if the safety is on my gun, this means it has a round in the chamber, if the safety is off this means I have dropped the hammer on an empty chamber. Many of mine have the safety on and a round in the chamber, magazine in the box all the time, so by feel I know the status of the gun, all this safety on empty chamber is silly to me and I am not going to try and relearn something I have been doing by instinct for 30 or more years. If the trigger is back, safety on, there is a round in the chamber.
