This compact firearm, manufactured by Cobra Enterprises, is a two-shot handgun chambered for the .38 Special cartridge. The “big bore” designation likely refers to the use of .38 Special, a relatively powerful round for a derringer, compared to smaller calibers sometimes used in these types of firearms. Derringers are generally characterized by their small size, intended for concealed carry and close-range self-defense.
These handguns occupy a niche market, appealing to individuals seeking a deeply concealable firearm for personal protection. The increased power offered by the .38 Special cartridge provides a greater stopping potential compared to smaller calibers, while the compact size makes it easier to conceal and carry discreetly. Historically, derringers have been associated with backup firearms or close-quarters defense, often carried as a last resort. Modern advancements in design and manufacturing have led to improved reliability and safety features in these compact handguns.
