Catastrophic Failure of Semiautomatic Handguns
(For what it's worth.)
VERY important information regarding your auto loading pistols:
Catastrophic Failure of Semiautomatic Handguns
The following bulletin was received from the New Jersey State Police - Officer Safety Division
Date: February 23, 2007
Continuous reloading an chambering of the same round may cause catastrophic failure in semiautomatic handguns.
The Security Force at the Los Alamos National Laboratory in Los Alamos, New Mexico, recently reported on the catastrophic failure of a semiautomatic handgun when it was fired. The internal explosion caused the frame to break while the slide and barrel separated from the weapon and traveled down range. No one was injured in the incident. An investigation revealed that security personnel were repeatedly charging the same round of ammunition into the chamber.
Technical personnel at Glock Inc. advise that repeated chambering of the same round may cause the bullet to move deeper in the casing, further compacting the propellant. When a normal cartridge is fired, the firing pin hits the primer, igniting the propellant. When the propellant burns, the gas pressure drives the bullet out of the case and down the barrel. However, if the propellant has been compact, the pressure may increase beyond the gun's maximum specifications, causing the weapon to break apart.
Sigarms Inc's personnel confirm that reloading the same round five or six times will cause the problems, noting that reloading the same round even once will void their warranty.
Both manufacturers stress that the problem is not with the gun, but with chambering the same round repeatedly. The NJ Regional Operations Intelligence Center urges all law enforcement officers not to chamber the same round when loading their weapons.
***For example, when you clean your weapon, most of us drop the magazine and then pull the slide back thereby ejecting the round in the barrel.
After cleaning the weapon many of us will return the "same" round to the barrel that we initially extracted. Each time the slide slams forward on that same round it seats it deeper into the cartridge. Apparently, by seating the round deeper into the cartridge, it creates greater pressure when the round is intentionally detonated by a firing pin strike and is causing weapons to explode.

This should not be a problem with properly crimped rounds containing normal powder charges.
Several rounds, in fact, start out loaded with compressed charges.
Glocks are notorious for KaBooms.
They already blame reloaded ammo and lead bullets. Perhaps they are looking for yet another scapegoat.
I would be curious to know whether SIG meant reloaded, as in hand loaded, versus reloaded as in repeatedly rechambered.

Hell I may just go buy a new box for GP. Throw out the top round after I chamber it a couple times

Semi-autos have been around for many years. The Military for about 100 years, Police forces have used them for decades. A lot of them were "round in the chamber, take it out, put in it" years and it's a problem now?
Hmmmm. I wonder.

I regularly use the same rounds to load repeatedly, and I have been shooting handguns for over 30 years without a catastrophic failure. That includes some early, less than safe reloading experiments for a .44 Magnum that demonstrated the strength of a Ruger Super Blackhawk, and that God looks out after fools.
At the same time, I rarely keep a loaded mag more than three months, as I prefer to cycle my carry ammo periodically in practice and put fresh rounds in the mags. A box of carry ammo per year is not really that high a price to pay for that confidence.
Pocket lint, sweat, humidity, crud, weapons lube, etc. are not doing the ammo any good, and I really want the weapon to work as it should, when it should.
As the saying goes, there is nothing in the world louder than a click that should have been a boom or a boom that should have been a click.
In this case, I think someone has been overreacting.

I stopped reading this warning at this point. You get what you pay for...... for those of you that own glocks, good luck. 
IMO glocks are the worst mass produced handgun on the market today. This just adds to my opinion.

So, Jefe - glocks fall under 1911's in the TS foce continuum for handguns? Just checking, I've got my eye on a nice .40 that I saw at SHOT... (not Glock, not 1911 clone)

1911's are antiques, but I've never heard of one blowing up for the above stated reason......
I've rechambered the same round for months on end with no problems when fired. But then again I own H&K's. 
I did enjoy reading glocks excuses for failure.

Another reason for my not liking Glocks..... still love my 1911..... it may be an antique, but like me it does the job!

Absolutely. Not only is it not that expensive, I think its a great idea to fire a magazine of carry ammo now and then, as it shoots a bit differenly than the Winchester white box ball I normally use for practice.

Without knowing details, I bet it was a Glock in .40 cal. The chamber has had issues with the pressures of some .40 rounds. The only failures described that I have seen were in that caliber.
The HKs, paras, kimbers, sigs, etc have the supported chamber, factory glocks do not.

My .02c,
Back in the mid 90's I carried Hornady XTP 115gr 9mm in a BHP. After multiple chamberings, the bullet was definitely seated lower in the cartridge case. Whenever I noticed that happening, I just added the round to my weekly training ammo, and never had a problem.
Take Care...

You have got to be kidding me! Both of these manufacturers sell their firearms to Law Enforcement. Our agency purchased over 200 handguns from Glock. I can assure you that there were no instances in which they disclosed this defect. They must be the stupidest people on this earth if they are unaware that the loading of the same round is common practice in law enforcement!

Curious, did they check the ammo, such as was there a crimp? Same ammo? I have pulled a lot of bullets and I just can not see the action forcing the bullet to the rearward of the case especially if there was a crimp.
Keeping the old ammo, is as bad as when bullets would turn green in a LEO leathers.
