I am up to date on carrying my hand gun in Michigan. But this trip is taking me through a few of the larger cities up north and was wondering about taking some back up. Like my 12 gauge. I know Michigan is a "Duty to inform" and I have had the pleasure of informing a MSP officer I was carrying at a road side interaction. Can anyone point me in the direction of the laws on carrying long guns or shotguns in the car?
