I think what he is saying is that the striker fired is more of a safe action trigger/almost a double action trigger. It takes more pull than a single action. Making it safer to carry with the safety off. As far as C1 vs C3 (agree with phillip that the term does not necessarily fit here)...but from the aspect of carrying with one in the chamber or not (where only 1 action is needed to fire instead of 2-3 actions), my suggestion will always be C1, one in the chamber.
God gets blamed for a lot of things now days, they ask “why would He let this happen?, Why doesn’t He stop it? I really don’t know, but I wonder if He wants to ask us the same questions. All that is necessary for evil to triumph is for good men to do nothing
