Kinda jumbled up question(s), but...
Take a look at my avatar... you'll see me on my motorcycle with my 1911 holstered on my right hip. You on your scooter are "free" to do the same. It's OC, no matter how you choose to "motorvate."
Now, NLV is a "queer" bird. They have a city ordinance that prohibits "dangerous and/or deadly weapons" in/on a vehicle... meaning "in" your car or "on" your motorcycle/scooter. That ordinance is and is not enforced and I'm not sure if there has ever been a conviction where an accused has taken it to court. Whether or not one who is OCing is "subject" to that ordinance is very much in question/doubt... but that doesn't mean some cowboy NLV cop, seeing you on your scooter with a firearm on your hip, won't pull you over and submit you to the 3rd degree. And, I'm almost sure that if you are stopped while driving your car in NLV for some traffic violation and they casually observe your firearm "in (your) car loaded with one in the chamber," or you give them consent to search and they find it, you are gonna be charged with a violation of the city ordinance. To be just a bit "safer," just OC while in your car; however, that may or may not be "OK" with NLVPD... it's a crap shoot at this time.
