I referred to the grip's length. Any interest in a smaller gun is for both barrel length and grip length, i.e concealment in general.
Using your carry gun at the range sounds like a good idea, but that heavy trigger double action will not be your first choice, if actually competing. When scored by proximity to the bullseye, not loose patterns off at 11 o'clock or some such, you get real interested in what gives the best results. A carry gun needs to hit a pie plate. A target gun needs to hit a quarter. Kahr is a carry gun right from the drawing board.
