TacStar SideSaddle Shotshell Carrier - Mossberg .500 .590 DA

The TacStar SideSaddle Shotshell Carrier for Mossberg .500 .590 DA mounts directly to the receiver of your shotgun, providing immediate access to six additional rounds without blocking the sight picture. Manufactured by Pachmayr Ltd's Tacstar division, this carrier addresses a fundamental operational need: maintaining firepower on target while carrying reload ammunition in the fastest, most accessible position possible.

The side-mounted design keeps both hands free for weapon manipulation and allows shooters to maintain sight alignment during reload transitions. At 0.54 lbs with compact dimensions of 5.85 x 2.25 x 8.9 inches, the carrier adds minimal weight and profile while maintaining the structural integrity needed for reliable operation in dynamic environments. The form factor works specifically with Mossberg .500 and .590 DA receivers, ensuring a secure, rattle-free fit that withstands the recoil impulse of full-power shotgun loads without shifting during extended shooting sessions.

This accessory is purpose-built for patrol officers, tactical operators, and serious shotgun competitors who need rapid magazine replenishment during live-fire drills or emergency responses. Law enforcement professionals working with pump-action shotguns for entry, barricade work, or less-lethal applications benefit from the intuitive positioning—rounds remain within arm's reach without requiring a break in target focus or weapon index. Home defenders and civilian shooters who train with duty-length shotguns will appreciate the streamlined reload workflow this carrier enables.

Side-saddle carriers represent the fastest stationary reload method available for pump and semi-auto shotguns, eliminating reach to belt carriers or off-body sources. The SideSaddle design from Tacstar has been proven in field service across multiple decades, making it a category standard among operators who prioritize speed and reliability over novelty.
