    quote:Do kB!s occur in other guns or just in Glocks?
    kB!s do, of course, occur in other guns, but no one appears to be keeping accurate statistics for most of them. Many 1911-style handguns have partially unsupported case mouths, and numerous case separations have occurred in these guns. Early .38 Super barrels were particularly susceptible, and the critical observer may have noticed the predilection among USPSA .38 Super competitors for full beards in an attempt to cloak the vestiages of what came to be known as "super face."

    Respected firearms author Frank James, in 1994, documented a number of kB!s in HK USP .40 pistols, which do have fully supported chambers. (Also see this!)
    What is the relationship between reloads and kB!s?
    Most kB!s occur with commercially remanufactured or personally reloaded ammunition.

    Successive re-sizing and firing of a case result in eventual weakening of the brass, increasing the probability of case failure. The partially unsupported chamber in the Glock exacerbates this problem.

    "Hard crimping" or overseating of bullets, particularly in the .40 S&W, can cause dramatic increases in pressure almost to the same degree as a propellant overcharge. [See Annotation #3] Either alone or in combination with a weakened case, these factors can result in a kB!

    Some people have also postulated a relationship between the use of cast lead bullets and kB!, arguing that buildup of lead in the chamber can lead to pressure buildups as well. The jury seems to be out on this one as a direct causation, but lead build-up will sometimes cause a round to not fully chamber, and as Glocks can discharge with the action not completely locked up ("out of battery," [see Annotation #4]), this can lead to a catastrophic failure.


    that one story has been the grandfather of many stories on the Internet{it's old news been out for years}, but don't forget to look at these as well

    quote:...all with reloaded or remanufactured rounds by most accounts

    quote:What can I do to prevent a kB!

    ... Shoot only new factory ammunition out of your Glock. This is what Glock, Inc. recommends, as do several members of Glock-L. Shooting reloads voids your factory warranty.well, duh! it's not the gun. follow the directions and you don't get a kaboom.

    KB's happen in all kinds of guns. Rarely is it the fault of the gun, but usually ammo.

    I have seen many types of guns destroyed by double loads, obstructed barrels etc.

    same here, but common sense doesn't feed the bashers, you see that same article has been passed around the net so many times it not funny

    i bet if you sent that one article out once a month for a year, every glock basher would tell stories how they know that 12 glocks kb'd last year
