Mossberg 590S: Tactical Versatility Meets Practical Design
The Mossberg 590S represents a significant advancement in pump-action shotgun design, offering shooters unprecedented flexibility in ammunition selection. This is not a gun that forces you into a single choice—it accepts and cycles three different shell lengths seamlessly.
Chamber and Ammunition Flexibility
The 590S chambers 3 inches and cycles:
- 1.75-inch short shells (13+1 capacity)
- 2.75-inch standard shells (8+1 capacity)

You may load any combination of these lengths simultaneously. This flexibility allows you to select the appropriate load for your specific shooting need—whether that's sport shooting, home defense, or hunting—without changing shotguns.
