High security is fine; high maintenance isn't. Enter the Mossberg® 500® and 590® Persuader® shotguns -- the pump-action shotguns you can count on for your security needs. They have the credentials and track record to prove it. In their commercial form, the Persuaders are virtual duplicates of the proven Mossberg® military 500® and 590® models -- the only pump-action shotguns ever to pass all stringent U. S. Military Mil-Spec 3443 standards. Use the 500® Persuader® at home and the Mariner® on the water – these guns are dependable and economical. Especially when you don't have to cover the added expense of chew toys. Available in a full range of popular models. Persuader® shotguns are available in both 18-1/2” and 20” barrel lengths, traditional blued or non-glare matte finishes, a four-shell capacity Speedfeed® stock and Ghost Ring® sights for quick target acquisition. Available in .410 bore, 20- and 12-gauge models, every Mossberg® Special Purpose Shotgun features a host of proven Mossberg® features like an anti-jam elevator, dual extractors for reliable feeding, and positive shot shell extraction and ejection. Rugged black synthetic stocks and drilled and tapped receivers (20 and 12-gauge only) for trouble-free scope base and optics installation make this an easy gun to rely on.
