Former JSOC dude here. Circumstances requiring engaging with pistols == bad day for everyone, so only a few things matter. Front sight focus (which implies maintaining equidistance from the rear sight posts), both eyes open, fast presentation, parallel grip, smooth trigger pull, reacquire, repeat as necessary. And optical sights = more things that can break / run out of batteries / fall off and make noise / etc etc.
