Shotgun is much more simple.

Shooting is very simple, at those ranges you don't need any level of experience with a firearm to be effective. You just need to point the gun and fire.

And honestly, that those ranges, a shotgun doesn't have a huge spread either. If you can't hit them with a pistol at >21 you can't do it with a shotgun.
