The corner shot can fire around corners.
Last time I checked, it was against a concealed permit to show your guns. That qualified as brandishing. Or so I've heard
Glad my laws pertaining to concealed carry in Ohio are a bit different. But, in Ohio we cannot carry concealed in any establishment which serves alcohol. But that is a discussion for another day. LOL.
Looking back over the last 20 years, I have never had any occasion where I have contemplated carrying openly. As a non drinker, I do not appreciate not being able to utilize my concealed permit in restaurants just because they serve alcohol. But while it leaves room for any number of debatable scenarios, I do respect the logic behind the law.
