Most of the policemen in the film, including Det. Nicky Dimes (Chris Penn) carry Beretta 92FS pistols, as was issued to the LAPD at the time. The Italian gunman Luca (Paul Ben-Victor) also draws his own Beretta during the final standoff.
Beretta Inox
Frankie (Frank Adonis), another of the Mafioso, carries a Beretta Inox, which he holds to the head of Clifford Worley (Dennis Hopper) and later a woman he holds hostage in the hotel.
Frankie also draws a stainless revolver after handing his shotgun to "mad dog" before they enter the hotel room in the climactic shootout. Anyone know what this weapon is? It looks like a Smith and Wesson but Im unsure of the model. Theres also a snub-nosed revolver on the bed during the "loading up" scene.- Spoon
