The Intratec TEC-9 is a blowback-operated line of semi-automatic and burst pistols. They were developed by Intratec, an American subsidiary of the Swedish firearms manufacturer Interdynamic AB. Introduced in 1984, the TEC-9 was made of inexpensive molded polymers and a mixture of stamped and milled steel parts. The simple design of the gun 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. Most notably it was used during the 101 California Street shooting and the Columbine High School massacre. However, it was a commercial success, with over 250,000 being sold.
