The gun laws in Nevada are extremely user-friendly.
There are no state permit, registration, or licensing requirements for buying, owning, or open-carrying rifles, shotguns, or handguns.
Here are the exceptions. A permit is required to carry a concealed handgun, and gun dealers run "instant" background checks on gun buyers through the Nevada Highway Patrol criminal database.
In Clark County (which includes Las Vegas), if you own handguns, you're required to register them, by bringing them (unloaded) to any police substation. There's no fee. You must carry the registration when you're transporting any handgun.
But that's about the extent of it. No background check is required on the private sale of handguns, even at gun shows. No state-government records of gun sales are kept; in fact, state law forbids it. There's no limit to the number of guns that can be purchased at one time. There's no waiting period. There are no state restrictions on the sale or possession of military-style automatic and semiautomatic so-called "assault" weapons. No safety locks are required. The list of non-restrictions goes on and on.
In addition, the concealed-carry (CCW) permit is "shall-issue," which means the permit must be given to anyone who can legally buy a handgun. The applicant must pass a training class (and, like everyone else, CCW permit holders are restricted from carrying firearms on school grounds).
The answer to your specific question, however, is no. No out-of-state concealed-carry permits are honored in Nevada; Nevada opted out of "reciprocity of CCW permits" in 2002, even though a Nevada CCW permit is honored by a couple dozen other states.
That said, since October 2001, Nevada has issued non-resident concealed-carry permits. Non-residents can apply for the non-resident permit the same way residents apply for theirs, by appearing at any country sheriff's office, then passing the Nevada CCW training course. The permit term is three years.
The two-gun limit on the Nevada CCW permit was lifted in 2002. Statewide, you can carry as many guns on a CCW permit as you own. However, in Clark County, CCW permit holders must qualify (by taking a CCW class) with every gun carried. The guns are shown on the permit by manufacturer, model, caliber, and serial number.
According to a statistically insignificant survey we took (we asked one security guard in a casino in downtown Reno), the casinos don't like patrons to carry guns inside their establishments, but there's not much they can do about concealed weapons, either permitted or not. (The whole idea of 'concealed carry' is that no one, not even police officers or security guards, knows you're armed until you present your weapon as the need arises.) Nevada casinos don't have metal detectors (one exception: You pass through a metal detector to get to the top of the Stratosphere Tower) and you're not frisked as you walk in, so anyone can be armed in a casino, and some customers undoubtedly are.
