I am a CCW holder in a state that does not require such a permit to carry (Arizona is "constitutional carry"). I have also been an NRA instructor as well as am currently a competitive practical shooter. I carry every day.
That being said, I also take time to practice my defense drills at least once a month (which is scary considering the police only qualify at best twice a year, sometimes only once...)
I agree with the poster above that practice is a key responsibility to carrying a weapon. However, it shouldn't turn people off to it.
If anyone is interested in learning about just how firearms work or what not, I would suggest seeing if there is a 'Pink Pistol' club in your area. I have taught classes with them before, and found that they are a fine group of people... and who knows, you might have fun doing it, and pick up a new hobby.
