The HK P9 is a semi-automatic pistol from Heckler & Koch in 9 mm Parabellum. Designe in 1965 and produced between 1969 and 1978, only 485 of these pistols were produced. A double action version, the more popular P9S was manufactured in greater quantity. Though Heckler & Koch ceased production of this pistol in 1978, it is still available in a licensed Greek version called the EP9S.
