Answer:
As answered before, it all depends upon what state you live in.
Some states forbid the open carrying of firearms, other do not. In some states, concealing the firearm while in a car (on your person, or within the passanger compartment) is a crime, in others it's perfectly legal.
You'll hear people say that if you carry a firearm openly, you'll be hassled by the police. Again, in some states that's probably true. In others, not so much.
Best thing to do is educate yourself on local and state laws.
if you are concealing the weapon then it is illegal and also you have to have a handgun permit to carry a weapon, you have to gothrough the classes and training for this
It differs state to state. Check the local laws for your state, most places, to carry a gun, you need a concealed weapons permit.
The majority of the states have conceal/carry permits so check your state and see what you have to do to get one. Most of them make you take a class or training before they will issue a conceal carry permit.
Even if you have a permit, certain businesses and government offices will post a sign that weapons are not permitted on their premises.
Know what the local guidelines are and follow them. It's the only way to make conceal/carry work and be safe.
Different states, different things. While this might be ok in say Texas, I know for a fact that NJ will not tolerate it. You need to check with the state that you live in and with any other state that you might want to have the gun with you.
You lost me sorry, Check with your local law enforcement for more information
