You have to be willing to kill.
Agreed. My father who served in the United States Army pre-JW was the one who taught me firearm safety and use. He was a multiple decorated soldier who served in Korea during some of the bloodiest fighting. He was also a military trained sniper. I cannot count the times he drilled it into me that you NEVER draw a weapon unless you are willing to pull the trigger, and you NEVER pull the trigger unless you intend to kill what you are aiming at. Of course shooting range practice does not involve killing anything other than several hundred rounds of ammunition per year. But you are right, it takes a learned mind-set to actually be willing to use a firearm for self-defense, and not everyone is capable of that.
If you use a
gun its best to get the best defense ammo you can find.
Again, I agree. I use what I consider the best available hollow-point PDA I can find in my ACP carry mags. They will expand and fragment and not just go through and keep going to God only knows where.
Nothing beats being wise and avoiding situations and places that you really don't want to be in.
And that is why people should learn "Situational Awareness". It is said, "With great power, comes great responsibility"; and for anyone who chooses to carry a weapon of self defense they need to know they have great power (over life and death) and accept the great responsibility that attaches as a result. Do what must be done to avoid situations that will put them in the spot of making that choice, but be ready to make it and accept the consequences of their choice if they find themselves in a situation that demands action.
