Is this a true statement? What is the science behind? Wish to get a good explanation about it.

I've heard it over the years .... "blah blah blah unsupported chambers... blah blah reloads...blah blah..."

None of mine have kb'd using factory ammo. So I'm not worried..

BS! You don't need to worry about that.
Unless you reload heavy or something like that most are caused by ammo other then Factory.

Take a look at this thread on Northwest Firearms post #2. 1911, AR, shotgun, Revolver, even the Walther P22.

Kabooms have been happening long before the .40 was even a twinkle in the 10mm loins.

Bad ammo, either factory or reloads, will make any firearm ka-boom.

For what it's worth, the 10mm Glocks have less supportive chambers than the .40's. .45 Glocks even worse. The 10mm brass bulges with barely anything above .40 cal level and I think most of the KB's are just because there are so many Glock .40's out there, and some ammo is out of spec and/or has be rechambered "hard" (dropping the slide on a round vs. "riding it home") so many times that bullet setback occurs, which drastically raises pressure.

I don't believe it's a problem using well made ammuniton. There is a lack of case support in the glock .40's, but it's OK as long as everything is "good". No overpressure ammo. No ammo that has been rechambered over and over again causing setback. Again, this is a concern with all ammo, but .40 is already on the ragged edge, so a little extra care wouldn't hurt. I have seen a couple of examples of a glock .40 going Kaboom, but in those insances I believe it was ammo related, not the fault of the gun itself.

Early Federal .40SW had thinner case walls, that's where most of the early KB problems came from. Federal later thickened their case walls and the problem went away.

Any KB stories you hear about these days are due to overpressure from defective ammo or reloads.

Any specs that we may use as reference in identifying good case/shells? e.g. thickness must be ___ mm

In addition, any max power on the rounds specs such as velocity or whatever?
