According to my research, Blackpowder firearms aren't classified as firearms on the federal level, therefore, there's usually no paperwork involved in buying them interstate and they can be mailed by the Postal Service to an individual's home instead of an FFL.
Several states have differing opinions on BP, though. Some allow BP longarms of all types to go without any sort of registration or paperwork, but treat BP handguns as regular handguns. Some treat inlines as regular firearms. Some mail order companies want a signed statement or a photocopy of your DL as proof that you're of age according to their state laws or their personal preference to CYA.
On a federal level, convicts are allowed to own BP firearms, as are people with Domestic Violence records, as long as they're off probation. (I know a couple of non-violent felons who are actually allowed to possess regular firearms during hunting season, they have a document from a judge). I know a couple of guys with DV's that own several BP handguns and rifles. There is a huge gray area concerning the conversion cylinders. I guess as long as they are able to remove the cylinders before the law gets to them, they're okay.
In MS, you are not allowed to carry a BP handgun concealed without a CCW permit. Most states have laws concerning "nonfirearms" used as firearms during a crime, like replicas, water pistols, or even your finger hidden in your pocket. We had a guy recently sentenced to using a firearm to rob a bank who used his fingers in his pocket in his attempt. His sentence would have been lighter if he used a knife out in the open, unless he called it a gun.
States also have laws concerning the legal minimum age to own and purchase BP, caps, and guns. Unfortunately, I've been legal for 20 years, so I don't know what the minimums are here in MS. I'm assuming the minimum age is 18, but I can't remember if Walmart is enforcing it as strongly as selling "R" rated movies or "M" rated games.
No one has challenged me, but I have a gray beard and look fat and respectable.
In MS, your motor vehicle is an extension of your home; you can carry loaded handguns in your car, motor home, or even on your bike. You can wear a concealed weapon while driving your motor vehicle or in your home, or on your property or business (if you're driving in your home..sweet!
). Your employees and guests can carry concealed, likewise. Of course there's a gray area when you get off your bike. You have to be careful or be accused of brandishing while you're stashing your pistol away. MS also allows open carry, but I've only seen it a few times. We're allowed to carry unloaded long arms in our vehicles, that's an anti-poaching thing. I saw a guy on the back of a rice rocket wearing insulated coveralls on his way home from hunting with a rifle slung across his back. MS also made it illegal for employers to discriminate against employees who have weapons in their car.
MS has no state or local registration process, there's just the yellow sheet if you buy it new, that's it. The state even passed a law prohibiting counties and municipalities from creating gun laws. One of my friendly neighborhood gun dealers told me she's had a lot of people moving from other states that bring their firearms in to "register" them. She's told them and argued with them and they leave upset that they couldn't register them there and go to another store to get the same thing told to them.
