Pointing/shooting controls were all right, couldn't really complain about a mechanic that Nintendo's had since NES Duck Hunt.
You would have to make sure to always turn the safety of your shotgun before putting it away, otherwise if try to quick-draw you will shoot yourself in the foot.
edit: grammar
I imagine we might possibly come close by using a some sort of full body contraption that would somehow stimulate all your nerves. But it would need to be sophisticated enough to emulate muscle movement.
But then that's fundamentally incompatible with motion controls. So you'd have to then create something that's able to detect and interpret nerve signals from the brain to such a degree it wouldn't contradict the VR Headset and Haptic Pod version of the world. Otherwise immersion would tank.
