The P-64 is a
double-action blowback-operated pistol. It has a spring extractor mounted within the slide. The rotating slide catch, installed inside the pistol's frame, contains a protrusion which acts as an empty case ejector. The pistol's trigger mechanism includes a disconnector (which ensures semi-automatic-only fire); a double-action trigger (which allows the pistol to be both cocked and fired with one pull of the trigger); and an exposed hammer. The slide features a
loaded chamber indicator (which, both visually and by feel, indicates the presence of a round in the chamber) and a manual safety lever that prevents the weapon from being accidentally discharged with the hammer either cocked or released. This feature also allows a round to be chambered with the safety engaged or toggled off. In the "safe" position, the firing pin is locked and the
trigger bar is disconnected from the hammer notch. If the hammer is cocked and the safety is engaged, the safety will release the hammer. In 1971 the hammer was modified internally, although some 1971 dated examples exist without the modification, those can be distinguished by the absence of an "A" marking on the receiver, behind the grip. In 1973 the trigger mechanism was modified and the hammer was changed to a triangular shape, designed to be easier for cocking with the thumb. The P-64 is fed from a 6-round single-stack box
magazine. After the last round has been fired, the magazine follower lifts the slide catch, which locks the slide open. The slide can then be released by withdrawing the magazine a short distance and pulling the slide back. The pistol is equipped with a fixed front sight, and a dovetailed rear sight with a square notch. The sights are calibrated for firing at 50 m. The all-steel P-64 is manufactured mainly by machine cutting. It is issued with a spare magazine, a leather holster, and a cleaning kit. Often the magazines sold with the pistol do not match the serial number of the weapon. Despite its similarity to the
Walther PP, the P-64 is an original design, holding a Polish
patent, number 54822. The patent applies to the unique disconnector (an elongated plate sliding vertically inside the pistol's frame) which provides an internal safety, decocks the hammer when the safety is engaged, interrupts the weapon's cycle after every shot fired, and allows the weapon to be reloaded with the safety on. Due to its similarities with the Walther PPK, it is sometimes mistakenly referred to as a "PPK clone". It is also commonly referred to as a "Polish Makarov", although the P-64 is not a Makarov, and its only similarities with the Makarov PM are the blowback action, 9x18 "Makarov" chambering, and method of takedown. For importation into the US, target grips are put on the pistol so it will qualify as a "Sporting Pistol" per
ATF regulations, although it is very rare for a P-64 to be sold with the target grips as the original grips are usually replaced by the importers when they arrive at the US warehouse. Many examples imported into the US have very prominent import markings, and any P-64 without import markings or with inconspicuous import markings will earn a premium in the marketplace. The pistol is designed to use steel case ammunition, although brass cased ammunition will function properly as well. ==Operators==
