Excellent choice. I love my 590A1. For me, the main advantage of a pistol grip stock is one hand control of the firearm when the gun is not shouldered. With the 20" heavy barrel you'll likely find it a bit un-wieldy one handed.A standard stock is notably better for bashing zombie skulls. I've got a TacStar sidesaddle shell holder and it functions flawlessly. Never hand any shells wiggle out, even after extended blasting sessions. Just don't over tighten the mounting screws, use a bit of blue loctite.
Oh yeah.....and get youself something pointy for the end of it
