I can see the point of the OP but guns are not game controllers. Big hands, small hands, long fingers and short. Guns are more like gloves, one size does not fit all and there is nothing you can do to fix a poor fit. And fit/feel doesn't get into pointability which even for those that use sights exclusively makes a difference IMO.
Overall if you start with a gun that fits and feels well you are light years ahead of the game.
