My friend and I went out today for some good old plinking. Among several other guns, we had our 27's and his old 23. Anyway, he had a catastrophic case failure that separated the entire rear of the case (we pulled the forward part of the case out with a pair of pliars) and blew his extractor out in a few pieces. Surprisingly enough the mag remained in the gun. No one was hurt but his glock is down for the count. I have only seen one other case failure (actually on that same gun) and it did the classic fill your face with unburied powder and blow the mag out. We have traced the problem to some old (a few years old...not really old) ammo that seems to be the culprit. I advised him to call glock and see what they wanted to do about it. I have heard that they are top notch to deal with. It didn't appear that anything else was damaged on the gun but I figured rather than just replacing the extractor, he should have a gunsmith take a look at it just to CYA. I figured glock was the place to go. Any other recommendations or advise. Sorry I didn't get any pictures...rookie move. Wanna kill these ads? We can help!
