IF you go to prison you are a convicted felon?
If you were sentenced by a judge to spend time in prison for committing a 'FELONY' offense, you are considered a convicted felon.
You could be convicted of a lesser crime, such as a first degree misdemeanor, then be sent to jail/prison and not be considered a convicted felon.
A FELON is someone who has committed a felony offense as codified in state or federal law.
One who has been previously convicted of a crime that carried a sentence of prison incarceration. Actually, the only way to be an ex-felon is to have been convicted, and then acquitted. When you get released from prison, and are no longer state property, you're an ex-convict, but you remain a felon.
The difference between a felon & a convicted felon is past & present. Generally, if one is incarcerated in a prison or detention center is called a "convicted" felon. A felon is anyone who, in part, commits a felony offense. After the incarceration that has been sentenced is served that person is considered a felon or ex-con (ex-convict.).
A lot of felons like to consider themselves ex-felons after prison, even though that's actually an ex-convict, and not an ex-felon. Once you're convicted of a felony, you're a felon. It's not to say that you're condemned to repeat it once you're paroled, but the label doesn't go away. An ex-felon would be someone convicted of a felony, but their conviction was later overturned.
If you are not a convicted felon, or have not been convicted of a crime of Domestic Violence, there is no prohibition against owning or possessing a shotgun, or any other firearm. HOWEVER - if you are a convicted felon or a convicted Domestic Abuser, and you are arrested in possession of a firearm, you could face up to 15 years in prison.
