I carry a pistol in my car. I had to pull one out and point it at someone once;
I was driving my Dad's car one day with my little brother, I was around 19 YO, he was probably 13. My dad always had a 44MAg under the seat, and I knew how to use it safely. We were stopped at a stoplight in a semi-rural area, behind one car. The light turned green and the car in front didn't move. I really wasn't paying attention, so I thought it may have been a short light and the guy didn't notice. The second time the light turned green, I tapped the horn. No reaction. I blew it a few times again. I figure this guy is asleep, but then the door opens and this guy stumbles out. He then reaches into the car and grabs a bat. Although pretty drunk, he was pretty big.
I don't know if it was the right reaction or not, but I fetched the gun, pointed it towards him and asked him if he would like to think this over (something to that effect). He didn't say a word, but turned around, got back in his car and pulled into a parking lot (presumably to sleep).
Now.....I often think of this situation and all the things that could have happened. If this guy advanced and started bashing the car, what would I have done? If he advanced to do bodily harm, what would I have done?
I really don't know; thats the problem with a 44. You just can't fire a shot in the leg to disable.
In any case, I am glad it worked out that way it did.
