In most cases I've heard, the so-called kabooms were not caused by the ammo. The cause of the KB was a dirty striker channel or weapon. This can happen in all semi-autos. The cause is this; when the weapon is fired some dirt or pieces of brass trap the striker/firing pin in a partially extended position. The slide cycles and picks up another round out of the magazine. The round slide up over the striker and under the extractor. As the round goes into the chamber and starts to encounter resistance, the striker/firing pin indents the primer and fires the round. The round is not fully chambered so the brass is not supported usually causing case failure and sometimes parts go flying. I've had it happen on a para-ordnance, so it's not just glocks.

I wonder how often Glock owners clean the striker channel... or if they do, over oil it to help collect gunk.
So... guys... what think? (fwiw, I don't really have an allegiance to any particular brand, I shoot Glock in competition, I carry SIG.)
That probably means they pulled the trigger, so a stuck striker was not the problem.
Any oil in the striker channel is over oiled. The striker channel in a Glock has a plastic (nylon, I think) liner and is self lubricated. Best way to clean it is a spray can of gun scrubber or similar after removing the striker (Q-tips or other such things will drive dirt into the front of the channel and will not remove it), but it doesn't need cleaning very often. You an generally tell if the channel is dirty by shaking the gun back and forth with the trigger pulled: The striker will make noise as it slides back and forth (except, possibly, on a new or very rarely fired gun). You can also look to see if the striker slides freely by taking the slide off, depressing the firing pin safety and turning it upside down and back to see if the firing pin slides freely through the pin hole in the breech face.
