When I think shotgun use in Arizona, were I am at, I am referring to the use of buckshot for close range quick action, not because of state or municipal rules and laws. I doubt a pistol caliber in common calibers are to anemic for a 30-45lb coyote or smaller if used in close range-Which would be what pistol calibers are where designed for to begin with, not long range, thus why I said for close brush work. Not sure for some of you but I don't relegate myself to one gun or caliber for all things hunting. The pistol caliber carbine would be for use in addition to what I currently use ( .223, .243, shotgun w/ buckshot, even 357 mag revolver) depending on where and how I decide to hunt that day.
