Developed in the 1930s by Bergmann, the streamlined MP35/I was manufactured by Walther and Junker & Ruh, with the primary recipient being the Waffen-SS. Blade front and tangent rear sights, with a two-port muzzle brake integrated into the heat shield and a set of model markings, "ajf41" manufacturer code (Junker & Ruh AG, Berlin) , and "SS ZZA1" proof mark. A safety switch is installed on the left side of the receiver, with a two-stage trigger integrating a spring loaded catch positioned near the bottom of the trigger; pulling high on the trigger fires one shot, pulling low disengages the catch and allows the trigger to run full auto. With a smooth pistol grip stock, forearm grasping grooves, brown leather sling and flat steel buttplate. Two extra stocks, trigger housing and bolt. Magazine absent.
