Id look into the training doctrine of COL Rex Applegate.

I would advise
against "hip" shooting or the reflex/CQB methods.
Those are for advanced/highly trained armed professionals.
If you have a lethal force event you'd have to explain to a homicide detective or jury how you did not aim your weapon's sights at the subject, only using trick shooting.
