[1] As a result of the lack of a competitive firearms market in Sweden, Interdynamic AB set up a subsidiary in the United States to sell the KG-9.

Called Interdynamic USA, this company eventually became Intratec when George Kellgren left the company and Carlos Garcia renamed it Intratec, and continued to sell variants of KG-99, later known as the model it would be known for, the Tec-9.

[2] Intratec was known for numerous handgun designs using polymer frames and steel stampings.

The design is a derivative of Sirkis' original all-steel Sardius SD-9 pistol.

The TEC-38 is a polymer-framed two-shot derringer chambered in .38 Special, made for a short period from 1986-1988.
