I have needed my firearm twice in my lifetime. First time I was lucky enough for my training to kick in, presenting a very hard target prepared to fight for their life with good cover. I had my hand on the grip of my pistol but had not drawn. From my position he could not tell if I had a gun or not but I definitely had the tactical advantage,one if he did present his gun he was the one who probably was going to lose. The drive was watching the door of the Quiktrip. The thugs decided it would be in their best interest to leave, which they did, In a Hurry. The only thing going through my mind was ". Don't make me shoot, Don't make me shoot. A few seconds after they left I then started shaking, and could hardly stand up. Talking about an adrenaline dump.
Second time was two years ago in New Orleans. Both of my confrontations have happened at filling stations, Quiktrip & Circle K. There is a lesson to be learned here, be very careful when you are getting gas.
The only thing that stopped me from probably shooting the guy is that as I started to draw my gun, it was not there. I was half way out of the car, reaching for my gun , when I realized it was locked in a TSA approved case, because I was topping of the rental car on the way to the airport. This happened in broad daylight at 13:30. This 35 year old, very muscled thug, attacked a 65-70 year old man from behind only 20 feet away from the front of my car. The first punch was in the back right quadrant of the mans head, he fell forward landing on his forehead. I saw the thug, coming up behind the guy but didn't think much of it until he hit him. The thug was oblivious to my presence, am I starting out of the car when the "O Chit" moment happened. This thug then stomped the mans head twice. I was with my wife and she was truly in shock. As I am getting back into the car, locking doors,and starting the motor, I told her to call 911. She could not even hold on to the phone. We where in self protection mode, and tried to be the best witnesses possible. We got a good description and a license plate.
All I can say is, always be prepared mentally and physically. I feel very fortunate to have gotten through both of these unharmed. Either one could have turned fatal in the blink of an eye. I am sure the many hours continuing training courses above and beyond you basic CCW helped me to respond accordingly.
