I traded my 590 for an 870 tactical earlier today, put a few boxes of shells through it to confirm function and now it's time to put a collapsible pistol grip stock on it. Being able to easily adjust the length, add a cheek riser, and just have something different from my other shotguns will be cool. I'm looking at the Tacstar kit, Archangel stock and maybe a Mesa Tactical LEO adapter. The factory stock on the 870 is sooooooo much better than the Magpul stock I had on the 590. Just my opinion but I HATE that stock.
