In design and function, the P-64 is similar to the Walther PPK, though some internals are different and are covered by a Polish patent. It is a double-action (DA) blowback design with a hammer-drop safety. As with the PPK, it incorporates a loaded-chamber indicator, which may be seen or felt. It is larger in diameter than that of the PPK and, hence, easier to see or feel. When chambering a round, the safety lever may be placed in the down position, which will lock the firing pin and disconnect the trigger bar. I always liked this feature as it allowed a round to be safely chambered without having to lower the hammer manually on a loaded chamber. As with the PPK, the slide locks open after the last round is fired and may be released by pulling it backwards and releasing it after a reload is completed or after removing the empty magazine. A bottom magazine release, which catches a protrusion on the rear base of the magazine, is used. Since the magazine has a finger rest hook, by catching this hook and depressing the magazine release button, the mag may be removed readily.
As with a PPK, the P-64 disassembles by pulling down on the trigger guard and lifting the slide off the rear of the frame. I’ve learned from many years of using PPKs that the easiest method is to pull the front of the trigger guard down and then press it slightly to the left under the frame using the trigger finger while pulling the slide to the rear and off. There has been corrosive 9x18mm ammunition sold in the U.S. so with any ammunition about which you are unsure, a good cleaning with hot water and GI bore cleaner is advised. Fortunately, today most 9x18mm ammunition encountered is non-corrosive.
