Thanks for the tips, guys. I've always liked Remington, I've had a 700 CDL chambered in 7mm Rem Mag for a few years now, and their customer support is top notch.
I was wondering if anyone has ever heard of/used this shotgun, the Remington 887?

It seems to be based off of the 870, and it's almost $50 less expensive than an 870 of similar specifications.
I wouldn't bother with any of the factory tactical shotguns. Like I just pointed out, you can buy a hunting/sport shotgun for much, much less $$$ (I saw brand new 870 Expresses for $299 at a major retailer last month) then also buy whatever tactical (or tacticool) accessories you want (short barrel, mag extension, compensator, picatinny rail, pistol grip, speedloader, sights, etc...) and save a lot of money. Plus then you still have the option of swapping back to the long barrel and other stock parts if you ever want to go hunting or bust some clays.
As for the 887, it's a relatively new model and I have no firsthand experience with it. I'll just say this, the 870 has been around for decades and has a proven track record in sporting/hunting, law enforcement, home defense and military applications. With an 870 you
KNOW you're getting a super reliable proven design, the 887 is still a question mark and it has been getting "mixed" reviews so far.
