It depends on a couple of factors. One, it depends on where you are (there are some places where you cannot legally own or possess a gun). Two, it depends on what you're using it for.
If you are in the United States, it's legal to own guns in every state (although some states have restrictions that others don't, and a couple of cities have some restrictions). Otherwise, it is perfectly legal to use a gun for a legal purpose, such as hunting, target shooting, or self-defense. Of course, it is not legal to use a gun for an illegal purpose, and it is illegal to possess a gun during a crime, even if you otherwise legally possess the gun.

As long as you follow all the rules and regulations, no.
