The Mossberg 590S 12 gauge pump action shotgun delivers exceptional shell flexibility by cycling 1.75, 2.75, or 3 shells—load a single length for dedicated applications or mix any combination of these three gauges in the same magazine tube.
Built on proven Mossberg pump-action engineering, the 590S incorporates dual extractors, twin action bars, positive steel-to-steel lockup, and an anti-jam elevator to ensure dependable cycling. The top-mounted ambidextrous safety accommodates shooters of any preference, while the matte blue metal finish provides a durable working surface. Additional details include a magazine clean-out tube with cap and a logo-engraved receiver.
The 590S gives you the freedom to select the right shotshell length for your specific shooting needs or run mixed loads without changing firearms.
