John Correia at Active Self Protection, his YouTube channel, still says that no armed citizen reloads under fire. He says if YOU ever do that, you "will be the first armed citizen ever to have done so." He did a study of how many rounds were "needed" analyzing many years of thousands of videos including all the ones he watched for show prep but never included on his channel. He showed very few that needed six rounds, none more. It is not round count, but the first anatomically significant hits that matter. He shows one recently where a revolver guy "needed" all six rounds, but that is debateable.
If you are carrying a revolver, are you going to do what amounts to a "mag dump"? A cylinder dump? Or are you going to fire once and assess? Are you going to double tap and then assess? Is there any way to know what you are going to do when you are in the fight of your life, for your life?
I had to quit watching the "mag dump" videos on YT, because it is so disheartening. It does not instill confidence in LEO's, y'know? Most people will just thrust the weapon in the general direction of the threat and run the trigger until it occurs to them to stop.
This actually works to save lives!!!
It works so well so often, that I believe in tempering my comments on such subjects as caliber, especially.45ACP versus 9mm, spare mags, barrel length, carry position, etc., etc.
It works so well so often that you must understand that when you are practicing reloads, you are preparing for the worst-case scenario. Yes, if you are ready for the worse thing, a fortiori, you are ready for the better thing.
(Here is an anecdote, which does not prove anything but does illustrate my thinking

There were two officers pursuing a perp who wrecked his car and jumped out shooting. Happens a lot. Both cops jumped out and started shooting, emptying five 17 round magazines, between the two of them, at the man who emptied his pistol at them.
They were about a car length apart.
Nobody was hit.
He was arrested successfully and prosecuted successfully.
This is a total win in my book.
Please correct me. I write on the internet to give people an opportunity to contradict me. That is how I learn.
Kind Regards!
