My name is XXXXX XXXXX I am a criminal
lawyer. The Federal government has its own definition of what a domestic violence offense is for purposes of determining whether one is eligible to carry a firearm.
If the crime fits the definiton of domestic violence, it can cost you your Federal gun rights regardless of whether the state labeled it as such or not.
The Federal definition can be found in 18 USC 921:
"(A) Except as provided in subparagraph (C),  the term “misdemeanor
crime of domestic violence” means an offense that—
(i) is a misdemeanor under Federal, State, or Tribal  law; and
(ii) has, as an element, the use or attempted use of physical force
, or the threatened use of a deadly weapon
, committed by a current or former spouse, parent, or guardian of the victim,
by a person with whom the victim shares a child in common
, by a person who is cohabiting with or has cohabited with the victim as a spouse, parent, or guardian, or by a person similarly situated to a spouse, parent, or guardian of the victim.
So, if the victim in this instance was a present or former spouse, a person you lived with with whom you had a child, your offense would be an act of domestic violence. Otherwise, it would not be. If the victim were your parents or a sibling, for example, that would not meet the Federal definition of domestic violence.
So if you have your state gun rights and cannot clear the NICS check, you ought to be able to appeal it on that basis to the FBIs gun unit. You can read more about how to do that here.
