Dickinson LLC XX3DM18 12 Gauge 3" 6-Round Marine Finish Pump-Action Shotgun

The Dickinson LLC XX3DM18 12 Gauge 3" 6-Round Marine Finish Pump-Action Shotgun is purpose-built for law enforcement, military, and maritime security operations where corrosion resistance and reliable firepower are non-negotiable. The marine finish designation indicates a specialized coating designed to withstand saltwater, humidity, and harsh environmental exposure—critical for coastal defense, naval security, and wet-climate tactical deployments. This 12-gauge pump-action platform delivers the stopping power and magazine capacity demanded by professional operators who need a versatile, fast-cycling combat shotgun.

Built on the proven Breda/Dickinson receiver, the XX3DM18 features a 6-round tubular magazine capacity and accommodates both 2.75" and 3" shotshell ammunition, providing flexibility in load selection for different tactical scenarios. The pump-action mechanism ensures positive chambering, consistent reliability in rapid-fire sequences, and manual safety control—essential advantages in high-stress environments where mechanical simplicity trumps complexity. At 9.2 pounds with an overall length of 44.5 inches, the shotgun balances manageable recoil absorption with adequate velocity for effective shot patterns at combat distances. The marine finish protects the receiver and barrel against oxidation and salt-air degradation, extending service life in environments where standard blued finishes deteriorate rapidly.

Law enforcement agencies, military units, and professional security teams operating in coastal or corrosive environments benefit most from the XX3DM18's specialized finish and proven platform. The 6-round capacity and 18-inch barrel provide the tactical reach and ammunition availability needed for building clearance, vehicle interdiction, and perimeter defense without sacrificing mobility. Operators requiring a no-nonsense, marine-grade shotgun for sale will find the Dickinson XX3DM18 specifications well-suited to demanding duty cycles where finish degradation is a documented maintenance concern.
