Many years ago, I remember taking a Mauser bolt-action rifle I had into a city gun-shop for some work. I had it in a bag, with the bolt seperate, and (of course) no ammo.Seth wrote:Handgun or rifle.
If it was a handgun, "wielding" or "brandishing" would be having it in your hand and not in a holster. For a rifle or shotgun, it would be carrying it in a fashion that leads others to (reasonably) believe you might use it. Acceptable carry would be on a sling, in a case, with the action open (shotgun) or the magazine well empty and action locked open. Any time that the muzzle of the firearm "covers" or threatens to cover a human being, that can be both "brandishing" or "menacing."
Your demeanor and obedience to police instructions would also be important, and refusing to surrender a firearm when commanded by the police will do the trick.
It's a somewhat flexible definition precisely because it's difficult to analyze without reference to the exact totality of the circumstances.
I was stopped by a police patrol (it was pretty obvious what was in the bag). I showed them the rifle, with bolt removed. They were happy with that, and we moved on.
