Believe it when I see it. And, in my experience, that article is rubbish. The M9 is not the ideal combat sidearm, certainly, but it is accurate, and I have seen HUNDREDS function just fine. My (based on long experience) guess is that the folks complaining the most didn't like the pistol before they ever saw one, and just project all their pre-decided faults onto the platform without ever giving it a proper chance. I (almost) hate to say it, but there are a good number of folks who will never be happy with the "perfect" 9mm - they'd much rather have a deeply flawed (in any platform) pistol in a "real man's" caliber... As has often been said (and might need to be added to the Annoying Phrases thread, if it isn't already there) - you can't fix stupid. And prejudice based on heresay and gunshop lore that is never tested in the real world is just stupid.
(All that said, I'd have rather carried a Glock 17/19 or Sig P226/8/9 while I was "over there" with .mil. Not that the M9 is the worst pistol for the job, it just isn't the best).
