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