In the bond film Skyfall and its opening sequence, one of the villains had a full auto pistol a beta mag though it did not have 2 systems like that has. He must have fired 1000 shots in the opening scene and never reloaded. Most people in the theater probably do not catch that but it was annoying as hell to be insulted like that.
