Lots of people are against this because they probably see owning a gun as dangerous in society.
For the simple reason that there is no valid reason to have a registry.
So many people are against gun cabinets because children can easily open them when parents forget to lock them and get at the guns. Thieves can easily break into gun cabinets.
Some makers offer historical letters. No, there is no registry that you can access.
Because if you are against gun safety, you're probably dangerous when handling a gun. Many people that are not for gun safety never will and don't know as much as they probably should know about their gun/guns they own.
You need a lawyer.
Gun registration is regulated by state. There is no federal gun registry, yet. You have to check with your state's gun laws.
In the United States, there is no federal law requiring a national gun registry. However, some states have implemented their own gun registration laws at various times. The Gun Control Act of 1968 established federal regulations on firearms, including the requirement for manufacturers and dealers to keep records of firearm sales, but it did not create a national registry of gun owners. Consequently, the specifics of gun registration depend on individual state laws rather than a federal mandate.
It killed lots of people who were fighting against :)
No, because they are mentally unfit to have a gun. It is against the law to let someone mentally ill own or have a gun.
That largely depends on why cops are in your house in the first place. If you are arrested for something, a loaded gun can be used to bring heavier charges against you. In some jurisdictions (Washington, DC, for instance) the possession of a gun is itself a crime. In most of US keeping a loaded gun is not a problem, unless a minor has access to it. Many people do it for defending against break-ins.

No. Some enthusiasts of a particular gun may keep serial number lists for historical research, but there is no central database of all guns.
