Some state's laws call the accidental revealing of your carry piece "brandishing." My state doesn't have that provision in our law. Brandishing would be considered waving your weapon around and acting as if you’re going to use it.
He didn't "Accidentally" show it. In this state, that would be considered brandishing.
That sucks. We're lucky to have one of the most liberal concealed carry laws in the country: No course or qualification if you're a veteran, just provide your DD-214. $50 for the initial application and background check, permit good for 5 years, $25 to renew it, carrying in a posted business is just a misdemeanor trespassing charge if you refuse to leave, no rules against "printing" or accidentally revealing your weapon, or even revealing it on purpose. I can even carry concealed in a bar, as long as I'm not drinking anything alcoholic.
The only thing I can't do is carry inside a courthouse, police station, on the grounds of a public school, or in a nut house. We also have open carry too but the federal gun-free school zone laws apply, so you can't carry open within 1,000 feet of a public school. You can carry concealed within 1,000 feet of a public school, but not on the property. Otherwise you have to unload the weapon and put it in the trunk. The laws also did away with having to store a long gun in a case, so now you can just put them in the trunk. Unloaded of course.
I lived in Texas for 25 years and they have no restrictions on long guns. In other words, you can carry a loaded rifle or shotgun anywhere in your vehicle. The police tend to frown on that and rather you kept it out of sight.
