In D-9 my cv is at 400, but i usually shoot at 200 because I know usually it's a kill shot. D-9, the majority of my shot are snap shot, so i usually only have about .5-1 secs to fire before I gotta break it off. 38 I usually settle in and have more time to work on my positioning. I dunno maybe I'm just not use to the 38 yet.
