Nevada is a "Shall-carry" state i.e the the authority that grants the licence has no discretion, i.e any numpty can get one.
There is no permit to purchase required
No requirement to register the gun(s)
You only need a concealed carry licence for a hand gun
Open carry is permitted
No assault weapon law
No restriction on the size of the magazine
It is not illegal to carry a gun into a casino, although the casino will probably ask you (nicely I'm guessing) to leave.
