I did a search and didn't see any scenarios like this so let's see what you think.
I thought of this today while me and my wife were at the gas station. I was pumping gas while she went inside to grab some drinks. I started coming up with different scenarios in my head and thinking about how I would react, and this came to mind.
I'm pumping gas and I notice two guys go into the station while my wife is inside. They come out with weapons in hand and dragging my wife with them. They force her into the car and try to get away. She is not armed but you are; what do you do?
The first thoughts that came to mind were: shoot the tires, shoot the engine, shoot the driver.
Shoot the tires, you risk a nasty crash with your wife in the vehicle.
Shoot the engine, your edc may not be enough to do enough damage to effectively stop the vehicle (I carry .40 caliber hollow points).
Shoot the driver, again you risk a crash with your wife inside.
I realize the ideal situation would be to not let them get in the car or get a hold of your wife, or have your wife carrying also; but with the given circumstances how would you react?
Two armed guys, your wife is unarmed and in their car, they are trying to drive away; GO.
ETA: If you don't have a SO pretend its your friend, sister, brother, etc.... Also when I was thinking about this I have to take into account that my wife is pregnant so her ability to fight back isn't nearly as good as normal. Just something to add to the equation.
