While rare there are still 9mm Glock KBs. Like dennis has stated they are much more prevalent in the 40S&W versions though.
I want to go on record as saying that I personally like the Glock firearm. They function and their trigger reset is second to none. Accuracy is wonderful and they are pretty bullet proof, pun intended.
That being said, it is fool hearty to think "It can't happen to me" when dealing with this issue. It can. Here is all it takes to have a KB in a Glock, operator error. You are prone to it and so am I. We have to protect ourselves from ourselves most of the time, here is just another example. 9mm Glocks have blown up with factory ammo, so have 40S&W ones.
Factory ammo is just ammo that isn't made at your house. It can have mistakes made when loading it too. I got a box of WWB 9mm with a primer upside down, it happens. Can't there be an overcharged case in there too? Sure there can.
I had a KB in one of John Browning's best built firearms, the High Power. Granted it was in 40S&W and a .5gr overcharge, within the Lyman data though. What I am trying to say is, we know that unsupported chambers lead to possible problems, approach with care.
I recently got a new version of the Glock 22. This is what our local Sheriff's Department carries for a duty weapon. This one has the little stipples on it and the new frame notches, it is kind of cool. At any rate I only shoot reloads through it. I am a little gun shy, again pun intended, loading for this firearm BUT I approach it a completely different way than most firearms.
Case in point: I am currently working on a 180gr PHP load that I want to leave the barrel at 1000fps +/- 50fps. I don't buy factory ammo to carry and I think this is quite a formidable combination. When looking for a powder for this load I didn't choose the fastest burning one to get to that velocity. I don't want the pressure spike to happen all in the case, so to speak. So I went on a search for a powder that gives that velocity with a minimal amount of pressure.
The maximum pressure for the 40S&W is 35,000psi (from memory). You can get that pressure with W231/HP-38 and get near that velocity (again, from memory) or you can use SR4756 and get in the 28,000psi range. Better yet, if you use the minimum load of Longshot it gives higher velocity with even lower pressure. Now to me that seems like a win/win.
That is how we need to approach this issue, at least in my way of thinking. Don't stop loading for the firearm and call it bad or worthless or ........ You have a head on your shoulders that is supposed to have some gray matter in it, use it.
FWIW
