I am often asked by beginning shooters what it takes to get into defensive shooting. Many, it seems, are under the impression that the techniques needed in a defensive situation are somehow more advanced and more complex than those typically needed for basic marksmanship.
In truth, these defensive shooting skills are not more difficult to learn. The same amount of time and energy is needed to set them into neural pathways. In fact, some of these skills are less complicated than those used in marksmanship shooting. Learning to use the sights on a gun is a relatively complicated skill. Kinesthetically orienting the gun toward the target is much more natural (you point at things every day) and, therefore, easier to learn.
