Along with the new changes in NV CCW, SB92 was also passed and signed into law.

SB92 was suppose to get rid of the Clark County "blue card" registration system. However, it was amended and compromised.
Under the new registration system, non-residents of Clark County have to register their handguns with LVMPD if they are staying longer than 60 days in Clark County. Residents of Clark County have 72 hours to register their handguns.
This new system goes into effect by 01-01-2008.
So, until 01-01-2008, the old "blue card" registration is still enforced in Clark County. If you are staying longer than 24 hours in Clark County you have to register your handguns.
