Just how easy is it to do or what's the process across there?

You are issued one with your greencard upon entry.

So every person is entitled to 1 legally?

Go to a local sporting goods store and fill out some forms for a background check. When the store calls you back you go pick up your gun. Or you just buy one from an individual. Everyone owns a couple dozen here.

Depending on the state, pretty easy if you can pass the The National Instant Criminal Background Check.

If you are an American citizen, can lawfully own a firearm, and choose to purchase from an individual vs a dealer, a private sale is pretty fast.

Hell you can buy one here. No background check required

Unless you�re a convicted felon or convicted of some violent crime like domestic abuse, you�re good to go. And must be over 21.

I know a person that owns 37

Does the same paperwork count for buying from an individual? Not meaning to come across a bit blank about this

Paperwork. Lol

Only if the seller requires it. Its not required.

A few Benjamins will get you just about anything. And then there's the legal options.

So it's really quite easy then?

Some would have you believe you can buy one on any street corner. You cannot. If you do find a street corner where you can, you're more likely to get rolled than leave with a gun.

Quite.

At least in Texas. Your mileage may vary in such wonderful, crime free areas of the country such as Washington, D.C., New York (state and city), Chicago, all of California, and certain others.
Basically just look at a political map of the USA. Red states are easier than blue states to purchase/ own/ carry a firearm.
