Single-shot shotguns remain a practical choice for collectors, trainers, and shooters seeking a simple, reliable platform with minimal maintenance and predictable handling. For buyers interested in a compact 20-gauge option that blends heritage styling with straightforward function, this model is worth close inspection.

COMPANHIA BRASILEIRA DE CARTUCHOS SB is a single-shot 20-gauge shotgun with a 2 3/4-inch chamber and a full choke barrel.

Design and key features

The COMPANHIA BRASILEIRA DE CARTUCHOS SB is notable for its classic hardwood stock and decorative scroll engraving on the receiver, a look that appeals to both collectors and shooters who prefer traditional aesthetics. Built in Brazil and imported into the U.S. by firms such as Firearms Import and Export Corp., this single-shot keeps the platform simple: a manual-break action, a full choke barrel, and a chamber sized for 2 3/4-inch shells.

Barrel, chamber, and choke explained

The 20-gauge chamber and full choke combination produces a tighter pattern at moderate ranges compared with open-choke options. That makes it suitable for small game, upland birds, and controlled range use. The 2 3/4-inch chamber limits you to standard-length shells, which helps ensure reliable extraction and feeding in this single-shot configuration.

Handling, recoil, and applications

As a 20-gauge, the SB offers reduced recoil compared with larger gauges, making it an excellent choice for novice shooters, training sessions, or those who prioritize a lighter shooting experience. Its single-shot action encourages deliberate, accurate shooting—useful for hunting scenarios where one well-placed shot is desired, or for educational settings teaching fundamentals of stance and trigger control.

Condition notes and maintenance

Many examples of this model come as used firearms and commonly show wear: light scratches on wood, surface discoloration on metal, and occasional minor pitting or rust. The action, however, frequently remains functional. Inspect for breech face integrity, smooth hinge operation, and secure stock-to-receiver fit. Regular cleaning of the bore and light rust treatment will extend service life.

At a price of $199.99, the COMPANHIA BRASILEIRA DE CARTUCHOS SB represents an affordable entry point into a traditional single-shot 20-gauge. Whether adding to a collection or selecting a straightforward field gun, evaluate condition carefully and confirm chambering for 2 3/4-inch shells.
