premise: The Beretta 93R is a selective-fire machine pistol, designed and manufactured by Italian firearms manufacturer Beretta in the 1970s for police and military use, that is derived from their semi-automatic Beretta 92. The "R" stands for "Raffica", which is Italian for "volley", "flurry", or "burst" (sometimes spoken "R" as ""Rapid"" in English).
hypothesis: In the 1970s, the Beretta 93R was used in Italy, but not by civilians.
reason: The Beretta was used by military and police, and wasn't sold to civilians. This may be difficult because the original context never explicitly mentioned civilians, but a gun developed for military and police couldn't be purchased by civilians then.
