Some do and some don't. Like everything else you either agree or disagree. I'm comfortable carrying with a round in the chamber as I carry everyday at work or on my time. Very few times are my guns unloaded like climbing a tree stand or jumping out of airplanes with them. Never seen a ND when troops fell and dropped their weapon. AD's on the other hand do happen as they become careless in clearing the gun and are distracted/complacent. I also keep gasoline in my vehicles when not driving, LOL.
