Good work on maintaining control!
When I first bought my M&P I went shooting with some friends, one of whom brought his 92f. As he was coming back from the line I looked up to see talking to someone, finger on the trigger, gun pointed right at me. I wasn't too thrilled about this so I hopped out of the way real quick and asked him to be more careful, he replied that he had just finished shooting, and so it wasn't loaded.
I looked at it, and saw that the slide was closed and the hammer back. I asked him if he was sure, to which he replied, "positive, look." He pulled the slide back and out one last round he didn't realize was in it. He got a real befuddled look on his face, I got an unimpressed one. Fortunately no one got hurt, and he wised up after that and was being real careful to make sure to be safe.
I figured I was a careful guy before, now I'm down right anal retentive.
