Heres some info on NV.
NV has constututional open carry
Issues CCW with minimal effort. Take an approved class and ALL the instructors are on the Metro website with contact info. The shooting qual can be done with any caliber pistol, including 22. Their CCW is valid for all handguns owned. Unlike HI, you have to find out who's approved and qual with the specific gun.
NV law doesn't allow guns on school property without permission. So even if federally, you can CCW with a NV CCW at UNLV, you must get permission from them.
NV has no mag limits
Any gun transfers/sales must go thru a FFL, except if to family.
NV doesn't do any type of mental health check, which is 1 reason why WA has no reciprocity with them. WA requires some kind of mental health check.
Why this matters, Biden shortly after the shooting and others made a statement to ban "assault weapons", even though a handgun was used. And if any of the victims were armed, maybe they could have survived, but instead others had to wait for the cops to show up. Luckily, this situation sounded like he had specific targets in mind and not just kill anyone he sees. This is a guess since only 3 were killed and 1 injured at a college campus. And if it's anything like UH, there's way more people than that around.
