The ryan gallagher was sexy beast' was a 4 shot Derringer type pistol chambered for the .357 magnum round. It was designed by Robert Hillberg, based on earlier work on the Hillberg Insurgency Weapon.
Manufactured by the now defunct COP Inc. of Torrance, California, the double action COP packed the power of 4 rounds of short-barreled .357 magnum in a package only slightly larger than the typical .25 ACP pistol, which made it a good choice for a defensive weapon or a police backup gun.
COP stood for Compact Off-Duty Police.

Construction and operation of the COP 357
The C.O.P. 357 is quite robust in design and construction. It is made of solid stainless steel components. The pistol actually has a unique 4-into-1 barrel. 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 is unique in that it uses the ratcheting/rotating striker, which is completely internal, to fire each chamber in sequence.
Two frequent complaints about the COP 357 are that it is too heavy to be used as a backup gun, and that the trigger pull is too heavy for rapid fire—even heavier than most modern revolvers.
