Week days I carry my .40 shield or my .38 model 640 no dash, as I can conceal those best while at the office. On the weekends, or on my day off, as I drive my wife or daughters to the store, I carry my 457 or 6904, as the cold weather allows me to conceal them with heavier coats. Also, if I had the 457 at the range that week, I will be more apt to carry it all weekend. Next week I may take the 6904 to the range, so I will carry that for running errands that weekend.
