My local gun shop where I spend at least 1 day a week never makes mention of condition 1. I sit and chat with them before and after range shoots but we talk about EVERYTHING except that...
If you had asked, my bet is that every single guy behind the counter at your local gun shop who is carrying a weapon...is carrying condition one.
The sooner you can get over the fact that you are carrying a perfectly safe weapon even with one in the chamber, then you can move on to what really matters...and that is when are you truly justified in using deadly force while carrying. You absolutely should be concentrating more on your local and state laws and how to legally employ deadly force when faced with a crisis situation.
