The Intratec TEC-9 or TEC-DC9 or AB-10 is a blowback-operated semi-automatic pistol, chambered in 9×19mm Parabellum. It was designed by Intratec, an American offshoot of Interdynamic AB. The TEC-9 was made of inexpensive molded polymers and a mixture of stamped and milled steel parts.


Swedish company Interdynamic AB of Stockholm designed the Interdynamic MP-9 9mm submachine gun. Intended as an inexpensive submachine gun based on the Carl Gustav M/45 for military applications, Interdynamic did not find a government buyer, so it was taken to US market as an open-bolt semi-automatic KG-9 pistol. The open bolt design was too easy to convert to full-auto. Because of this, the ATF forced Interdynamic to redesign it into a closed-bolt system, which was harder to convert to full-auto. This variant was called the KG-99. It made frequent appearances on Miami Vice, where it was legally converted to full-auto by Title II manufacturers.[2][3] The KG-9 and KG-99 have an open end upper receiver tube where the bolt, recoil springs and buffer plate are held in place by the plastic/polymer lower receiver frame. This design only allows for 115 grain 9mm ammo. If heavier grain ammo or hot loads are used, the plastic lower receiver will fail/crack rendering the firearm unusable. The later model TEC-9 and AB-10 have a threaded upper receiver tube (at the rear) and screw on end cap to contain the bolt , recoil spring and buffer plate, even if removed from the lower receiver. This solves the problem of lower receiver failure when using "hot ammo".

The TEC-9 was produced from 1985 to 1994.[4]

After the Cleveland School massacre, the TEC-9 was in California's list of banned weapons. To circumvent this, Intratec rebranded a variant of the TEC-9 as the 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 rings to hold the sling were moved from the side of the gun with the cocking handle, to a removable stamped metal clip in the back of the gun. The TEC-9 and TEC-DC9 are otherwise identical.[citation needed]

The TEC-9 and, eventually, TEC-DC9 variants were listed among the 19 firearms banned by name in the USA by the now expired 1994 Federal Assault Weapons Ban (AWB).[5] This ban caused the cessation of their manufacture, and forced Intratec to introduce a newer model called the AB-10, a TEC-9 Mini without a threaded muzzle/barrel shroud and limited to a 10-round magazine instead of a 20- or 32-round magazine. However, it accepted the standard capacity magazines of the pre-ban models.

The weapon was the subject of controversy following its use in the 101 California Street shootings[6][7] and later the Columbine High School massacre.[8][9] California amended its 1989 Roberti-Roos Assault Weapons Control Act (AWCA) later in 1999, effective January 2000, to ban firearms having features such as barrel shrouds.[10][11]

In 2001, the Supreme Court of California ruled that Intratec was not liable for the 1993 California Street attacks.[8] In that same year, the company went out of business and production of the AB-10 model ceased.[8]

Although still found on the used firearms market, the TEC-9 and similar variants are banned, often by name, in several states including California, New York, New Jersey[12] and Maryland.
