no you can not. buying a firearm off the street means that the gun is illegally seized or bought. due to this, serial numbers are scratched off by the seller (so it can not be traced) which makes registering a firearm impossible. in addition, any attempt to register a firearm without its serial number will cause you to do a lot of explaining to authorities.
Is it the term "off the street" that bothers you? The term "private sale" is more "politically correct". A private sale is legal in most places. If you feel driven to "register" your legal, newly purchased firearm, if it is indeed not stolen, or reported lost by the last owner, there is no reason you cannot register it. Of course, if the serial number is eradicated, the firearm is no longer legal. But why would you want to?
Depends. In MOST of the US, there is no requirement or means to register an ordinary handgun. Depends on the law where YOU live- and you did not share that with us.
No matter WHERE you use a gun, there are laws that govern what you can and cannot do. If you do not know those laws, please do not own a gun.
You would have to go to your local gun shop and register your firearm there. Then, after completing that, you would have to go the gun range and register yourself there, with your gun permit.
