Auto-9 gun from RoboCop

The Beretta 93R "Auto 9" is a heavily modified Beretta 93R that was originally built for the titular protagonist of the 1987 film RoboCop. The pistol is fitted with an extended casket-shaped barrel with a raised front sight and matching enlarged rear sight. While made specifically for RoboCop, it has been such a popular design that it has since been reused in numerous other forms of media, including the film and TV sequels and spin-offs to RoboCop.
