Actually, if you even have to
present your weapon
without firing, you are in the "wrong place at the wrong time", unless of course you are at home.
So--do you stay home all the time? Avoid parking lots? Avoid ATMs? Avoid service stations?
....and since I don't carry a battle rifle and a bandoleer full of loaded magazines I feel no shame in retreat or hiding like a man who wants to get older should do.
Retreat, if safely possible, is of course one's duty in many jurisdictions, and it is arguably the best thing to do, tactically and legally, in all jurisdictions.
The problem arises when escape is not safely possible and deadly force becomes necessary as the last resort.
If you need more rounds than what you have in the magazine in your gun you might want to think about why you are in that place at that time and rethink your need to be there.
If you need to employ deadly force at all, you will not find rethinking your need to be where you are to be helpful at all.
I believe it is not unreasonable for one to expect to be attacked by two or possibly three violent criminal actors,if one is attacked at all. Statistics bear that out.
I do think it would be unreasonable to expect an attacker to not be moving very quickly, if deadly force is justified at all.
I do not think it is reasonable to expect to be able to shoot with any kind of precision in a defensive encounter. I can shoot pretty well at the range, but in defensive pistol training, I have found that getting all of one's shots onto a torso sized target at close range with great rapidity is by no means a sure thing. That is
without having my skills highly impaired by the stress of a real attack.
Looking at accounts of real world defensive encounters leads me to believe that it is likely to require two or more shots in the torso of an attacker to stop reliably.
That puts my personal minimum at ten or more rounds.
I now leave the five shot revolver I bought when I first started carrying at home most of the time. I have no interest in the small single-column pocket semi automatics.
