So I have noticed whilst playing that a number of under barrel mods add to stability. Yet, I have found, so far, three different types of stability mod.
These are, Initial Bullet Stability, Horizontal Stability and Stability.
I think the names are quite self-explanatory, but how do these actually effect bullet spread? For example, I've had no issues with horizontal gun drift at all in the game, which makes the Horizontal Stability mods worth much less to me than the general stability mods.
So what do these actually do?
