Our Assessment: The COP Inc. SS-1, known as the Compact Off-Duty Police pistol, was introduced in the late 1970s as a distinctly unconventional approach to personal defense firearms. Designed around a four-barrel, break action system, the SS-1 allowed four shots of .357 Magnum or .38 Special to be fired in succession from a compact, all-stainless platform. Its internal striker-fired mechanism and rotating firing system eliminated the need for a traditional revolver cylinder, resulting in a solid, block-like construction that emphasized durability and simplicity. At a time when compact defensive handguns were evolving rapidly, the COP pistol stood apart with its unique engineering and substantial build, offering a different solution for close-range defensive use. This example remains in excellent overall condition, retaining approximately 99 percent of its original satin stainless finish with only faint handling marks and light hairline scratches visible. The bores are bright with sharp rifling and only minor fouling present, reflecting limited use. The two-piece checkered wood grips are in excellent condition, showing little to no wear while maintaining crisp checkering and a clean appearance. The fixed half-moon front sight and notch rear sight integrated into the release latch provide a simple and effective sighting arrangement consistent with the pistol’s intended role. The included original case and paperwork further enhance the completeness and presentation of this distinctive firearm.
The COP SS-1 remains one of the more unusual and recognizable defensive handgun designs of its era, combining multiple barrels and a compact footprint in a rugged stainless steel package. Its distinctive configuration, strong condition, and complete accessories make it a notable example of late 20th century firearm innovation. As a mechanical departure from conventional revolvers and semi-automatics, it continues to stand out as a unique interpretation of multi-shot defensive capability. -R.E.
