I did not expect this. Remington will be selling a new pump-action shotgun next year (2009) called the Model 887 NitroMag. The design is not based on the popular 870 and will not replace it.

I am guessing by the name “Nitro Mag” that it will chamber 3 1/2″ 12 gauge shells. According to Adam the barrel and other parts are coated in a polymer to prevent rust. Air guns barrels are often coated with plastic, although I think this is also done to add strength to the thin air gun barrels..

It looks like it will compete head-to-head with the Mossberg 835 Ulti-Mag which was designed specifically for firing 3 1/2″ magnum shells.

UPDATE:

Two models will be available. The 887 Nitro Mag Synthetic and the 887 Nitro Mag Waterfowl

Remington redefines pump shotgun technology with the 12 gauge Model 887 Nitro Mag. The most durable and reliable shotgun ever built; it has minimal external surfaces to rust. Our exclusive ArmorLokt™ construction process seals the receiver and barrel in a vault of weather-impervious polymer material. Its overmolded surface is built to withstand abrasion and hard-core hunting abuse whether that’s barbed wire, gnarly thorns or the bottom of a Jon boat. And when it’s time for action, our revolutionary new SuperCell™ Recoil Pad so effectively reduces rearward force that it makes a magnum 12 gauge feel like a light field load. The Model 887 Nitro Mag is our softest-shooting pump gun ever. That means enhanced confidence on the first shot and smoother, faster follow-ups.

Because the Model 887 Nitro Mag’s design is inspired by the strength and dependability of our Model 870, you can count on it to cycle flawlessly and stand up to abuse like no other. Similar to the Model 870, its receiver is manufactured from solid steel and the barrel is hammer-forged. Our ArmorLokt process packages it all under a weather-impermeable outer shell. Twin steel action bars ensure smooth, positive chambering and ejection for the long haul. And the sleek receiver design, awesome balance and natural pointing characteristics spell trouble for any bird within reach of its 12-gauge 3 ½-inch Super Magnum capability. The extremely rugged synthetic stock and fore-end are ergonomically contoured to offer a positive grip and comfortable handling while the built-in swivel studs insure a solid attachment for adding slings.
