Origins of the Tec-9

The story of the Tec-9 begins in Sweden during the 1940s with the development of the Carl Gustav M/45 submachine gun. This reliable military weapon served as the foundation for what would eventually become one of America’s most controversial firearms. Swedish company Interdynamic AB recognized the commercial potential of adapting this proven design for civilian markets.

The Development of the KG-9

Interdynamic AB engineers took the core mechanics of the Carl Gustav M/45 and reimagined it as a semi-automatic pistol. The resulting weapon retained the original’s blowback-operated system, which uses the energy from fired cartridges to cycle the action automatically. This simple yet effective mechanism made the weapon both reliable and cost-effective to manufacture.

The initial civilian adaptation became known as the KG-9, marking the first step in the weapon’s evolution from military submachine gun to commercial firearm. Key characteristics of this early design included:

Open bolt pistol configuration that fired from an open bolt position
Large-capacity magazine capability
Compact design suitable for civilian ownership
Affordable manufacturing costs

The Decision Behind Creating a Semi-Automatic Version

Interdynamic AB’s decision to create a semi-automatic version stemmed from growing demand for military-style weapons in civilian markets. The company saw an opportunity to bridge the gap between military functionality and legal civilian ownership requirements.

Design Philosophy and Production Approach

The KG-9’s design philosophy centered on simplicity and reliability. Engineers stripped away unnecessary components while maintaining the weapon’s core functionality. This approach resulted in a firearm that could be produced quickly and sold at competitive prices.

Lasting Influence of Swedish Origins

The Swedish origins of what would become the Tec-9 established several design principles that would persist throughout its evolution. The emphasis on straightforward mechanics, high-capacity magazines, and affordable production costs became hallmarks of the weapon’s identity. These foundational elements would prove both commercially successful and legally problematic as the weapon transitioned from its Scandinavian roots to American manufacturing.

Transition from KG-9 to TEC-9

The transformation of the KG-9 into the TEC-9 marked a pivotal moment in firearms manufacturing history, driven by regulatory pressures and business necessity. When the original KG-9 faced scrutiny from federal authorities, Intratec company history took a dramatic turn as the manufacturer sought to navigate increasingly complex legal waters.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) classified the original KG-9 as a machine gun due to its open bolt firing mechanism, which could potentially be converted to full-automatic fire with relative ease. This classification threatened to eliminate the weapon from the civilian market entirely, forcing Intratec to redesign their flagship product.

Engineering the Solution

Intratec’s response involved a fundamental redesign of the firing mechanism. The company developed the KG-99, which featured several critical modifications:
