After 30+ years, I retired from the Army in 2012. I am still adjusting to living among civilians 24/7.
I often remind myself that most folks haven't been trained to kill. It only takes our military a few weeks to inculcate in our warriors the willingness to kill. Trained to kill, yes, but only while subject to strict authority. Most folks do not go through this.
Those of us who have chosen to carry a self-defense handgun must be ready, mentally, physically, and psychologically, to actually use it. This takes understanding and training. We should also be prepared to deal with the consequences.
LTC Dave Grossman (Ret) has written two books which deal with these subjects:
On Killing and
On Combat.

In 2015, John Daub, of KR Training
http://krtraining.com near Austin, used his handgun to defend himself and his family. Massad Ayoob interviewed John for "American Handgunner".

Just as we diligently train to use or self-defense tool, we should also train and prepare for the act and consequences of actually using that tool in defense of ourselves and/or others.
