The short answer is, you can't.
The longer answer is, handguns aren't registered in most of the U.S. States, and in the few states that do require it, the information is not available to the general public.
Where are you? Most U.S. states do not require registration.
No.
yes it does. :)
No, it does not.
Since the state of Texas doesn't require handgun registration, the answer is, zero.
Generally speaking, the answer is, you can't. In the U.S. there is no national registration, and only a few states require registration, so it probably isn't registered. In the few states that require registration, the information isn't available to the general public.
It depends on what you mean. If you legally possess the handgun, then it is legal to have it in Tennessee. Tennessee doesn't require any kind of registration, however, you do have to have a valid handgun carry permit to legally carry it on your person or have it accessible in your vehicle.
It depends on where you are. In the U.S. only a few states require registration and there is no federal registration.
It depends on what you mean. If you mean that you want to find the age of the gun based on the serial number, there are a few online sources, such as the Blue Book of Gun Values. If you mean that you want to find out if it is registered, no.
Please do not write in this area, or your question goes to the "already answered" bucket- I caught it by chance. California does not require registration of rifles and shotguns. Handgun registration is not a matter of public record.
They can forbid you to possess any firearm.
None of my guns are registered in Ohio, but I don't live or visit there, so there is no penalty at all.
