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, presented by an expert firearms instructor, clarifies the legality of open-bolt firearms, using the KG-9 as an example. It explains the open-bolt firing mechanism and details the ATF's historical stance on these designs, noting that while new manufacturing of easily convertible open-bolt firearms is restricted, existing ones are not illegal. The instructor also touches on the historical appeal and simple mechanics of open-bolt designs.
This video focuses on the KG-9, specifically highlighting its identity as the original Tec-9 and its operating mechanism as an open-bolt, semi-automatic firearm. The content appears to be an evaluation or demonstration of this particular firearm model.
This video revisits five classic pistol-caliber firearms (sub-guns) that the host wishes to see in new production. It covers the KG-9/Tec-9, Sterling Mk6, MK Arms Mk760, IMI Uzi, and the MAC-10 in .380 ACP. The discussion delves into their historical context, design variations (open vs. closed bolt), and reasons for their discontinuation or limited availability in modern production.
