But what I pointed out was it isn't an instinctive manipulation.
What you're calling instinctive, is just a matter of what you have trained yourself to do. We call it instinctive when we have learned to do it below the level of conscious thought. It can even be a moderately complex task, using both feet and both hands in different ways at the same time. like driving a standard (stick) shift.
Instinctive actions can also be the wrong actions, IF you are using a system different from the one you practice with.
I had this lesson taught to me many decades ago, and it only cost a lost pheasant. Friend showed up at the farm, wanted to borrow a rifle, because he had seen a deer up the canyon, and only had his Browning Sweet 16 with birdshot. Asked me to go with him, and take his shotgun, in case we did flush some birds. For some reason I can no longer remember, I agreed.
No deer, but we did put up a pheasant. Three times, I punched the safety off, and pulled the trigger, without a shot firing as the bird flew off.
Would have had pheasant, if I had been carrying my Winchester. But, the Browning's safety was behind of the trigger, not in front, like my Winchester, and that's where my finger instinctively went, to the front of the trigger guard to push the safety off.
I tell this story often, mostly to the people who rotate the pistols they carry for self defense, using much different models with controls in different places, to illustrate that when carrying a gun you might need to use instinctively, carrying something you aren't really used to might not be a good idea.
