"Designed for easy user-installation, the Knoxx Industries Sidewinder™ 10-round drum magazine system is perfect for law enforcement, home defense and competitive sporting applications. Also available with a 6-round box magazine, the Knoxx system makes reloading as simple as pushing the magazine release button and swapping magazines. Changing back and forth between buckshot, slug or less-lethal ammunition can be done quickly and positively. This unique system, available for most *Mossberg pump shotguns, is easily installed by simply removing the shotgun barrel and forend, unscrewing the factory magazine tube and replacing it with the Sidewinder assembly and forend. Once the barrel is reinstalled, the gun is ready for use. The magazine is ambidextrous and can be loaded with the offset drum on either the left or right side. The drum magazine slips easily into the magazine well and racking the slide delivers the first of ten 12-gauge shells into the chamber. Empty magazines drop free with the push of a button, allowing for a quick 10-round reload in just seconds. No permanent changes are made to the shotgun. The Sidewinder is ideal for SWAT or Special Team entry shotguns, less-than-lethal applications and for IDPA Three Gun Match competitors. Anywhere extended capacity and quick reloads are required, the Sidewinder is the perfect solution. Teamed up with the Knoxx COPstock recoil-reducing folding stock and a short barrel, the Sidewinder-equipped shotgun can be the ultimate entry or defense weapon. The Knoxx Sidewinder for Mossberg is available as a complete kit with either a 10-round drum or 6-round box magazine. Both magazines accept 2-3/4 and 3-inch shells. Drum and box magazines are also available separately. Suggested retail kit pricing is $189.95 with one drum magazine. Additional drums will be available at $89.95 each, with the 6-round box magazines at $49.95. Special pricing for law enforcement agencies and officers is available. Distributor and Dealer inquiries are invited. See our News page for availability. Call toll-free to 877-GO-KNOXX (877-465-6699). Order now as demand is skyrocketing" I think it sounds pretty cool.
