The Port Said Submachine Gun became nothing more than an Egyptian copy of the Swedish Carl Gustaf m/45 SMG series produced locally and under license. The original gun appeared in Sweden (based on the Bergmann MP18 and MP35 models) after the fighting of World War 2 (1939-1945) and eventually found a few takers globally - including the United States who pressed them into service during the Vietnam Conflict (1955-1975). The Egyptians were given proper assistance in the local production venture through delivery and training of the tooling required. This version is faithful to the form and function of the Swedish model.
The submachine gun was chambered for the widely accepted 9x19mm Parabellum pistol cartridge firing from a 36- or 50-round straight detachable box magazine. The magazine was inserted into a well ahead of the trigger group. A simple grip handle was fitted aft of the trigger. Dimensionally the weapon was compact for troops to carry it into confined spaces (hence its use in jungle warfare by the Americans). The stock was a folding wire-type to further increase portability of the weapon. Internally, a blowback system of operation was relied upon and firing was limited to full-automatic-only.
Simple, robust, reliable and effective, the Port Said and its cousins were well-respected weapons - some still in service today (2016).
A simpler production version followed as the "Maadi Akaba" in the 1970s. In this form, the barrel jacket was removed and the barrel itself shortened to save on weight at the expense of range and accuracy. A telescoping wire shoulder stock also replaced the original folding wire. Functionality of the weapon remained largely the same.
