Re: A quick point-shooting question...
Instinctive shooting is done using hand/eye coordination. Sights are not involved. I found that for short range target engagements, my instinctive shooting skills were surprisingly good.
My technique was to extend my index finger alongside the firearm, parallel to the bore, and engage the trigger with my middle finger.
That way, I would point my index finger directly at the target, and most times, my POI would be within a couple of inches of my mind's-eye POA.
These days, I do not compete with handguns and do not own any. My HD strategy is deliberately impromptu, and involves shotguns.
If I ever need implement it, I would prefer to think, rather than react. I recognize that some time is lost, but I also intend what hesitation I have would be about employing lethal force, and never to have to hesitate to answer an accusation involving premeditation.
