in nebraska you can buy handgun ammo at 18. but you have to be 21 to buy a handgun and apply for a CCW permit. CCW in nebraska is only 1 year and 1 day old as of this post, but in our great state you can open carry... while you can do this a lot of places in nebraska i wouldnt recomend running your errands around town holstered up. all it takes is one person to get freaked out and call the cops. and while you may be legal to carry you may be cited for disturbing the peace and laws of that nature.
in 1988 voters passed into law Initiative Measure No. 403 which pretty much tells the state they cant mess with our guns... here is how it goes in the constitution.....
"and the right to keep and bear arms for security or defense of self, family, home, and others, and for lawful common defense, hunting, recreational use, and all other lawful purposes, and such rights shall not be denied or infringed by the state or any subdivision thereof"
while some places like omaha have restricted open carry, in the majority of nebraska outside of the major urban areas open carry is often practiced, mainly by farmers, ranchers and hunters that spend a lot of time in the middle of nowhere. but it still isnt uncommon to see someone with a gun on their hip... things have started to change but for the most part when people see someone carrying a gun out in plain sight they just assume they have the right to do so.
just remember just because you HAVE the right to do something doesnt mean that you SHOULD do it. i do practice open carry sometimes but not around town or heavily populated events..... no need to cause a freak out, this year i will be getting my CCW permit and wont have that problem any more
