+1 to Miller.
Note that a gun's handling is composed of weight, tetter-totter balance point, unmounted swing effort, and mounted swing effort. This set of numbers is to handling as a set of stock dimensions is to fit.
To know the influence of the barrel set you must know weight, balance point, and moment of inertia at balance point (center of gravity). MOI requires a more sophisticated measurement than weight and balance point. MOI is basically a measure of weight distribution. Note that the barrel length does not directly enter into the factors.
It is quite possible to have a short, heavy barrel with higher MOI than a long, light barrel. While barrel length is not a direct measure of the barrel's influence on swing effort, it is the most commonly considered measure.
It is quite possible to spec a gun for handling just as it is to spec fit.
