I have a CPL here in MI and up until Jan. 01 2013 you could register rifles and shotguns of a certain length with folding stocks as a pistol and carry it "concealed" with your CPL.
Here in MI a long gun must be unloaded and encased or taken down and inaccessible to the driver and passengers. I put a folding Beryl stock on my .223 AK and can now get around that. It's now treated just like my M&P and I can carry it loaded in the passenger compartment of my vehicle (and anywhere else I am legal to carry).
I have been considering putting it in my car with a couple mags but I'm not sure the risk of theft is worth the small amount of advantage it may offer. I'm not sure if I like the idea of leaving a gun in the car unattended, even if it's hidden.
How may here have a carbine in their EDC?
I am not asking if you carry one for on duty purposes.
