I've been to Vegas a few times before I got my CHL. A little burnt out on it, but I like the option of carrying if I ever choose to go back.
I think Utah would be recognized as well, which is the go-to CHL for lots of people outside Texas because of the ease of finding UT CCW instructors nationwide.
I skimmed through the bill and it looks like they may have unintentionally (or intentionally?) made airsoft guns, paintball markers, corn/potato launchers, and shirt cannons match the definition of "firearm" under their state law.
(b) “Firearm” includes, without limitation, a pistol,
revolver, rifle, shotgun, machine gun, submachine gun, black
powder weapon, muzzle-loading firearm or any device which is
designed to, able to or able to be
readily converted to expel a projectile through
the barrel by the action of an explosive,
other form of combustion or expanding gases.
