Can you carry a handgun in plain open sight in Missouri
It depends on where you are. In the U.S. each state sets its own rules. For instance, in Tennessee, there is no such thing as a weapons permit, it's a handgun carry permit, and applies to handguns only. Other than handguns, basically anyone can carry any legal weapon, but to carry a handgun, you must have the handgun permit. On the other hand, Florida issues a "concealed weapons permit" and it covers any legal weapon.
is it legal to carry a concealed weapon in Philly pa from northumberland county
With a permit, it is legal (lawful) to carry a concealed weapon. The legal system is complicated by the many disparate laws passed by various levels of government.
Depends on the laws of your state. In Virginia, open carry is legal- with or without a permit. In other states, a weapon may not be visible. You did not say what place.
No. As of 2010, Arizona allows anyone who can legally own a handgun to carry it, openly or concealed, without a permit. Before then, you could carry openly without a permit, but not concealed.
No it is not legal. NV only recognized permits from a few states, and CA is not one of them. For more information, see the associated link.
They are considered a concealed weapon, and are not legal to carry.
If you have a concealed carry permit, you do. If you don't have specifically a permit to carry concealed, then you can't carry a pistol concealed. Most states which have concealed carry legislation either prohibit open carry, or else have laws on the matter which tend to be a bit ambiguous. For example, it may be legal, but it may also be accompanied by "menace to the public detriment laws" which make it illegal once someone sees you carrying openly, feels uneasy about it, and calls the police.
I'm assuming you mean if you carry a weapon does it have to be concealed. It depends on where you are. For instance, the state of Tennessee does not issue a "concealed" permit, but a handgun carry permit and there is no specific requirement to conceal the gun by law. However, many states do require the weapon to be concealed. Check handgunlaw.us for more information.
It depends on what state. Each state sets its own requirements for weapons and weapons permits. For instance, Tennessee issues a "Handgun Carry Permit" which covers only handguns and does require concealment. In Tennessee, you can techically carry a concealed weapon other than a gun without a permit as long as said weapon is otherwise legal.
I wouldn't try that. Get a permit.
