I've been safely handling firearms since 1955. Last year, an LEO friend of mine and I were looking at some of my handguns. I was in the process of unloading one of them... gun pointed in a safe direction, finger off the trigger, dropped the magazine, went to rack the slide, and for whatever reason, lost control of the gun. It was a DA/SA striker-fired gun, so the short slide movement cocked it. I foolishly reacted by trying to catch the gun... instinct, I guess. I ended up with a 9mm entry and exit wound in my left hand, at point blank range. NO excuses, and yes, I learned from it, and yes, I was lucky. I post this only in the hope that it may save others from similar or worse injuries.
I have two pics of the results... Number 1 is a poor quality, cell phone pic at the hospital... number 2 was taken one month later.
I'll just post links to the pics as the first one is somewhat graphic
