Bond Arms Derringer

The COP .357 Derringer is a compact, four‑shot, double‑action pocket pistol designed for concealed‑carry self‑defense. Conceived by the small‑bore firearms firm COP Inc., the weapon emphasizes maximum firepower in a minimal envelope, offering a .357 Magnum cartridge in a pistol barely larger than a traditional two‑shot derringer. Its primary market is civilian self‑defense and law‑enforcement backup, with a niche following among collectors who value its unusual four‑barrel layout. The design’s distinguishing features include a staggered‑column barrel cluster, a single trigger that cocks and releases all four hammers sequentially, and a robust stainless‑steel frame that tolerates the high pressures of .357 Magnum. The derringer’s reputation is mixed: praised for its stopping power and simplicity, but criticized for a heavy trigger pull and limited sighting options. Its unique four‑shot capacity in a pocket‑size package remains unmatched among modern derringers, making it a notable outlier in the compact pistol segment.

The Freedom Arms 22 Derringer was a precision-machined single-shot pistol chambered in .22 Long Rifle. It featured a stainless steel construction with a tip-up barrel and automatic ejection. The weapon was hand-fitted with tight tolerances for exceptional accuracy in a small package.
