The music of the one that starts Licence to Kill emphasizes the Darker and Edgier nature of the film compared to its predecessors. Timothy Dalton had the same for his two films.He's also the only Bond to hold his gun with two hands, starting with, again, The Spy Who Loved Me. He was the first to not wear a hat, in the opening to Live and Let Die and the first to perform it while wearing a tuxedo, in the opening of The Spy Who Loved Me. Roger Moore had two of them for his entire tenure.George Lazenby's hatted silhouette kneels down to shoot and vanishes when the blood drips in On Her Majesty's Secret Service.Simmons' gun barrel was the only one to have Bond slightly hop as he turns to shoot his opponent.It wasn't until Thunderball that the Bond actor of the film performed the silhouette, namely Sean Connery, also wearing a hat. No, with the hatted silhouette of stuntman Bob Simmons. The Gun Barrel usually opens the Action Prologue. James Bond is, for obvious reasons, the Trope Namer and Trope Maker.
