Open carry is legal in Michigan, Yes, some officers love to harass individuals who OC, get on youtube and watch Kimberguy he has quite a few videos where he was harassed just because he was OCing. Some LEOs believe that just becasue your have a CPL, it means you give up your right to OC, which is NOT the case, it just means you have the option to CC or OC, both of which are legal, one with a permit, and OC w/o a CPL has restrictions, such as being in a vehicle w/o a CPL.
Either way, be careful, and be prepared to deal with BS from "frightened civilians" MY question is, when was the last time they seen a BG OC a pistol in a holster while eating some french fries? Just be polite if youre ever confronted by an LEO, cooperate, and if they hold you for a period of time [not the PD] make a complaint with the PD and the AG do not let it go unchecked. OC is a choice, its a right.
Michigan.gov has more info on OC and CC.
