when using hot ammo. Reputation and legislation Following the 1989 Cleveland School massacre, the TEC-9 was placed on California's list of banned weapons. To circumvent this, Intratec rebranded a variant of the TEC-9 as a 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. In 1993, the weapon was the subject of further controversy following its use in the 101 California Street shootings That same year, California amended the 1989 Roberti–Roos Assault Weapons Control Act (AWCA), effective January 2000, to ban handguns having features such as barrel shrouds. During the 1990s the TEC-9 also developed a reputation for its use by American street gangs and organized crime syndicates, who were attracted to the large capacity 32-round magazines and low cost of the firearm. The TEC-9 was produced from 1985 until 1994, when the model and TEC-DC9 variants were banned nationally in the United States, among the 19 firearms banned by name in the now-expired 1994 Federal Assault Weapons Ban (AWB). This ban forced Intratec to cease their manufacture, and forced them to introduce a newer model. The following year Intratec introduced the AB-10 ("AB" standing for "After Ban"), a TEC-9 Mini without a threaded muzzle/barrel shroud and sold with a smaller 10-round magazine instead of 20- or 32-round magazines. However, the AB-10 still accepted the larger capacity magazines of the pre-ban TEC-9 models, and were often acquired by users in place of the standard magazine. In 1999, the TEC-DC9 Mini was notoriously used by Dylan Klebold, one of the perpetrators of the Columbine High School massacre, ending with him using it to take his own life. The TEC-9 was also used in the 1990 drive-by shooting at Nashville, Tennessee West End Synagogue by Grand Wizard of the Ku Klux Klan Leonard William Armstrong. In 2001, the Supreme Court of California ruled that Intratec was not liable for the 1993 101 California Street attacks, and that same year Intratec was dissolved and production of the AB-10 model ceased. Although still found on the used firearms market and legal on the federal level since 2004, the TEC-9 and similar variants are banned, often by name, in several
