TEC-9

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.

History

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. 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".
