I have been shooting for 40+ years and never at more then paper or Deer. The one and only time I pointed a gun at another human being I was thinking "I wonder what vomit will do to the finish". I have trained with the local police but NOTHING gets the ordinary guy ready for that day. I am glad you came out okay. I didn't have to shoot the guy(thank GOD) he ran off screaming something about OH S*@t. But I was done for the day.
Please don't start with the if you draw your weapon you better be ready to use it. I was but when I saw his back the threat was over.
