Overview

The Rossi M4122B is a single-shot, break-open shotgun originally manufactured for law enforcement agencies. The “police trade-in” designation means these firearms were carried and used, but not subjected to high round counts. The action is simple and robust: open the lever, insert a single .410 shell, close the barrel, and fire. The external hammer must be manually cocked before each shot, providing an inherent safety feature. These shotguns feature a blued steel barrel and receiver, with a hardwood stock and forend. Barrel length is typically 18.5 inches, making it maneuverable in tight spaces. The Rossi M4122B 410 Bore Police Trade-In Break Open Shotgun is a fixed-choke model, usually modified or full, depending on the specific production run. Do not expect a pristine finish; these are working firearms with cosmetic imperfections.

Features & Specs

• Action: Single-shot, break-open with manual external hammer. The barrel tilts down for loading and unloading after pressing the release lever. No magazine, no complex internal mechanisms.
• Caliber: .410 Bore (2.5-inch and 3-inch shells compatible). Accepts standard .410 shot shells, slugs, and buckshot. Not rated for 3-inch magnums unless verified on barrel stamp.
• Barrel: 18.5-inch blued steel barrel with fixed choke. The barrel is not threaded for chokes. Bore condition is generally good with minor fouling; heavy pitting is uncommon but possible.
• Stock: Hardwood stock and forend with a satin finish. Expect dings, scratches, and worn finish. The stock may have a slight oil or solvent smell from previous storage. Not a presentation-grade wood.
• Weight: Approximately 5.5 pounds unloaded. Light enough for carry, but provides enough mass to manage .410 recoil effectively.
• Safety: Manual hammer half-cock notch serves as the primary safety. No crossbolt or tang safety. The hammer must be manually lowered to half-cock for safe carry.
• Sights: Fixed front bead sight. No rear sight. The bead is typically brass or white plastic. Some trade-in models may have a missing or damaged bead.
• Overall Length: Approximately 35 inches. Compact and easy to store in a vehicle scabbard or closet.
