Police Chief Glenn Condon says the man was killed by a round from his own pistol, but Condon isn't saying whether the round was a ricochet or an accidental discharge. Foul play is not suspected.
Authorities have not released the man's name but say he was 23-years-old.
The incident occurred Thursday afternoon while at Shooter's Choice on North DuPont Highway.
Condon says there were other patrons in the range at the time.
