As Sheriff Jim Wilson points out, personal defense is really about establishing a series of good habits that you regularly employ.
You are a self-described mediocre to so-so shooter when measured against the qualities and capabilities of the current group with whom you shoot. You know you have a lot of bad habits, but don’t know how to break them and create new ones more suitable to shooting accurately.
Developing good habits for defense in training is vital for the armed citizen. These habits might one day save your life.
