The CM9 is my every day pocket carry for the past 5 years. I am on my feet most of the day and wear business casual pleated pants with a thick gun belt. Pocket carry has it's advantages: Good conceal-ability (no flashing), walking along with hand in pocket, no fallout when the pants are dropped in the rest room, shirttail can be tucked in. Element of surprise. My type of dress does not shout out concealed carry to any "bad guy". Always a pocket holster.
Too many things can go wrong when trying to rack the slide for an emergency first shot.
I chose the Kahr due to its size and double-action like trigger pull. I would not feel as comfortable with a Glock -like trigger. That is just me.
If you decide on pocket carry a D/A revolver could be a consideration.
