The COP 357 is an extremely rare pistol that is no longer in production. Made famous in the movie "Blade Runner" and seen in such movies as "Bad Boys", "The Matrix Reloaded",and most recently "21 Jump Street" the COP would be a welcomed piece to any collectors collection, Or just for anyone looking for something rare, beautiful, and different. Easy to fire and easy on the eyes this rare pistol has 4 barrels which fire 357 magnums or .38 specials. The COP 357 is a 4 shot Derringer type pistol chambered for the powerful .357 Magnum round. It was designed by Robert Hillberg, based on his earlier work on the Hillberg Insurgency Weapon. It was manufactured by the now defunct COP Inc. of 3040 West Lomita Blvd., Torrance, California (COP stood for Compact Off-Duty Police). The double action weapon is about twice as wide, and substantially heavier than the typical .25 automatic pistol, though its relatively compact size and powerful cartridge made it a good choice for a defensive weapon or a police backup gun. The COP 357 is quite robust in design and construction. It is made of solid stainless steel components. Cartridges are loaded into the four separate chambers by sliding a latch that "pops-up" the barrel for loading purposes, similar to top-break shotguns. Each of the four chambers has its own dedicated firing pin. It uses an internal hammer, which is activated by depressing the trigger to hit a ratcheting/rotating striker that in turn strikes one firing pin at a time. Older "pepperboxes" also used multiple barrels, but the barrels were the part that rotated. The COP 357 operates similarly to the Sharps rimfire pepperbox of the 1850s, in that it uses the ratcheting/rotating striker, which is completely internal, to fire each chamber in sequence.
