Mr. Murphy’s out there, somewhere, waiting to ruin your day. How badly your day degrades depends on a lot of factors, but especially when a gun, ammo or let’s face it you malf and what you do afterwards. I had a Smith & Wesson 686 lock fail in the middle of a filming a TTAG video and didn’t seat a mag properly in the midst of a training exercise for my SIG SAEUR Active Shooter Training Instructor Course. And the usual failure-to-feed and failures-to-eject issues during gun tests. So no biggies. What’s the worst malfunction you’ve seen and how did it end?
