18 USC 922(g)(9)

 This is often inaccurately shortened to misdemeanor domestic battery.  It is not.  It prohibits possession if you have been convicted of the much more narrowly defined "misdemeanor crime of domestic violence" which is at 18 USC § 921(a)(33).  Even then, first conviction is only a five year disqualifier.  It still fails the Bruen test; I am not aware of any firearms disqualifier for domestic violence in the Founding Era.
