I carry concealed whenever I legally can -- usually on my trips to Arizona or Nevada.
I wear a cover garment open in front. I start my draw stroke with my dominant hand near my belt buckle and sweep the cover garment out of the way as I move it to grasp the gun (worn in a strong side holster).
I'm a strong believer in the proposition that I need to be able to deploy my gun with one hand. I won't count on having the use of both hands in an emergency.
"It is long been a principle of ours that one is no more armed because he has possession of a firearm than he is a musician because he owns a piano. There is no point in having a gun if you are not capable of using it skillfully." -- Jeff Cooper
