At the end of the 1960s, HK in Oberndorf decided to adapt the proven roller-delayed system of the G3 assault rifle to a pistol – the birth of the Heckler & Koch P9S. This unusual gun was manufactured for 25 years, also serving in the GSG 9 (the German police tactical unit) – an additional reason to take another look at it, this time focusing on the history, models, and operation of the gun.
When the first roller delayed system pistols went into production at Heckler & Koch in 1969, the gun was still called the P9. However, the P9 was not particularly successful, because nine years later manufacturing ended after only 510 units. Instead, the P9S variant was launched in 1970, whose production did not end until 1995. Except for the traditional double action, the P9S did not differ significantly from the pure single action P9 model. At that time, the new pistols from Oberndorf were characterized by three features: the barrel with polygonal profile, the cold stamping of essential parts with no machining and, of course, the roller delayed blowback system, similar to the system used in the Heckler & Koch G3. Polygonal barrels are still found today in pistols from various manufacturers, but stamped frames or slides are not, and locking rollers have never been a priority for many pistol manufacturers. Apart from the P9/P9S, however, rollers as a locking element can also be found on the Czech vz. 52 or the rare Korriphila HSP 701 pistol. The first functional test sample was produced in Oberndorf as early as 1966. Early prototypes mostly still had a lug for the attachment of a shoulder stock and a full-auto trigger assembly, the very first original P9 even featuring an external hammer. Although all later P9 and P9S also have a hammer, it is well protected from impacts or dirt inside the construction. The steel grip and the magazine area were also completely covered by the polymer grip shell and the front of the frame, from the grip area to below the muzzle, by the trigger guard, also made of polymer.
Early years: the P9S from Heckler & Koch

The lever behind the trigger serves for (de)cocking, besides being the slide stop.
Early P9S can be recognized today by the shape of the grip, the upwardly curved trigger guard without the aggressively shaped finger rest of later versions, and by processing details such as the high-gloss blued slide sides. The P9S in the images with the number 100008 dates from the earliest stage of serial production, which started with the number 100001. Despite the double-action trigger, there is still no "S" in the model designation, because the manufacturer had to use a stock of completed P9 slides first. On later samples, there is a small "s" between the manufacturer's logo and the model name, but there was just enough space for that.
Not only 9mm: the variants of the Heckler & Koch P9S:

The P9S from early production (right) still has the small cocking indicator pin above the beavertail and a grip with a more pronounced thumb rest.
In the 1970s the P9S was redesigned several times – as can be seen in the ejection port on the right, which was enlarged – or the rectangular cocking indicator pin of later versions. Speaking of variants: as standard, HK supplied the P9S pistol in 9mm Parabellum caliber with a four-inch barrel and fixed sights. From 1973 on, however, a few examples were also produced in 7.65 mm Parabellum and 3 years later the much more successful models in .45 ACP were launched.
The company produced the P9S both in 9 mm Luger and in .45 ACP in several sports versions, recognizable by the adjustable micrometer rear sight. In addition to four-inch models, the company also introduced models with a barrel extended to 5.5 inches (141 mm) and a barrel weight. Typical for the sports models was also the trigger stop, which can be raised inside the trigger guard. This effectively limited the enormous overtravel of the P9S trigger following the release. When raised, however, the trigger stop prevents the hammer from being released in DA mode so the gun effectively becomes SA only in the sports models with the raised trigger stop.
