Tacstar Slimline Sidesaddle Shotshell Holder for Mossberg 500/590

The Tacstar Slimline Sidesaddle Shotshell Holder for Mossberg 500/590 is a streamlined ammunition carrier that mounts directly to the receiver of your shotgun, positioning extra rounds exactly where tactical reloads demand them. Born from decades of law enforcement and military shotgun deployment, sidesaddle carriers eliminate the fumbling associated with traditional bandoliers or pouch systems. This Tacstar design specifically addresses shooter feedback for a low-profile reload system that doesn't obstruct optics, rail systems, or natural cheek weld on modern sporting and duty shotguns.

Tacstar's Slimline version emphasizes secure shell retention while enabling fast, intuitive shell removal under stress—a critical performance differentiator in force-on-force training and operational environments. The holder features integrated retention geometry that keeps 2" and 2-3/4" shotshell loads firmly seated until index finger or thumb strips them free for fast loading. The compact 7.5 x 1.5 x 8 inch profile minimizes weight addition (1.01 lbs fully loaded) and mounting footprint, preserving the Mossberg 500 and 590's inherent ergonomic advantages. Polymer construction resists corrosion and vibration-induced loosening without degrading durability in field conditions spanning temperature extremes and high round counts.

Duty shotgun operators, home-defense shooters, and 3-gun competitors benefit most from this carrier's rapid-access design and Mossberg 500/590 platform compatibility. Installation requires no gunsmithing—standard receiver-mounted installation maintains zero shift on existing sighting systems. The slimline profile proves especially valuable for shooters running electronic optics, bayonet lugs, or full-length rail systems where traditional sidesaddles create conflicts or obstruct sight pictures. Whether deploying your shotgun for training, sport, or duty use, this Tacstar holder delivers proven reliability and speed-focused ergonomics refined through real-world tactical requirements.
