I actually had been approved as a concealed carry instructor. I'd sat through classes for Utah, Florida, and Illinois ccw permits and had all three. I have had many successful years as a public school teacher, private industry learning consultant, and yes, even as a Sunday school teacher. Listening to questions and comments made in ccw classes made me rethink my future as an instructor enough to shred my certificate. Way too many wannabe warriors, people with a retribution wish, and those so full of old timey b.s. that I decided to enjoy my retirement without going back to handling a bunch of high school jock types. They are in the minority, true, but I didn't need that or all the implied liability that Illinois puts on the intructor.
All that said, your seed took root. I carry. Not always on my person but always in my vehicles and always have something close to hand at home or down at "The Hill".
What the carry gun is has no bearing on my willingness to draw it. Drawing, or pulling, or whatever it is called is my last chance thing. I avoid places and situations that would put me and mine in jeopardy as much as possible. I would never "pull" my gun as a deterrent unless in absolute certainty of serious harm. I don't talk about carrying or advertise it in any way.
I've been reading Ayoob's monthly articles on actual shootings for over thirty a five years and hope to never have to experience the aftermath of a shooting. Don't want the "mark of Cain".
Three things have stuck in my mind from the many classes, refreshes and seminars I've attended.
1. If you have to use your gun and shoot ..... It will be the most expensive shot you'll ever fire.
2. If you have to shoot in defense of yourself/others, you will be: arrested; and sued. It will likely be expensive win or lose in court.
3. Be sure you have a lot of insurance (or be so poor you have nothing to lose).
Probably more than you wanted in an answer but I couldn't do a simple yes or no. It is a deep subject with deeper moral implications. I will defend my life and that of my family.
