97B.045 TRANSPORTATION OF FIREARMS.
Subdivision 1.Restrictions.A person may not transport a firearm in a motor vehicle unless the firearm is:
(1) unloaded and in a gun case expressly made to contain a firearm, and the case fully encloses the firearm by being zipped, snapped, buckled, tied, or otherwise fastened, and without any portion of the firearm exposed;
So what about re-purposed alternate cases?
When my wife was going to bring the S&W home from her dads, she (innocently) asked about sticking it in one of her bags (to which I told her how bad an idea that was). But what about a bag you use as a range bag that wasn't sold for such a purpose? Would you need individual cases within it to remain legal?
I remember seeing an old timers range box that was a wooden tool box that had a tray inside it that held his pistols. Since the tray wasn't attached, the toolbox could be presented as something other than "expressly made" for the task, even though it was outfitted very specifically to carry a dozen guns - very efficiently, at that.
Given the criteria of the statute is quite explicit, the intent of the first directive of (1) is a little vague. How does one prove express manufacture for the task? Pelican cases are used for guns all the time, but they're certainly not made explicitly for that (some models are marketed as such, but there's nothing that makes them not worthy as storage for something else).
