I haven't shot anyone, but I have had to draw on a fella....I was still in college, and I was at my self storage unit at 10pm that was rather unlit..well I was in the process of moving my electronics out (computer, stereo, ect.) when some dude came from around a corner to ask me for a light. I told him that I didn't smoke and he said "come one I know you have one......" and he started walking toward me in a hostile manner that if he kept on would have pinned me between my truck and the storage garage..I let him get within 25 feet of me and then I forcefully told him that I didn't have any matches or lighters and for him to stop were he was..however he just continued on so fearing for my welfare I drew my ruger p94 .40 S&W and he stoped dead in his tracks and says "wow man easy there, I mean you no harm" and starts backing up. I told him "I mean you no harm either but if you come any closer I will shoot you." He ran off after that....
I had my new truck....7 guns, a new computer, stereo, TV, VCR, DVD and other stuff right there for the taking. He could have killed me or put me in a comma if I hadn't chosen to react to a possible threat.
