Have and do shoot +p here. No problems. As long as hand loads are recipied and built right, headspaced, etc., there should be no problems.

ps-I've read the Glockkb faq on gunzone as well prior to buying my first handgun. After enough poking around, I came to the conclusion that for one reason or another any gun can kb made by *any* manufacturor. Struck me more as anti-Gl*ck crowd scare tactics after a while. I've still yet to talk to *one* shooter or see *one* incident of a kb on a Glock of any model.

From Wilkipedia:

"Coined by firearms reporter Dean Speir, a kB! (or kaBoom!) is the term used to describe the explosive malfunction of a firearm, with usually very costly, if not deadly, results. Glock pistol kB's usually damage the firearm, with minor injury to the shooter.

Controversy arose over Glock's safety standards when multiple cases of explosive malfunction occurred in Glock pistols sold to police departments in the United States. Upon pulling the trigger, the cartridge case would rupture and cause an explosion that would tear apart the gun and often send shrapnel into the shooter's face.

The cause of this malfunction was traced to issues with a purposely oversized (loose), and partially unsupported chamber in Glock's pistols chambered in .40 S&W, .45 ACP, .357 SIG, and 10mm. The chamber lacks full support in the rear by the feed ramp in order to facilitate feed reliability. The lack of support in the chamber, usually combined with lead bullets, reloaded, or +P (high pressure) ammunition, would cause the case to fail. The subsequent rapid expansion of gas into the chamber caused the pistols to fail, usually damaging the polymer frame and/or magazine.

Glock, in its own defense, says that in every manual that comes with their pistols there are instructions informing the shooter of the dangers of using non-factory rated ammunition, and that if the shooter uses factory loaded, jacketed ammuntion and makes sure to properly clean and care for their firearm, the firearm will function safely. Supporters also point out that kB!s occur in other firearms as well, particularly M1911 frame pistols. However, there continues to be controversy over the presence of an unsupported chamber, critics arguing that it is not necessary and is a liability for the company.

It has been purported that because of the the specific design of the polygonal rifling in the Glock, owners should not shoot non-jacketed lead ammunition in a Glock, since lead residue can quickly build up and cause a decreased bore diameter and therefore a dangerous over pressurization in the barrel and potentially create a structural failure or warping in the chamber of the barrel. You can notice a 'Bulge' in the fired case ejected from the Glock (even with Target loads)to see the result of the unsupported chamber.

Despite the controversy, Glock pistols still continue to be used by military and law enforcement agencies worldwide."

I forgot to mention that the handloads that were used when I saw the case ruptures were in fact lead 9mm.
I wouldnt call this a true kaboom. Only the case kaboomed. the pistol sustained no damage othe than the case not being extracted and the magazine being blackened

I saw this over at Mr. Completely's blog.

Thats a cool blog. Lots and lots of good links off of it. Thanks for posting that.

I've yet to see a Glock 17 in 9mm kB. However, the associated problem of *nosedive* jams [NOT *stovepipe* jams, usually caused by a limp hold on the gun] in the .40 S&W versions of the Glock have been so widespread that the Indiana State Police have discontinued their use of the >40 caliber Glocks, switching back to the 9mm Glock 17 and 19.

My suspicion: that this is in part a problem related to bullet shape and overall dimension of the loaded cartridge, plus some recent dimensional changes of internals by the manufacturer. I've traded my old Glock 17 to an unhappy sheriff's deputy who no longer has faith in his department-issued .40 Glock 22, and has the option to carry a personally-owned 9mm or .40 instead. And one of his fellow deputies similarly wishes to dump his .40 Glock, and I may pick it up and see if I can find out just what the problem...and maybe the resulting solution...is all about. But I think my first step will be a drop-in .357 SIG barrel.

I hope you read the discussions in the forums at Glock Talk as well.

I have two. One standard model 18 and one 18C compensated model. I want that 100rd mag, er 5 or 6 of them.

My limited experience [around 3000 rounds] suggests that the 18C is indeed the way to go. The custom tower for the Beta-C MP5 magazine is a preproduction item [or was] but sufficient nosing around at the subguns.com website will put you in touch with the developer.

I have little doubt in the ability of the Glock 18 to reliably chat away at full-tilt, but the drum magazine, which needs to be scrupulously lublicated with the graphite included with the drum in its ammo pouch, is probably the weak link of the system. Not to worry: the high capacity 33-round Glock 18 magazines are stone reliable, and reasonably cheap, in the $20-$30 range, now that the infringement of the high-cap magazine ban is hopefully forever in the past.
