Haha... Like I said, it is a bit embarrassing and I think I have told this story before, but here you go:
In my senior year in high-school, I spent a lot of time with my grandfather who owned a used Baretta 92F which was a Police model that had a cut down hammer (there was no hammer spur for your thumb to catch on). It had a decocker but I had never used one before. We had cleaned and reloaded the gun which of course ****** the hammer. I wanted to let it down, and being ignorant of how a decocker works, I instead did the old "pull the trigger and ease down the hammer" routine. You will remember I pointed out that this was a cut down hammer and you can guess where things went from there. I was sitting when I did this, and foolishly had the barrel pointed at my leg. Fortunately, we always load an FMJ as the first round, just in case there is an accidental discharge. The bullet passed right through the thickest part of my right thigh (thankfully missing the bone). The hole in was almost a perfect circle. The hole on the backside of my leg was a little more ragged and larger, but still, pretty small. When it happened, the shock was immediate. I said "@#$%, I shot myself", the only curse word I ever used in front of my grandparents.
There was no pain and initially there was very little blood. I set the gun down, stood up, stuck my thumb in the hole in the front of my leg and my ring finger in the hole in the back and made my way up to our house, about 200 yards away. I had no trouble walking, but started feeling light headed. My grandfather had run ahead of me to tell my mom and she came running out hysterical. I reassured her it was alright but that I was pretty sure I was going to pass out. I laid down on the floor and did. I came to about 1 minutes later as they were trying to drag me to a car and were bouncing my head off some brick steps. I told them to stop, got up and walked the rest of the way to the car... again, without problems.
On the way to the hospital, my leg started burning intensely and continued to do so for a while. When we got to the hospital, they took x-rays to ensure no fragments were left in me (it was a through and through...

) and then did exactly what you see in the movies. They put neosporin on the hole in the front followed by a small gauze pad and the same on the back and then a couple of wraps of gauze around my leg. That was it.
The next day my leg hurt like hell and I was on crutches for about two weeks after. I have no long-lasting impact from it (besides my wounded pride), but I do have two nice scars as a constant reminder to be exceedingly careful with firearms and to treat them with the utmost respect.
WIth that said, I want to be clear that I was insanely lucky. If that bullet had clipped a major blood vessel, I likely wouldn't be telling you this story. If it had hit bone, I might not be walking. However, it was a true through and through without hitting anything but meat and from a movie perspective, I was still completely mobile and functional immediately after it happened. More than anything, it made me rethink the idea of stopping power and shooting someone and then seeing how they are doing.... bullets aren't magic and you can shoot someone without it stopping their aggression, so best to keep shooting until they stop.
PS. Oh... and my high school buddies found it endlessly entertaining to mock me about it... here are couple of photos I kept from some of that razzing.
Sorry to hear it--but, uh, I think it's gotta be an interesting story, yes?
I'm truly surprised it could happen, unless it just went through fatty tissue. I hear so much about the tearing capacity of a round on flesh, and have fired at a roast to see what it does to muscle tissue for research purposes.... These days I think I also imagine the bad guys use hollow points which--well, you know. What kind of round did you fire? And--okay, what is the story?
I have used the "through and through" device myself in my writing, too often (probably why I'm so sensitive to it; it's such an easy way to force drama and brush off consequences). I just think, if you shoot 100 people through-and-through, 90+ of them are gonna be waiting for their internal and external stitches to heal. Am I totally off base?
