Break-open with extractors for reloading, double-action trigger with rotating firing pin selector. The COP .357 is a 4-shot Derringer -type pistol chambered for .357 Magnum. 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 an option for a defensive weapon or a police backup gun.

Construction and operation of the COP .357
Drawing from US patent 4,407,085, covering the COP Derringer operating mechanism
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.
