Typically speaking, and this varies by suppressor.
But typically, a shorter, thicker barrel will have less POI shift. Anything that has LESS barrel whip on firing.
Two barrels at 24"...one a sporter, one a heavy varmint...it's typical for the heavy contour to have less POI shift.
Two barrels with a heavy varmint contour...one at 26 and the other at 20...it's typical for the shorter to have less POI shift.
That shift isn't a big deal for most shooters, because there are very few reasons to ever shoot UNsuppressed ever again, once you have one.
