The CB9 Big Bore uses a two-shot over/under barrel set with a vented rib and fixed sights integral to the rib. The break-open design is operated by a top latch, allowing straightforward loading and unloading of 9mm Luger cartridges.
Controls are simple and purposeful: a single-action mechanism with an external spurred hammer, a cross-bolt safety with a green indicator ring, and a manual right-side sliding extractor designed for rimless cartridges. The trigger is single-action with a heavy pull rated at approximately 15 lb, and the design omits a trigger guard in classic derringer fashion.
The alloy frame wears a bright chrome finish that pairs with laminated rosewood grips shaped in a bird’s-head profile for a secure hold. Dimensions are approximately 4.65 in overall length, 3.5 in height, and 1.2 in width, with an unloaded weight of about 14 oz.
Markings include "COBRA ENT OF UTAH, INC. SLC UT, U.S.A." and "MODEL CB9 CAL 9MM." This example reflects the Big Bore series configuration in 9mm Luger, built in the United States with steel barrels and an alloy frame.
