I read this on answers.com, its supposed to give general information about different pistol calibers. Just curious if its another tall tale found on the internet.

"The .40 S&W has been noted in a number of cartridge case failures, particularly in Glock pistols due to the relatively large area of unsupported case head in those barrels, given its high working pressure[8]. The feed ramp on the Glock .40 S&W pistols are larger than normal, which leaves the rear bottom of the case unsupported, and it is in this unsupported area that the cases fail. Most, but not all, of the failures have occurred with reloaded or remanufactured ammunition. Cartridges loaded at or above the SAAMI pressure, or slightly oversized cases which fire slightly out of battery are often considered to be the cause of these failures. These failures are referred to by many as "kaBooms" or "kB!" for short. While these case failures do not often injure the person holding the pistol, the venting of high pressure gas tends to eject the magazine out of the magazine well in a spectacular fashion, and usually destroys the pistol. In some cases, the barrel will also fail, blowing the top of the chamber off."

Yeah...those kB's have been all over the net. Especially posted by "Glock haters".
As long as you use factory, jacketed ammunition or jacketed handloads that are loaded to spec then you'll never have a Kaboom! in a Glock....period.
