The Mossberg 590 Retrograde brings classic pump-action reliability to modern defensive roles. Chambered in 12 guage with a 20" barrel and a 3" chamber, this retro-styled 590 offers an 8+1 capacity, rugged controls, and a build focused on real-world reliability for home defense, duty, or rugged field use. The 590 Retrograde keeps the proven mechanics that made the 590 line a staple for professionals-dual action bars, steel-to-steel lockup, and a smooth, positive pump stroke-while offering ergonomics and capacity that matter under stress. The 20" barrel balances maneuverability with patterning consistency, and the 8+1 magazine tube gives generous firepower without excessive length. If you want a no-nonsense pump shotgun that will run when it counts, this 590 fits the bill.
