The Helwan M58 is a semi-automatic pistol that was manufactured in Egypt by the state-owned Maadi Company in the late 1950s and early 1960s. The pistol is a copy of the Beretta M1951, which was originally designed in Italy.
The Helwan M58 is chambered in 9mm Parabellum/Luger (also known as 9mm Long or 9x19mm), which is a popular cartridge for pistols and submachine guns. The pistol has a 8-round magazine capacity and features a single-action trigger, an external hammer, and a safety/decocker lever.
The Helwan M58 has been used by the Egyptian military and police, as well as by civilians in Egypt and other countries. The pistol is generally considered to be a reliable and affordable firearm, but it has also been criticized for its heavy weight, somewhat rough finish, and limited accuracy at longer ranges. Overall, the Helwan M58 is an interesting piece of firearms history and may appeal to collectors or enthusiasts of military-style pistols.
