Regardless of how exactly you travel, (by whatever convenance) workout your itinerary on the USCCA Reciprocity, and state laws app.
Whatever state you visit you need to be in compliance with their laws.
You start by plugging in your own state, and then the others.
They expanded how many at once you can check.
Be sure that you have all your legal travel documents, state photo id drive licenses, and any CCWs that you might also have.
Before you cross any state lines make sure you are good to go as is when you cross that line.
It will do you little good if you soon get pulled over, and had not made any adaptations to their laws that you should have.
If your carry weapon can accommodate various magazines at different capacities that might be better than taking various weapons unless they suit a particular preference for a different situation, like a smaller gun that is better suited to the beach, more easily concealed than your EDC in street clothes . Maybe a BUG, backup gun.
Maybe if you off-road into bear country you might want a .500 cal. open carry.
Think about all your situations, and choices for each.
You don’t want your whole arsenal to lug around, and maybe get lost, or stolen.
But, you don’t want to limit your chooses either for what you want to enjoy. And, what you need to support each weapon.
If you got one, or a very few that will adapt to your itinerary that is what is best to take.
Some professional drivers only take 10 round limited capacity magazines so as not to worry about forgetting to change to that when going into restricted capacity states.
Also, some states restricted different types of ammo, like no explosive, or armor piercing, that type of thing.
NJ doesn’t allow JHP, our most common defensive ammo.
Try to bring what will be compliant everywhere, and not have to worry about changing from state to state. That might be NATO FMJ.
It is times like this when we all wish all states had one simple universal constitutional carry law with universal Reciprocity, and a not a lot of variables between each state.
All you can do for now as a reasonable gun owner is your homework, a contrast, and comparison of each state that you will visit.
Cut the variables, and changes necessary to a minimum as best you can.
If you can get by with one weapon, one magazine capacity, and one type of ammo, all the better.
Just that I would bring more of that type of ammo, and more pre loaded magazines if your capacity is restricted anywhere on your itinerary.
If you can, and would prefer to bring less restricted magazines mark them with a Sharpie with the two letter postal abbreviations of the state/s they are allowed in, and be sure that’s what is loaded into your weapon, and are carrying for backup on your person, or in your reach.
Not to have any issues about that with any LEOs.
