A tiny, tiny percentage of each purchase goes to defray the cost of running this site.
Despite being known best in the commercial market for handguns, Star's primary business has been in many ways their military submachine guns. The fall of the SMG in the 1980s to the 5.56 mm carbine may even have been a contributing cause of their eventual demise.
From just before the Civil War, until the 1990s, one Star SMG model has replaced another in Spanish army service, as well numerous export countries. For more, read up on stocked- and machine-pistols or find your stocked SMG in the progression of Spanish service weapons:
Si35, RU35 & TN35 → Z-45 → Z-62 & Z-63 → Z-70 & Z-70/B → Z-75 & Z-84
The 35 series are first generation, full-stocked, tubular receiver, straight blowback guns. They all fire from an open bolt. The three are basically identical weapons, varying only in the firing assemblies and rates of fire. The RU 35 fired at 300 spm and the TN35 at 700 spm. The Si35 fired at semi auto or either of the rates, but only by setting an amazingly complex configuration of two multi-position switches. These saw some domestic service in the Spanish Civil War, and were offered for sale to the US and British in WWII, but were never bought due to the needless complexity.
Firearms marked 9 mm / 38 are designed to fire .38 ACP and 9 mm Largo ammunition, but NEVER .38 Super. Read more detail on ammunition for older pistols.
I do not have manuals for every pistol shown on this site. However, in many cases there is a related manual. Partly to make the series relationships clearer, and partly to assist with speed and accuracy of updating, all manuals can be found in one place, the manuals page. All manuals available are provided as downloadable PDFs, or you may purchase a printed copy of the entire set of handgun manuals.
I have no manuals for this series of SMGs.
