| I have owned two glocks over a period of say 10 years, as duty weapons. I have worked with hundreds of armed professionals (LEO's, Military Contractors, Private Contractors, SF's, etc.) who have carried Glocks and prob put an "above average" amount of ammo down the pipe. Not a one has ever told of a KB with any caliber of Glock. I have had conversations with some LE Agency Firearms training staff who stated that they had, on rare occasion, seen this happen and was attributed to the glock firing out of battery, not to unsupported chamber design. None of these incident rsulted in a damaged gun. In fact, the only time I have even seen what was purported to be a KB from unsupported chamber in this forum, was a non-LEO or military incident where substandard ammo (import or reloaded). I am in the camp that believes that there are freak occurrences where a variety of firearms have fired out of battery, I was in a tactical pistol course when a good friend loaded a .40 into a 1911 mag (another story there) and actually discharged. Made a horrible cracking sound in his gun (a Korean or Vietnam era gun heirloomed to him by his uncle-all steel commander). I would call this a completely unsupported chamber as the case ripped down its length to expand inside the .45 acp chamber, inspection later showed no damage to the gun, which was used for a few more hours same day. Am I correct in my assumption that the KB cases seen around the forum are more likely caused by defective cases or improperly loaded ammo? It just seems that people that train and shoot often, using quality ammo, are not the people we tend to hear about KB's from (and by this I mean people that will actually put at least 500 rounds a month down the pipe). |
| In full disclosure, people who work with firearms on a daily basis are the ones who tend to become complacent, so haha. ok, now back to the issue, I can't find any incidents of a Glock duty weapon KB....can you? This leads me to believe that people that don't care what kind of ammo goes in the tube, seem to have attract this kind of problem..... |
I am the proud owner of a G23 .40 S&W and I have heard the early 40's had little chamber support and this combined with people's shitty reloads I believe would easily equal a KB. Glock supposedly added more chamber support but I can't find any definate dates on this, I do plan to be cautious and reload myself but believe most of it to be pumped up internet hype.

"Am I correct in my assumption that the KB cases seen around the forum are more likely caused by defective cases or improperly loaded ammo?"
––posted by the OP. Yes, I believe the vast majority to be attributed to this. ETA: And yes, Glock did redesign the chamber in their .40 pistols, some years ago. |

well then, piss off to all the anti-glockites, unless they can provide some sort of definitive proof that the design is defective (and I'm a Sig guy....) Exactly. If they were such horrible guns, they wouldn't be in such widespread use, simple as that. Seems Glocks are only "bad" guns on the internet. 
Thank you, "Sig guy"! 
It's simple scientific fact, and it gets so old seeing all the bullshit hype bandied about back and forth. Some folks are genuinely uneducated, and come on internet forums in search of knowledge. To see bullshit given to them in place of factual information is a damn shame. |

IMO, the Glock KB thing has been greatly exaggerated on the internet(errornet), as have a great many other things that I won't go into here.
I have owned 7 Glocks(only have 2 at the moment), have fired a combined total of more than 150,000+ rounds of ammo through them including my reloads, and seen countless thousands more fired from various other Glock pistols over the years. Guess what? I have never had a KB with a Glock, I haven't seen a KB in a Glock, nor have I even met anyone personally who has had a KB in a Glock, and some of the guys I know shoot much more than I do. I've never even seen a KB'ed Glock in person. I've only ever seen pictures on the internet. Most of them seem to have been with crappy ammo(go figure), although I have seen a few reported incidents with decent name brand factory ammo, but those are rare. I also have noticed that none of the shooters have ever had any serious injuries, which IMO is a testament to the safety and strength of the basic design. Now I admit that my experience is limited to maybe a few dozen pistols, owned by myself, family, and friends/coworkers, over about the last 15-20 years, and I admit that KB's do happen. However, I have seen other guns KB, so it is definitly not something inherent to Glocks. I usually don't participate in these Glock KB discussions, as they typically devolve into name calling and other childish behavior. However, I decided to just post my personal observations, take it for what its worth, but I know my experiences can't be unique. |

I believed the same thing until my G30 (which I carried as my backup on duty) KB'd during practice. What did they attribute it to if you do not mind me asking? Me wanna know too. The specifics, ammo, condition of weapon, etc. Also, what do you think happened to your G30? |

improperly loaded ammo
Yep, & would have KB'd any gun. Happens so little on Glocks it gets amplified. Tell you what. I bought my 1st gun & my 1st carry gun a G27 based off all the good things about glocks I read & seen. I have no concern carrying chambered or fear it will KB or "just go off" I now have a G17 added to my stock as well. |

Me wanna know too. The specifics, ammo, condition of weapon, etc. Also, what do you think happened to your G30? I was shooting factory Remington UMC ammo in the green and white box from Walmart. The G30 was about a year old (bought it new), and it had about 500 rounds through it. The bullet was not grossly set back in the case or else I would have noticed it when i loaded the mag. I don't believe the round was over pressured either since the ruptured case did not show over pressure signs. The case wall thickness did not measure any thinner than any other spent round, but I don't know if that means anything since I did not measure the case wall thickness before the kaboom. I believe that the case ruptured due to a perfect storm of the bullet set furthest back, charged with the max amount of powder, and with the thinnest case wall allowed by the spec. You end up with a round that is technically still in spec, but stacking tolerances can allow the case to rupture when fired through an unsupported chamber. The KB blew the mag out the bottom of the gun and broke the mag catch. It also burnt my hand pretty good. Glock replaced the broken parts, but they would not comment on the cause of the KB.
