The Added Safety on German Inter-War SMGs
This video delves into a unique, often overlooked safety feature found on German inter-war police submachine guns. The presenter explains a rotating locking bar mechanism, identical across various models from the MP18.I to the MP40, including the MP35, MP28.II, and Erma EMPs. This supplemental safety, which locks the bolt forward, was a relatively simple addition requiring minimal modification to the firearm's receiver and bolt. While not present on all police SMGs of the era, it's described as a not uncommon find, highlighting an interesting aspect of firearm evolution and customization in a specific historical context.
