Following pics show hits that are not in tight pretty little groups, but they would stop or kill most mortals.
At 15 feet or so, it's repeatable most every time. Just point-n-pull, point-n-pull as fast as you can point-n-pull.
No thinking, no cognitive directed sight alignment, MT stance or grip, etc., and shooting one handed. The sights will be in proper alignment and you will get a correct FSP everytime you point.
Want to check that out, put your index finger along side the frame, and then point - stop - look at the sights and the target.
You certainly can take the time to use the sights and confrm their correct placement on the target, unless it's sort of dark and/or you can't see or focus on them, which will be the case per the science and the data.
The bottom line is use what works for U.
