Mossberg 590S 12 Gauge, 18.5 Inch Barrel, HS407K

Description

The Mossberg 590S is built for home defense and close-quarters work where a compact, fast-handling pump gun is the right tool. The Magpul furniture — stock and forend — gives the shooter a more secure grip surface and a sturdier feel than standard polymer, and the gray finish runs consistently across both the furniture and the receiver, keeping the package visually cohesive rather than looking like assembled parts from different guns.

What separates the 590S from earlier 590 variants is its ability to cycle 1¾-inch minishells alongside standard 2¾-inch and 3-inch loads without modification. That flexibility matters in practice: minishells reduce felt recoil and increase round count, while standard buckshot and slug loads remain fully compatible when the situation calls for them. The shooter does not have to choose one loading regime and commit to it.

A 9+1 capacity with standard shells is already substantial for a shotgun in this class, and the tradeoff for that capacity in an 18.5-inch barrel is a gun that stays maneuverable in tight spaces without giving up meaningful ballistic performance at defensive distances. The included Holosun HS407K red dot mounts to the receiver’s optic-ready cut, putting a parallax-tolerant, both-eyes-open sight picture on a platform that traditionally relies on a front bead alone. That front bead remains as a backup reference point. The combination suits a shooter who wants a dedicated optic without the added steps of sourcing a compatible mount separately.
