Unique to the Shockwave platform, and providing its novel moniker, is the Shockwave Technologies Raptor® pistol grip. This well‐designed pistol grip features an enhanced textured finish and has a “bird’s head” shaped‐profile, allowing for maximum control while minimizing felt recoil. The grip is constructed of durable, glass‐filled polymer with non‐reflective, black finish and has an overall length of 5.25 inches. Completing the furniture package for the 590M Shockwave is the cob‐styled, tactical forend which is strapped for greater control and smoother operation.

At the core of the 590M Shockwave are the magazine’s integral stabilizing ribs which engage the magazine directly to notches machined into the receiver, ensuring a positive lock‐up. The all‐steel, heated‐treated magazine release button and housing are optimally positioned in front of the trigger guard for convenient, ambidextrous access for unloading and reloading. The location of the mag release does not interfere with cycling of the action. The well‐executed design allows for proper balance with a full‐magazine located at the center of gravity point.

As a first for mag‐fed shotguns, the 590M design features a patented double‐stack magazine constructed with hardened‐steel feed lips, over‐molded steel shell ramps and an anti‐cant, rounded follower to ensure reliable feeding. Additional features include an easy‐grip, molded external shell; proprietary self‐lubricating polymer magazine body; heavy‐duty ASTM‐A‐228 music‐wire magazine spring for prolonged service life; removable floor plate for ease of cleaning; and durable black oxide finish on the steel components. This proprietary double‐stack magazine design provides greater capacity in less magazine length versus competitor’s single stack magazines.

The 590M Shockwave features an overall length of 27.5 inches, recoil‐taming pistol grip (not designed to be shoulder-mounted), compact 15‐inch barrel length and the convenience of magazine‐feeding.
