Blackhawk Knoxx stock is the way to go. The recoil reducing one is well worth the money and you can add on the power pak for it and you will get 5 rounds of storage and other stuff. I have one and it works great.
As for other upgrades the only other thing I can suggest, because it's a home defence gun, is getting a light for it. I just got the Streamlight TLR-1s and it is awesome and very bright.
