Beretta 92F (9x19mm) used by Bruce Willis in Die Hard. This is the screen-used gun from the film; note the extended mag release and slide release, which were modifications made specifically for Bruce Willis.ans Gruber (Alan Rickman) carries a hard chrome Heckler & Koch P7M13 as his main weapon, notably using it to threaten Joseph Takagi (James Shigeta) and Harry Ellis (Hart Bochner), and then brandishing it at the climax of the film, holding McClane's wife Holly (Bonnie Bedelia) at gunpoint.
