Mossberg sent shockwaves through the firearms industry when they first released their lineup of Shockwave firearms. They have continued to innovate and improve the design and are now proud to present the Mossberg 590S Shockwave pump action firearm. This compact but powerful shorty firearm boasts flexibility that most other shotguns just don't have. With its 3" chamber and redesigned elevator, the 590S Shockwave allows the user to load their choice of shell length (1.75", 2.75", and 3") and load them in whatever combination and order they desire! If you prefer to use only 3" shells, you've got a 4+1 capacity. If you prefer 2.75" shells, it holds 5+1. If you prefer to maximize the 590S's capacity, it can hold 8+1 of the 1.75" "mini-shells". Or if you prefer to mix things up, you can load a combination of those shells in the order you prefer! The 590S Shockwave includes all the best features from the 590 lineup that make it such a reliable firearm. These include non-binding twin action bars, an anti-jam elevator, positive steel to steel lockup, dual extractors, and a top-mounted manual safety. The 590S Shockwave utilizes a 14.375" barrel and a Raptor bird's head style grip to maintain a small size, but still packs a powerful 12 gauge punch. A corncob style forend with a hand strap allows you to maintain control of this firearm while firing and assists you with pumping the action. The Mossberg 590S Shockwave features big improvements over the original Shockwave design and makes a great defensive firearm and a fun range toy!
