As a new gun owner (little over 1 year), for the first 6 months or so, I felt uncomfortable with leaving a round in the chamber at home (pistol sitting on the table in arms reach). But slowly I would leave a round for a few hours/days, then not. Then eventually just left a round in there. My thinking was that I wasn't "confident" in my equipment being so new. But I slowly gained confidence. What helped me was when I was in condition 1, the gun didn't go off at all while on the table.
So by the time I carried in Nevada, I had total confidence and was in condition 1 at all times. My wife still has to learn this confidence.
I read something also that helped. "Carrying without a round in the chamber is like trying to put your seat belt on right before an accident".
Active Self Protection on youtube has a few videos where racking the slide failed, which cost the victim their lives and others as well.
The only thing I don't keep in condition 1 is my gun AR and shotty, but both sit in the safe 99.99% of the time (leaving only the last Saturday of the month)
