It's not the NV DPS that's doing this, it's the Nevada Sheriffs' and Chiefs' Association (NVSCA).
The NV legislature gave the NVSCA the ability to approve/disapprove which states get honored by NV. [NRS 202.3689]
With the removal of UT and FL from the list of states that NV honors, the only non-resident permit that NV now honors is the NV non-resident permit.
Ever since, UT and FL were added to the list of states that NV honors, more and more people have opted to not get or renew the NV non-resident permit. Since, the FL & UT permits are cheaper and more convienant to obtain than the NV non-resident permit, which requires training in NV & permit application to be submitted in person.
That is a considerable loss of money for NV.
Loss of money for NV business (hotels/resturants/firearms instructors) and loss of money to county/state government agencies (ccw application fees).
Supposedly, the NVSCA is willing to add FL and/or UT back to the list, if the NV legislature changes NV to be like CO and FL.
CO and FL does not honor other states non-resident permits.
