First, let me state that I own a Glock and think that they're super reliable. However, at GlockTalk.com there's a thread where a fellow says he's shot a ton of rounds through his G-22 and only had two small parts break, an extractor and a trigger spring. His concern is what other parts may be prone to breakage so that he can anticipate their failure and be ready with a spare. Anyway, the point is that most of the people posting replies seem to indicate that nothing ever breaks on their Glocks and obviously they must not stock any spare OEM parts. Talk about denial!!! I have never owned anything mechanical that hasn't seen some breakage. Is there something seriously wrong with Glock owners.
