You just mentioned "Firm grasp, smooth trigger roll, and knowledge of point of aim/point of impact coordinates will allow you to surprise yourself with the grouping ability of many of the smaller carry guns."
I'm not sure I fully grasp the concept of a "smooth trigger roll".
Could you define how you understand it?
