A friend of mine was cleaning her S&W M&P 40cal the other night and said she took out the magazine, racked the slide back and forth about 3-4 times, holding the gun sideways (stove pipe clear way) and let the slide go forward and pulled the trigger and the gun went off inside her house. One thing I do not agree with that we were shown in the PD academy was take the mag out, pull slide back, close slide with release and pull the trigger so its not cocked. I kind of understand it but I'm wondering if she didn't revert back to training and pulled the trigger or if it was to take the slide off. Now, my question is, if she really did turn the gun to the side with the ejection port facing the ground and racked the slide 3-4 times how in the world didn't the live round come out? She had a lot of misfires at the range during qualifications with that same gun and factory Winchester ammo so could it be a faulty gun?
