Yes, it’s legal to carry concealed weapons in all Nevada casinos, which of course includes Las Vegas.
In fact, you may carry concealed anywhere in Nevada, except: public, meaning government, buildings (with posted prohibition signs and metal detectors); buildings at airports; and schools, including colleges and day-care facilities.
You can even drink alcohol while carrying: the blood-alcohol-content limit for carrying concealed in Nevada is 0.10 (.08 for DUI). Violation is a misdemeanor.
Signs posted on the doors of private businesses are not backed by the force of law. This means it’s not illegal to carry a concealed weapon into an establishment with a sign that prohibits it. It’s only requested, or strongly discouraged.
That said, if someone in authority in a place of business asks you to leave for any reason, which includes no reason, under the trespass law, you must get out. And this is the key point – if casino personnel discovers that you’re carrying a gun they have the right to ask you to vacate the premises and we assume that most would. If you’re asked to leave, you should do so to avoid being trespassed, which could escalate the situation to the point where Metro is called in.
Another concern might be if you attend an event, such as a concert, in a casino venue in which you'll pass through a metal detector on your way in. To enter a nightclub, as another example, you often run a gauntlet of beefy bouncers with metal-detecting wands or, in some cases, who pat you down. Since the security involved is specifically geared to preventing weapons from making it inside, in these cases, discretion is the better part of valor (in other words, either leave the gun at home or in the car, or don't try to go in).
Of course, the whole idea of concealed carry is that no one but you knows you’re armed, so even if you enter an establishment with signs prohibiting firearms, there wouldn’t, or at least shouldn’t, be any way they’d know you’re packing.
While we’re sure there are more, the only sign we can ever recall prohibiting entry with firearms has been at Sprouts, the poor-man’s Whole Foods, with one at the corner of W. Flamingo and Rainbow, the other on E. Tropicana at Pecos. (Buffalo Wild Wings has a no-gun policy at company-owned stores, but we don’t know if signs are posted at any of its three Las Vegas locations.)
All active and most retired law-enforcement and corrections officers can carry concealed in all 50 states.
For private citizens, Nevada has out-of-state carry-concealed-weapon (CCW) permit recognition with 16 states. You’re allowed to carry a concealed weapon in Nevada if you have a permit (in your possession at all times while carrying concealed) from: Alaska, Arizona, Arkansas, Kansas, Kentucky, Louisiana, Michigan, Missouri, Nebraska, New Mexico, North Carolina, Ohio, Tennessee, Rhode Island, South Carolina, and West Virginia.
