Mechanics: The action functions correctly. The pistol has four barrels and four firing pins which are triggered sequentially. The barrel set has an extractor star. The trigger pull is “staple-gun”-like, stacking through a long pull with a sharp break at the end. We did not fire this handgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Our Assessment: 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. This COP is in Very Good-Fine condition, showing wear consistent with normal handling and operation and comes with a COP jewelry case. The bores are mostly bright with sharp rifling and no erosion though there is some stubborn fouling and leading. The design was patented in 1983 and production was moved to American Derringer in 1990, making this a rare beauty, made by its original company. While the design didn’t take off commercially, the COP derringers are quite collectible today, especially one in high condition with its box. Please see our pictures and good luck!
