Design Details
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 the 1970s the trigger mechanism was slightly modified and the hammer spur was enlarged.
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. This pistol has a harsh recoil caused by its relatively small size coupled with the potent 9x18mm Makarov round.
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 disconnecter (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.

Famous quotes containing the words design and/or details:
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“Anyone can see that to write Uncle Tom’s Cabin on the knee in the kitchen, with constant calls to cooking and other details of housework to punctuate the paragraphs, was a more difficult achievement than to write it at leisure in a quiet room.”
—Anna Garlin Spencer (1851–1931)
