Crittenton has been charged with one misdemeanor count of unlawful possession of a firearm, and one misdemeanor count of attempt to carry a pistol without a license ... this according to the Washington Post.
As we first reported, sources say Crittenton threw the gun he pulled into a laundry bin after the incident and someone wheeled it out before anyone knew what went down.
Cops searched Crittenton's home but, we're told, they did not find a weapon.
Arenas pled guilty earlier this month to one felony count of carrying a pistol without a license, and is due to be sentenced in March.
UPDATE: Crittenton's lawyer says there is a plea deal in place, telling TMZ, "With today's misdemeanor plea to possession of an unregistered firearm, [Crittenton] accepts responsibility for his conduct."
