A loaded chamber indicator can break and indicate an empty chamber when the chamber actually still has a round in it. As far as I know it can't break and show the chamber full when it is actually empty. And therein lies the difference. Correct me if I'm wrong. EDIT: Also, never said I wasn't positively aware of the loaded state of my gun at time of loading. Said I didn't feel the need to do press checks to verify after the fact.
