Although always enjoying the friendly banter between the metal and plastic gun crowds as well as the 9mm vs. 45 gangs, I've observed through the years that any mechanical device can fail for a variety of reasons. Over my time attending and participating in matches this has been confirmed by observation. There also seems to be a direct inverse relationship between malfunctions and home gunsmith tinkering but that's more anecdotal than quantitative on my part.
For those of you that remember Todd Green when he worked at the NRA and shot locally (and those that don't) - here's a good article he's written with his own observations from inside the industry. Enjoy.
