By what you're stating I would not have pulled my weapon in this situation.
The way you described it he didn't appear to be a deadly threat nor did it seem that you were in danger of great bodily harm. You and your friends out numbered him and could have used nonlethal defense. Once you unholster your weapon you are using lethal force. You brandished your weapon so you broke the law.
Could he have had a weapon? Yes, but until you knew he had a weapon or you were in fear for your life you can not use lethal force to stop a threat.
"While in the back of the police vehicle the officer asked me why am I carrying such a large handgun and a spare mag. That it’s a CCW and your handgun isn’t supposed to be huge."
Is there a law in Ohio that says how big a CCW is supposed to be? Sounds more like he was trying to get you to talk enough to really nail you. NEVER talk to the police in this situation. Anything you say WILL be used against you in a court of law. You shut your mouth and talk to a lawyer.
You or a friend should have immediately been on the phone dialing 911.
They way it sounds to me you used poor judgment in this situation.
I'm not a lawyer so take it for what it's worth. For legal advise ask a lawyer.
