Generally speaking, you are prohibited under 18 U.S.C. 922(g) from possessing a firearm if you have been convicted of domestic violence. Your particular charge does not make sense though, because you say you received "supervision" for domestic violence. That's not a possible disposition, because domestic battery is a mandatory conviction offense. I suspect you plead guilty to an amended charge, or else were given a conviction.
