You would be surprised. There is a sizable cadre of concealed carry practitioners who insist on carrying "condition 3," also known as "Israeli carry," which is a full magazine but an empty chamber.
And they are posthumously referred to as "idiots".
I know two people that do that, both with a M&P 2.0.
They insist that they can draw, rack and aim quicker than I can draw, unsafe, sight and shoot them between the eyes with my Condition 1 1911.They are wrong.
They are stupid.
