Another thing people need to think about when shooting is their habits while shooting. When you are stressed you will shoot from instinct and muscle memory. I read a story about a DPS officer who reloaded his own ammo. While practicing he would pick up casings after each clip so he could reload them later. Some time later he got in a shootout during a traffic stop. He emtied his weapon and started picking up the brass. He was killed. I find it hard to believe but we are creatures of habit. Practice reloading. Shoot from odd positions. Train as if you are in a shootout if possible. Technique is one less thing you will have to think about becuase it is instinct and that might save your life one day.
