The man suffered a wound to the hand.
It happened early this afternoon at the campus radio station KUAF.
Lt. Matt Mills, with the University of Arkansas Police Department (UAPD) says the work study student was showing the gun to another student in the lobby of the station when it accidentally went off.
On the UA Facebook page, the following additional details were posted:
The student was in the station's breakroom, and no one else at the station was injured. The student's wounds - to his hand - were described as non-life-threatening.
University of Arkansas Police receive a call about the shooting at 12:36 and responded to the scene by 12:42. Fayetteville police and first responders also responded to the incident. The student was transported to WRMC.
The pistol was described by police as one designed to fire .410 shotgun shells.
Ironically, the university is hosting a gun forum today.
