Lookin for a house-hold scattergun

So, what to get? I'd like to spend less than $800 for...

• 12 ga
• slide action
• short pull
• low recoiling
• weapon-light accepting
• non-beaded combat sights
• 18" barrel

With plenty of manufacturers to consider...

• Remington
• Mossberg
• Benelli
  
• FNH
  

I'd love to get a Vang Comp custom, but I think that'd push me over the price limit I was set on.

I gotta say that a lot of tactical options look great, but I'm not SWAT and I need something that my wife can use too. I am hopeful that she can handle a 12 ga, but realize that I might have to consider a 20 ga down the line if she doesn't like the recoil of the larger guage.

So far, I like the Remington 870 Tactical with the SpecOps collapsible stock and the Mossberg 590A1 with ghost ring sights.

I don't believe in "clearning the house"... I just want something for holding out in the bedroom until the cops can come check things out.
