Fundamentals of shooting a handgun

I made this as simple as possible, in my classes I do a more in depth explanation of each point.

-Apply the correct grip and grip pressure, support-hand hard, strong-hand firm.
-Apply the concept “prep-look-shoot”.
-Target focused by looking at a small spot.
-Blurry sights perfectly lined up.
-Not moving the gun when breaking the shot.
-Relaxed stance as explained in class, shoulders down, head back, arms bent, wide stance with left foot slightly forward(right handed shooters).

Do not over complicate things, if you are not hitting the target where you want to, you are not applying above mentioned correctly.
