Originally called the Model 48, FEG designed this handgun, based on the German Walther PP/PPK pistol series, just like many of the other post-World War II Hungarian pistols. The pistols were produced primarily for the civilian market, and export. Most commonly chambered in 9mm Browning Short (.380 ACP) ammunition with a 7-round magazine capacity or .32 ACP with an 8-round magazine, they are factory sighted for 25 metres.
A smaller version known as the APK9 was made for export to Egypt, but very few of these pistols were made.
The AP9 is a self-loading pistol using the blowback mechanism with a double-action trigger, has a rotating safety/decocking lever on the left side of the slide, and is equipped with a firing pin safety mechanism, which prevents the firing pin from striking the primer of a loaded cartridge, unless the trigger is pulled. Field-stripping the pistol for cleaning is accomplished identically to the Walther PP pistol.
The frame is made of aluminum alloy and the slide is made from steel.
