Military Weapon used by gangsters, Agram submachine gun. With firearms expert Jonathan Ferguson

The Sten MkI and MkI* submachine guns were developed rapidly during WWII to meet British military needs for a cheap, easily produced firearm. The MkI featured a wooden handguard and grip, while the MkI* simplified this with stamped metal. Both operated via simple blowback from an open bolt, firing 9mm Parabellum.

The Interdynamic MP-9, a Swedish-designed submachine gun, was the precursor to the TEC-9. Designer George Kellgren brought the design to the US, adapting it into the semi-automatic KG-9 pistol for the civilian market. Its simple open-bolt design led to ATF restrictions, necessitating a redesign to the closed-bolt KG-99 and eventually the Intratec TEC-9.

This video delves into the Interdynamic MP-9, the precursor to the TEC-9, highlighting its simple open-bolt design and selector mechanism. It details the fire selector ('F' for semi-auto, 'A' for auto) and the unique notch safety on the charging handle slot. The explanation of the trigger's internal mechanics, particularly the disconnector's role in semi-automatic fire, showcases the firearm's historical engineering.
