Good morning y'all
Although Nevada does not recognize Arizona's CCW permits, I seem to recall an optional Nevada 'endorsement'/supplement to one's AZ CCW. I'll be traveling to Nevada in the near future, and although NV is an 'open carry' state, I'd just assume remain annonomous while carrying there.
I suggest you get a non-resident NV ccw license instead of open carry. But you can open carry at outside from the LV Strip, not in the Las Vegas Strip area. Nevada Concealed Carry Permit Information
