To get a NV ccw permit you have to.pass a 30 shot proficiency test.
21 states now have permit-less / Constitutional carry laws. If you are legally able to own a handgun, you are legally allowed to carry it.
That's fast approaching 1/2 the states in the US!!
Some states have restrictions, for example North Dakota. You must be a resident for a month before you're allowed to carry. Only concealed carry is allowed -- no open carry. Doesn't apply to non-residents.
Most of these states continue to honor CCW permits issued by other states with which they have a reciprocity agreement. Most also allow you to apply for a CCW permit if you want it to use the reciprocity feature in other states as you travel.
I've taken the 30-rd CCW live fire test in NV. If you fail that, you definitely are not to be trusted with a gun around other people! In the grand scheme, requiring a test begs two questions: (1) who decides on the standards to use -- could be too easy or could be too difficult to pass, and (2) name another Constitutionally protected right that you can only exercise if you pass a test. If you're lost on that last point, look up Voter Registration Literacy Tests.
Some states have issued carry permits to people in spite of the applicant being legally blind. Yet, we can't get a permit issued in Hawaii DUE TO blindness .... of the state to recognize a right as a right.
