I need to hear from those that have shot with both standard and big dot XS 24/7's. I need to know if the big dot has a noticeable advantage with speed in lining up the sights over the standard dot. If it doesn't then I need to get the standard dot as it will inherently be more accurate. I suspect most of the speed comes from the "dot the i" design, and maybe partly due to the size of the dot. (Over 3 dot design dot sizes) I have never actualy shot with the xs sights yet, but plan to use them for ccw.
