MP 38/40

MP 40 (maschinepistole 40) is equipped with 9? Submachine gun of 19mm Parabellum cartridge. It was developed in Nazi Germany and was widely used by Axis powers during the Second World War.

It was designed by Heinrich Vollmer in 1938 and was inspired by its predecessor MP 38, which was widely used by infantry (especially platoon leaders and squad leaders) and paratroopers in the East-West front. Its advanced and modern characteristics make it very popular among soldiers, and it is welcomed by countries all over the world after the war. Although Hugo schmeisser was not involved in the design or production of weapons, the allies often mistakenly called him "schmeisser". From 1940 to 1945, Erma Werke produced an estimated 1.1 million vehicles.

Maschinenpistole 40 ("machine gun 40") is a derivative of its predecessor, MP 38, which is based on MP 36, a prototype made of machined steel. The MP 36 was independently developed by Berthold Geipel of Erma Werke and funded by the German army. It incorporates the design elements of Heinrich Vollmer's VPM 1930 and EMP. Vollmer then studied Berthold Geipel's MP 36 and submitted a prototype in 1938 in response to the requirements of the heeresaffenamt (Army weapons Office) for the new submachinegun, which was used as the mp38. Mp38 is a simplified version of MP 36, and MP 40 is a further simplification of MP 38. Some cost saving changes have been made, most notably the wider use of stamping steel instead of mechanical parts.

After Hugo schmeisser, the weapons designer, the allies often referred to the MP 40 as "schmeisser.". Schmeisser designed the MP 18, the world's first mass-produced submachine gun, similar to the MP 40. However, he has nothing to do with the design or development of the MP 40. He has a patent in a magazine

MP 40 submachine gun is an open type, anti blow type automatic weapon. The only firing mode is fully automatic, but the relatively low firing rate can control the trigger for single firing. The bolt has a retractable return spring guide device, which can be used as a pneumatic recoil buffer device. In the early MP 38S, the lifting handle was permanently fixed to the bolt, but in the later production MP 38S and MP 40s, the bolt handle was manufactured separately. It is also safe to push the head of the handle into one of the two separate recesses above the main opening. This action locks the bolt in the up (rear) or not up (front) position. The lack of this feature in the early MP 38 resulted in field access, such as leather harnesses with small loops, to keep the bolts in a forward position.

The MP 38 receiver is made of machined steel, but it is a time-consuming and expensive process. In order to save time and material, and improve the output, the structure of the MP 40 receiver is simplified by using stamping steel and electric spot welding as much as possible. MP 38 also has the function of longitudinal slotting on the receiver and bolt, and provides a circular opening on the magazine shell. MP 40 cancels these functions.

Most MP 38 and MP 40 submachine guns have a unique function, that is, aluminum, steel or bakelite fixed rod or bracket under the barrel. When Sd.Kfz This is used to stabilize weapons when shooting from the side of an open armored personnel carrier like this. 251 half track. A hand guard made of bakelite is arranged between the shell of the magazine and the handgrip of the pistol. The barrel lacks any form of insulation. If it is not placed correctly, it will usually cause burns to the supporting hand. The MP 40 also has a forward folded metal butt, which is the first butt for submachine guns, so the folded total weapon is shorter. But this inventory design is sometimes not enough for tough battles.

Although the MP 40 is usually reliable, its main disadvantage is its 32 magazine. Unlike the double row double feed magazine blade on Thompson m1921-28 variant, the MP 40 uses a double row single feed magazine. Single feed blades increase friction with the rest of the blade holder moving up the feed port, sometimes leading to feed failure; the presence of dust or other debris exacerbates the problem. Another problem is that the magazine is sometimes misused as a handheld device. When hand pressure on the magazine body causes the magazine lips to move out of the feed line, this can cause weapons to fail because the magazine does not hold the magazine firmly. German soldiers were trained to hold the handle on the bottom side of the weapon or the magazine case with a supporting hand to prevent feed failure.
