Intratec AB-10

The AB-10 is a blowback-operated, semi auto pistol. It was designed by George Kellgren and made in Miami, Florida from 1994 to 2001 when Intratec went out of the business. It is based on the Tec-9 which was made from 1985 to 1994 when it was banned by the now-expired Federal Assault Weapons Ban (AWB). The Tec-9 was banned and production stopped so Intratec made new variant called AB-10 without a threaded muzzle/barrel shroud and shipped with 10-round magazine. However, it accepted the standard 20 or 32-round capacity magazines of the pre-ban models. The AB-10 have a threaded upper receiver tube at the rear and a 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. It fires from closed bolt, and have a separate firing pin and a massive striker, which interoperates with the sear. The receivers is made from steel tube, the frames are made from polymer, integral with pistol grip and magazine housing ahead of the trigger guard.
