I’ve noticed when standing on a ledge with a pistol equipt, pressing the Crouch button will adjust your accuracy slightly depending on which pistol you are using, as most do when just crouching normally. It definitely improves accuracy at med-longer ranges particularly with the Krugermeier and ICA19 varients.
Attempting headshots at this stance seems to be easier than if not on a ledge. Particularly when manually aiming; it seems like the crosshairs have a larger radius (though not visible). I often am able to pull off headshots on ledges like this while my reticle is just BARELY over the target’s scalp.
Speaking of the ICA19s, on xbox Im pretty sure the Silverballer Mk2 varient’s “steady aim” perk lasts slightly longer than the Mk 1. I can only assume though being on Xbox One n having to use triggers… But it seems the mk1 is slightly more accurate at further distances. Again, if correct its only slight.
