Why the Nazis spent so much time making a worse STG-44: The MP43/1 with Jonathan Ferguson

This video examines an experimental MP43/1 variant featuring a gas-delayed blowback system, a departure from the standard StG-44's gas piston operation. The prototype utilized a complex muzzle device and a stronger MG42 recoil spring, but was ultimately rejected for failing to offer manufacturing or cost advantages over the original design. The system's designer, Karl Barnitzke, later applied similar principles to other successful firearm designs.

Quick Summary

The experimental MP43/1 utilized a gas-delayed blowback system, a radical departure from the standard StG-44. This prototype featured a complex muzzle device and modified internals, including a stronger MG42 recoil spring, to manage gas pressure for cycling. It was ultimately rejected for failing to offer manufacturing or cost advantages.

Frequently Asked Questions

What made the experimental MP43/1 different from the standard StG-44?

The experimental MP43/1 featured a gas-delayed blowback operating system, a significant departure from the StG-44's conventional long-stroke gas piston. This involved a complex muzzle device and modified internals to manage gas pressure for cycling.

Why was the experimental MP43/1 gas-delayed blowback system developed?

The system was designed by Karl Barnitzke to explore alternative operating mechanisms. It aimed to use gas pressure at the muzzle to delay bolt opening, potentially offering different cycling characteristics or efficiencies.

What were the key modifications in the experimental MP43/1?

Key modifications included bypassing the original gas block, turning down the barrel, sleeving it to block the original port, and fitting a unique muzzle device. The bolt carrier was also modified, and a stronger MG42 recoil spring was used.

Was the experimental MP43/1 adopted by the Nazis?

No, the experimental MP43/1 was not adopted. A weapons committee assessed it in August 1944 and rejected it because it offered no advantages in cost or manufacturing ease over the standard MP44, despite its technical innovation.
