1. Ohio gun laws are few and far between. There is state preemption, so there are effectively no local laws, beyond "discharging within city limits", etc. There are no licenses for mere possession or registration. We have a VERY pro-gun Democrat governor.
2. There is a 30 round magazine limit, although I've never heard of it being enforced since I moved here from Apartheid Chicago in 1986.
3. There is shall issue concealed carry.
4. Open carry is totally legal. There are a few cops who either don't know it or don't like it. They and their departments are looking at hefty judgements against them.
There are better places for gun owners than Ohio, but a HELL of a lot of worse ones.
