problem, but there was alot of talk about this on the internet. But mostly about 2 years ago, I haven't heard of a problem lately. Like I said I only fire factory ammo no reloads. I will check the barrell. But let me get this straight if the brass hangs over the barrell this causes high pressure. If this is true why would Glock not fix the problem. I am not trying to discredit any sources, but you understand my position if this is a known problem why has it not been fixed. Anyone heard of this problem affected the G27? Thanks guys 0 -

I have thinned the herd lately, but still have 5 different Glocks...
19, 21, 23, 26, & 27. I have fired many thousands of rounds (including my own FMJ reloads) through these and the others I have owned in the past. I have never had any problems with any of them.
The main thing is I keep my Glocks clean and lubed properly. That is half the battle....

Thanks and thanks in advance for any other responses. 0 -
JB I took your advice and looked at both my HK and my Glocks and the G27 .40 round sits in the same place as the HK round. Only lip I see is where the feeder catches the brass. I compared them and measured them both with a micometer and they are the same. Could this have been an issue with older glocks or was it an issue with the ammunition? 0 -
The most likley cause of your "misfires" is the slide not being fully locked up- Take your glock, Make certain it's empty, very
slightly push the slide back about a 64th of an inch and pull the trigger. the firing pin will drop and push the slide forward
Being slightly out of battery the case head is unsuported and the possibilty of rupturing the case head exhists. When this happens nothing good comes of it. I'm aware of a number of incidents in the last six months or so involving glock 22's and 23's ( Erie Pa police and Erie County NY sheriffs). In the Erie Co. Sheriffs incident the ammo being used was Wolf 180 gr FMJ. Most of the cases I've heard about happen after a large number of rounds have been fired or with guns that haven't been propely cleaned leading me to believe that perhaps a build-up of fowling, bits of jacket and brass may be causing the slide not to fully close (as explained above)and by chance the round being fired has a weaker than normal case for some reason. Next time you have one of your misfires check to see if the firing pin strike is full centered or off to one side or another. If it is slighltly off center your gun probably wasn't fully closed0 -
"But let me get this straight if the brass hangs over the barrell this causes high pressure."
40S&W AMMO is loaded to around 40,000PSI which is high when compaired to somthing like the 45ACP at around 25,000PSI. Thats where the pressure comes from, not the pistol.
"JB I took your advice and looked at both my HK and my Glocks and the G27 .40 round sits in the same place as the HK round. Only lip I see is where the feeder catches the brass."
On the underside of the barrel, you see a rounded cut? It's there to guide the bullet nose into the chamber. That is also where the SIDE of the case is unsupported (the actual rim area of the case is designed to be unsupported, by thickining the metal of the case in this area), and prone to being blown out due to metal fatigue (due to repeated working) of the case. The cut is as large as it is to ensure reliable feeding in a combat situation, while the aftermarket barrels have smaller cutouts to help increase the life of the brass (targets don't shoot back while your clearing a jam).
You might want to cut a spent shell casing in half to see what is being talked about in the case construction.
