The P9 pistol was designed by the famous Heckler & Koch company during the first half of the 1960s after much testing and prototyping. The P9S is an interesting design that became the first to use a variation of H&K's roller-delayed blowback system in a pistol format and polygonal rifling, now common in H&K designs. The P9 is manufactured from a stamped steel frame overmolded in polymer. The P9S trigger operates as a traditional double action with a lever on the left side of the pistol grip to both decock the hammer and re-cock it for a single action first shot. The hammer is concealed within the slide with a protruding pin at the rear of the slide as a cocking indicator. This pistol features fixed 3-dot sights and 2-position safety and includes two 9-round magazines. Its grips, its metal, and its bore are all in very good condition.
