Shooting star Peter Wilson claimed Britain's fourth gold medal of London 2012 in the men's double trap.
Wilson, the world-record holder and world number two in the event, led from start to finish at the Royal Artillery Barracks and was three points ahead going into Thursday afternoon's final after three qualifying rounds in the morning.
And in a tense final shoot-out Wilson missed five shots, including a double as he closed in on gold but his opponents could not take advantage and the Briton eventually finished two clear of Sweden's Hakan Dahlby with a total score of 188 out of 200 shots fired.
Wilson only took up competitive trap shooting in 2006 after a shoulder injury suffered while snowboarding prevented him from playing squash and cricket.
He smashed the world record in Arizona in March, scoring an incredible 198, and is now Britain's first shooting medallist since Richard Faulds won gold in the same event in Sydney 12 years ago.
Wilson needed one hit from the final two targets but nailed both before falling to his knees in tears.
A capacity crowd gave the new Olympic champion a standing ovation before he climbed into the first row of seats to greet his mother and tearful girlfriend Michelle.
As he was surrounded by photographers he simply said: "It's awesome, fantastic."
Dahlby took silver while, behind the celebrations, Russian Vasily Mosin won bronze after a shoot-off with Kuwaiti Fehaid Aldeehani.
