There are several parts to the answer.
Part 1: There is no handgun registration in Mississippi. You can sell a handgun to another person who isn't restricted in a personal transaction and nothing is required by law as long as the other person also lives in MS. You can, if you choose, print up a bill of sale, so you have evidence that you sold the gun.
Part 2: You can also, if you choose, go to a gun shop or any FFL holder and have them process a transfer. Some dealers won't process transfers between two individuals. The ones that do, will charge a fee, usually somewhere between $25 and $100.
Part 3: If you're talking about a gun that has been stolen (or missing), you should file a police report, but there isn't really any way to "get it out of your name" because, strictly speaking, it isn't "in your name."
I know of no gun registeration in Maryland. No such thing as a unregistered gun.
What state?
Yes
in MOST of the US, there is no requirement to register a gun.
OKAY so what is your queston?
See the link below marked CANADIAN GUN LAW.
Connecticut is not a very gun friendly state. No.
Well, the answer is no, but Arizona does not have gun registration, so if you can carry a gun in Arizona, you can carry any gun you legally own or possess.
Indiana does not have gun registration. If you're carrying your firearm in the legal and prescribed manner, there is no requirement for it to be registered.
Depends on the law where YOU are. In MOST of the US, there is no requirement or procedure to register a gun- popular belief notwithstanding.
You must have a permit for any gun. If you are caught with an unregistered gun (no permit), you will get a minimum jail sentence of 1-3 years.
As long as you legally possess the gun, none. Texas does not require registration of ordinary Title I firearms.
