Pistol - 9x19mm NATO - USA/Sweden - Semi-Automatic - Based on the open-bolt Interdynamics KG9 SMG, the TEC-9 is merely a closed bolt pistol. It's popularity stems from: 1) its low price, and 2) the mistakened impression that it can easily be converted to full-auto (due to over-exposure in films and TV). It is often seen in the hands of wanna-be gang bangers. Thankfully for police, the reliability and accuracy of this weapon are nil.
