Found this tidbit over on IMDB

He was cautious in his interaction with the young children who were fans of Adventures of Superman (1952) because they often tried to test his "invulnerability" by assaulting him. At one appearance a young boy came up to Reeves, pulled out a pistol and pointed it at him. The boy had taken the weapon, a Luger that his father had brought home from World War II, to see if "Superman" really was invulnerable. Reeves convinced the boy to give him the gun by saying that someone else would get hurt when the bullets bounced off of "Superman".

 

He later disproved that by shooting himself in the head with a Luger.
