Federal once manufactured a 9mm revolver cartridge with rim, similar in concept to the .45 Autorim cartridge.
Not quite. The .45 AutoRim was designed to chamber in a .45 ACP chambered revolver, which required a thick rim. The 9mm rimmed cartridge was a revolver cartridge from the git-go. That is, no 9mm Parabellum ammunition could be used with clips.
