First and foremost, it is imperative that you practice your proper fundamentals,
Sight picture,
Grip,
Stance,
until muscle memory kicks in.
In my experience those with good muscle memory fundamentals utilizing sight pictures, can, and do easily transfer that muscle memory to point shooting when in danger close.
Not so much the other way.
My advice would be learn to shoot using your sights, with proper grip, and proper stance. Shoot allot. It will become second nature to you.
To practice point shooting move your target to within 3 ft.
(WARNING - most ranges will not allow you to move targets closer then establish distances, and few will let you pull from a holstered condition)
Load 2 rounds, then pull your weapon (from a holstered position) and shoot both rounds, using your weapon as an extension of your hand, then re-holster.
Speed is not needed until you get proficient in the action. Do this until muscle memory keeps your groups together, then add 2 more bullets and continue. Then move the target 6-10 ft. etc...
You can also do this without drawing your weapon from a holstered condition by starting from a low ready position and bringing the weapon up to line of sight.
You can also practice at home USING AN EMPTY WEAPON from a holstered condition.
Spend time at the range, when and if you have to rely on it your muscle memory will takeover.
