It doesn't show it on Remingtonle.com (http://www.remingtonle.com/shotgun/870p.htm), and I can't seem to find it anywhere.

This probably isn't much help, but gunfinder.net (http://www.gunfinder.net/getprice/index_longguns.shtml) has a couple wood models on their site listed at $484 for the 18" Blue and $499 for the 20" Parkerized. Their other MSRPs seem to be on track with what Remington publishes, so I suppose they are correct. I have never seen them advertise any of the synthetic or extended mag models though and don't know offhand where to find MSRPs on them.

I'm not sure that Remington has a standard MSRP on their LE weapons. Many departments buy these guns in multiples, and the size of the order often determines the price they'll get. If an individual officer orders one with a departmental letterhead, he'll probably get a different price. It's not like the commercial market, where a wholesaler or distributor gets a price on a large batch and then marks them up accordingly.
