3. If a board of county commissioners in a county whose population is 700,000 or more has required by ordinance or regulation adopted before June 13, 1989, the registration of a firearm capable of being concealed, the board of county commissioners shall amend such an ordinance or regulation to require:
(a) A period of at least 60 days of residency in the county before registration of such a firearm is required.
(b) A period of at least 72 hours for the registration of a pistol by a resident of the county upon transfer of title to the pistol to the resident by purchase, gift or any other transfer.

3. If the governing body of a city in a county whose population is 700,000 or more has required by ordinance or regulation adopted before June 13, 1989, the registration of a firearm capable of being concealed, the governing body shall amend such an ordinance or regulation to require:
(a) A period of at least 60 days of residency in the city before registration of such a firearm is required.
(b) A period of at least 72 hours for the registration of a pistol by a resident of the city upon transfer of title to the pistol to the resident by purchase, gift or any other transfer.
So, we know the County had pre June 13, 1989 registration ordinance(s), and those ordinance(s) have since been amended and hence require the 72 hour waiting period.
Now, did the cities of North Las Vegas, Henderson, Boulder, and Mesquite also have pre June 13, 1989 registration ordinance(s)? If so, those too would necessarily have had to be amended to require the 72 hour waiting period.
Note that the "72 hours for the registration" is only for residents of the County or City, as the case may be. Which means, I guess a person who is neither a resident of the County or an incorporated city within the county can come into the County or city and purchase a pistol without the "72 hours for the registration."
