Tech 9 Gun: The Intratec TEC-9, TEC-DC9, KG-99 and AB-10 are a range of semi-automatic blowback pistols. They were developed by Intratec, an American subsidiary of Swedish firearms manufacturer Interdynamic AB. Introduced in 1984, the TEC-9 was made of inexpensive molded polymers and a mix of stamped and milled steel parts. The gun’s simple design made it easy to repair and modify.
The TEC-9 developed a negative reputation for its association with organized crime, street gangs, and mass shootings in the 1990s, including the 101 California Street shootings and the Columbine High School massacre. However, it was a commercial success, with over 250,000 copies sold.
Reputation and legislation
Following the Cleveland school massacre in 1989, the TEC-9 was placed on California’s prohibited weapons list. To work around this, Intratec renamed a variant of the TEC-9 to TEC-DC9 from 1990 to 1994 (DC standing for “Designed for California”). The most noticeable external difference between the TEC-9 and the later TEC-DC9 is that the rings to hold the sling have been moved from the side of the gun with the cocking handle to a removable stamped metal clip on the rear of the gun.
In 1993, the gun was the subject of further controversy following its use in the 101 California Street shootings That same year, California amended the Gun Control Act of 1989 Roberti-Roos Assault Law (AWCA), effective January 2000, to ban handguns with features such as barrel fairings. During the 1990s, the TEC-9 also developed a reputation for use by American street gangs and organized crime syndicates, who were attracted to the high-capacity 32-round magazines and low cost of firearms.
The TEC-9 was produced from 1985 to 1994, when the TEC-DC9 model and variants were banned nationwide in the United States, among the 19 firearms banned by name in the Federal Prohibition of assault weapons (AWB) of 1994, now expired. This ban forced Intratec to cease manufacturing and introduce a newer model.

TEC 9 History & Specs
Originally designed as a fully automatic submachine gun, the TEC 9 was created by Intratec. The American subsidiary of the Swedish company Interdynamic AB. Based on the Carl Gustav M/45, the TEC 9 was chambered in 9x19mm Parabellum and designed for military use. After trying unsuccessfully to find a military buyer, Intratec redesigned the TEC 9 from an open bolt system to a closed bolt system so that it could not be so easily changed to full automatic and marketed it to American civilian shooters. As a semi-automatic pistol, the TEC 9 was made from 1985 to 1990 and made appearances in movies and TV shows like Miami Vice.
After being put on the California Prohibited Weapons List, Intratec renamed the TEC 9 to the TEC-DC9 from 1990 to 1994. Very similar in design, the most noticeable difference was a relocation of the rings that attached to the carrying strap from the side of the gun to a removable metal clip on the back of the gun. Soon, however, the TEC 9 and TEC-DC9 were banned in the United States, forcing Intratec to manufacture the AB-10, a miniature TEC 9 with a threaded muzzle fairing/barrel and 10-round magazine rather than a 20 or 30 round magazine. . The AB 10 was however still compatible with the high capacity cartridges of its predecessors. Intratec went out of business in 2001, ending production of the AB-10.
The TEC-9 was designed by an engineer of Swedish origin, George Kellgren. The first prototypes were developed in the early 1980s at the National Defense Research Institute in South Africa and were submachine guns capable of firing fully automatically. After leaving South Africa, Kellgren marketed the TEC-9 under his own company, Stockholm-based Interdynamic AB. Interdynamic could not find a government buyer. So the TEC-9 was introduced to the American market as an open-bolt semi-automatic KG-9 pistol.
Since it was an open-bolt weapon, it was easy to convert it to full-auto mode. Because of this, the ATF forced Interdynamic to redesign it to a closed-bolt system. Which was more difficult to convert to fully automatic. This variant was called the KG-99. He made frequent appearances on Miami Vice, where he was legally converted to full-auto by the makers of Title II. The TEC-9 was produced from 1985 to 1994.
In 1989, California passed the Roberti-Roos Assault Weapons Ban, which listed the TEC-9 as a prohibited firearm unless registered. In 1990 the TEC-9 was renamed TEC-DC9, DC meaning “Designed for California, to circumvent the ban. A change was made, the sling lugs were moved to the top of the gun.
In 1994, Congress passed the Federal Assault Weapons Ban, the law prohibited firearms with certain cosmetic features. The TEC-9 and TEC-DC9 were listed as banned by name. So Intratec created a ban-compliant version called AB-10 or “After Ban”.
This model lacked the specifically prohibited barrel fairing and threaded barrel and was sold with 10-round magazines. However, the gun was also often sold with 32-round Pre-Ban magazines. In 2001 Intratec went bankrupt and the AB-10 was discontinued.
