NRS 202.350 Manufacture, importation, possession or use of dangerous weapon or silencer; carrying concealed weapon without permit; penalties; issuance of permit to carry concealed weapon; exceptions.
1. Except as otherwise provided in this section and NRS 202.355 and 202.3653 to 202.369, inclusive, a person within this State shall not: ...
(d) Carry concealed upon his or her person any:
(1) Explosive substance, other than ammunition or any components thereof;
(2) Dirk, dagger or machete;
(3) Pistol, revolver or other firearm, or other dangerous or deadly weapon; or
(4) Knife which is made an integral part of a belt buckle.
==================================
As far as I can determine there is NO exception to this that specifies doing so on your own, or others, private property, so it would seem to be a felony to do so. Again, IANAL and I do not pretend to offer legal advice.
