Check out the Wilson/Scattergun Tech K-9 model if you want something really designed for gunfighting. I don't mean nessesarily to send yours in to get it converted, but create your own (that said, the action work is supposed to be incredible, as in they cycle faster than a Benelli)version with: Track Lock Ghost Rings (MMC might be easier) front post with tritium, extended mag, cut to 18", special metal-backed side saddle, synthetic stock, buttpad undercut for quick shouldering, flourescent green mag tube follower, enormous cocking handle and jumbo head safety, parkerized, 3 way sling (front attachment point industrial strength, no puny swivels here),...I'm forgetting a lot more. I agree with mgdavis, but know how it is when you just have to tweak with something. That is my favorite auto shotgun though (along with Saiga 12 Folder) the K-9 of above description. All in all it is the Ed Brown, Les Baer of Shotguns and doesn't cost any more than a stock .308 battle rifle. I love that shotgun. I listed off some features if you want to accessorize, but I have to say, not being into custom work at all, I hope to get one someday, and this action/reliability job makes a world of difference; an 11-87 is great, imagine having it improved functionally even more. I think they still will perform the job on customer supplied shotgun, but not sure. From what I have read this is money well spent.
And maybe a Patternmaster choke also would make a nice add-on, super tight groups at long distances.
Just sopme thoughts. But I love the idea of wood on your HD/Duty gun. Nice, old school flair. I'd say definately add an extended mag, but after that youre good to go. I just brought up the K-9 stuff because it's such an awesome weapon, like a Ed Brown 1911 that started as a Springfield Mil-Spec. The best in the world can be had at somewhat affordable prices as far as an auto combat shotgun. Same cannot be said of a pistol or rifle. So there's that appeal to it. It's just a great package, an old American Survival Guide article on it showed the author holding it sideways above his shoulder level, and not only did it function in such a odd position, he had something like 5 hulls in the air at once. That's a shotgun I'd be proud to have protect my home and family.
Best of luck with your baby whatever you do with her.
Just something to keep in mind if you ever want to have some custom work done. I remember a huge chunk of the price was gone if you supply your own Remmy. They have to be in exc. condition, however.
Might as well have your first line of defense be the Cadillac in your collection
