42-year-old Charles Pike was at the Lions Club Gun Show at the Hot Springs Convention Center in Arkansas. He picked up a revolver from a vendor's table and unintentionally discharged the weapon.
The bullet struck Pike in the left hand, then ricocheted off the floor and struck a 37-year-old man in the left side of the chest. Both men were taken to the hospital for treatment of non-life threatening injuries.
"For some reason we don't know, this particular weapon had a round in it and had an accidental discharge," said the gun show committee chairman.
Police are still investigating the incident.
