My three Banish suppressors had 1"-3" POI shifts at 100 yds. All of them were pretty much straight down which is aligned with the theory that the added weight is bending the barrels downward.
To actually calculate this exactly is a nightmare math problem, but one can get a relative ("first order of magnitude") understanding by just knowing the relative barrel size and weight differences. For example, if a 16" pencil barrel is half the weight of a 16" bull barrel, as a first approximation you can expect that the same weight suppressor would cause a POI shift on the pencil barrel roughly twice as far as the same suppressor on the bull barrel. This is NOT exact and only a "first order" approximation.
