Star produced 1911-style pistols in a wide variety of calibers and configurations for more than 50 years, including several models with shoulder stocks. Two of the later such models were the MMS and MB. These were standard 5 inch barreled pistols shipped with wooden combination holster stocks and three magazines – one 8-round, one 16-round, and one quite long 32-round. The MMS was chambered for .30 Mauser (7.63x25mm), and 1,174 of them were made between 1971 and 1985. The MB was in 9mm Parabellum, and 1,757 were made in two runs, 1956-1960 and 1972-1975. Both patterns have been added to the list of stocked pistols exempt from NFA requirements, happily.
For more information on these and all other Star handguns, I recommend Leonard Antaris’ book, Star Firearms:
