Makes firing the shockwave slightly less awkward - SB Tactical 590-SBM4 Stabilizing Brace Kit for Mossberg 590 Shockwave

Installed on my 590 Shockwave. Installation was a snap, and fit and finish is fine. Used as an arm brace it really does give you more control over the shockwave, and the pistol grip feels much more secure in your hand than the raptor grip. The recoil is still pretty strong with full size shells, but I feel more in control with this setup. With mini-shells the recoil is barely noticeable. I will say that if you ever do accidentally bring the brace up to your shoulder when firing, you'll find that the sharp, hard rear edges of the brace can definitely get your attention!
