Climber, you bring up very good points. For CCW holders, each of us are certainly different in our abilities and approaches that is for sure. This is one reason I am very much in favor of extensive training and demonstration of competency as a condition of issuance. I flatly disagree with the approaches other states take with easy issuance with little or no training. I don't think it is in the best interest of the safety of society to do so.
In our case, the 16 hour training course we took was very detailed and serious. Great importance was given to de-escalation of threats and escaping if at all possible. The point was made over and over again that the use of deadly force was only justified if there was no other choice to defend one's life. The DA (one of the instructors) and the County Sheriff seriously emphasized the moral responsibility of choosing to carry weapons and indicated that if we were not willing to take a life, to exit the course. Some did right there. The 45 minute 1-on-1 interview I had with a Deputy was also very focused and intense. If he had sensed that I was not suitable as a CCW candidate he could have recommended a denial.
Honestly, it took maybe six months before I was comfortable in carrying a weapon, I had to completely reorganize my thoughts on this. Another thing is that since I am adamant on gun safety (all of the rules all of the time), I would have to violate these to defend myself with a firearm. It took a while to wrap my head around this and I still struggle with this to some extent.
It is not an easy choice to hold a license and carry. Lots of gravity here and it is not for everyone. In reality, I seldom carry but am eternally grateful that I have the option to do so if I wish.
