The Mossberg 500 and 590 Series shotguns are among the most trusted and battle-tested pump-action shotguns in the world. Celebrated for their rugged reliability, versatility, and affordability, these American-made firearms have served hunters, homeowners, and military units for over 60 years. Whether for home defense, police duty, or field use, the Mossberg 500 and its military-grade 590 counterpart deliver unmatched performance and durability.
Introduced in 1961, the Mossberg 500 quickly earned a reputation as a reliable and affordable pump-action shotgun. Designed by Carl Benson, the Model 500 series was built around a simple but strong **dual action bar** system and an **aluminum alloy receiver**, combining lightweight handling with long-lasting durability. Over time, the platform expanded into multiple configurations — from the field-ready 500 to the heavy-duty **590 and 590A1** models trusted by the U.S. military and law enforcement agencies worldwide.

One of the Mossberg’s signature advantages is its **tang-mounted safety**, located on top of the receiver. This design is truly ambidextrous and easy to operate — even when wearing gloves or using optics — making it a favorite among left-handed shooters.
The Mossberg 500/590 features dual extractors and twin action bars that ensure smooth cycling and positive ejection, even under harsh conditions. These design choices are why Mossberg shotguns are known to “run dirty” with exceptional reliability.
Tool-free takedown allows the shotgun to be disassembled in seconds for cleaning or swapping barrels. From deer slug barrels to breacher setups, the Mossberg’s **modular platform** can adapt to hunting, home defense, or tactical use in minutes.
The **anodized aluminum receiver** keeps the shotgun’s weight manageable while still providing strength and corrosion resistance. Unlike steel-framed competitors, the Mossberg balances beautifully, especially in field configurations.
The Mossberg 590A1 remains one of the few shotguns to pass rigorous U.S. military endurance and reliability tests. It’s been used extensively in Iraq, Afghanistan, and by law enforcement across the country, proving its status as one of the toughest pump-action designs ever made.
While shotguns are measured by pattern rather than precision, the Mossberg’s **tight manufacturing tolerances and solid barrel lockup** result in consistent point-of-impact. Slug-barreled and ghost-ring-sighted versions can deliver excellent accuracy at 50–100 yards, ideal for deer hunting or defensive applications.
The 500/590’s ergonomics and recoil-absorbing stock options make shooting comfortable, even with heavy loads. Lightweight construction keeps fatigue low, while the pump action cycles smoothly under any condition.
Few shotguns match the Mossberg’s track record for reliability. It has earned a reputation for **functioning under mud, rain, and sand**, making it the go-to platform for shooters who demand performance in the harshest environments.
The Mossberg’s simple design makes it easy to maintain. Disassemble by removing the magazine cap and barrel, then slide out the bolt and trigger assembly for cleaning. Wipe down the action bars, magazine tube, and receiver interior, and apply a light oil film to moving parts. Thanks to its corrosion-resistant finish options, the shotgun is highly tolerant of weather and storage conditions.
The Mossberg 500 and 590 Series represent the pinnacle of American pump-action shotgun design — rugged, adaptable, and battle-proven. Their ambidextrous controls, field-ready reliability, and military-tested toughness make them ideal for nearly any role, from hunting to home defense. Whether you choose the classic 500 or the duty-grade 590A1, you’ll own a shotgun built to perform for a lifetime — and beyond.
