Honestly something all of us would love to see in call of the wild is a .410 shotgun. Single or pump. I think that it would be a great addition to the game considering we already have the ammo. I think that the .410 birdshot would be used a lot more than it is right now. It would be a great duck gun especially also for quail. It could be lighter than most of the shotguns already in game. But heavier than majority of the pistols. I hope you take my thought into consideration.
Wish you the best
