The Mossberg 590M 12 Gauge Shotgun: Unmatched Versatility and Reliability for Modern Demands

When it comes to selecting a firearm for critical applications like home defense, tactical operations, or competitive shooting, reliability, capacity, and ease of use are paramount. The Mossberg 590M shotgun, available at DEGuns, stands out as a revolutionary answer to these evolving needs. Building upon the legendary Mossberg 590 pump-action platform, the 590M introduces the groundbreaking convenience of a detachable, magazine-fed system, transforming how users interact with their shotgun in high-stakes scenarios.

What Makes the Mossberg 590M a Game-Changer?

The Mossberg 590M is not just another shotgun; it represents a significant leap forward in pump-action design. By integrating a robust magazine-fed system into the trusted 590 architecture, Mossberg has engineered a shotgun that offers unparalleled advantages for those who demand quick reloads, variable ammunition types, and higher capacities. Whether you're a homeowner seeking the ultimate in self-defense preparedness, a tactical professional requiring rapid adaptability, or a competitive shooter looking for an edge, the 590M series provides a robust, dependable solution designed to excel under pressure.

Why Choose a Magazine-Fed Shotgun? Exploring the Core Benefits

Many users often ask, "What are the benefits of a magazine-fed shotgun compared to a traditional tube-fed one?" The Mossberg 590M brilliantly answers this question by showcasing several practical advantages:

• Faster Reloading and Unloading: This is perhaps the most significant benefit. Instead of laboriously feeding individual shells into a tube, a fresh, pre-loaded magazine can be inserted in seconds, dramatically reducing downtime during critical situations or competition stages. Unloading is equally swift and safe, simply requiring the magazine to be dropped.
• Increased Capacity without Added Length: Traditional shotguns achieve higher capacity by extending the magazine tube, often beyond the barrel, which can make the firearm cumbersome and difficult to maneuver in close quarters. The 590M achieves an impressive 11-round capacity (with the standard magazine) while maintaining a compact 18.5-inch barrel length, ensuring superior handling.
• Quick and Easy Transitioning Between Loads: Imagine a scenario where you need to switch from buckshot to slugs, or from less-lethal rounds to birdshot, instantly. With the 590M, this is as simple as dropping one magazine and inserting another pre-loaded with your desired ammunition type. This versatility is invaluable for law enforcement, tactical training, and even recreational shooting where different targets require different loads.
• Enhanced Balance and Ergonomics: Full magazines naturally position the center of gravity closer to the shooter's hand, directly beneath the action. This centralizes the shotgun's weight, making the Mossberg 590M surprisingly easy to balance. This improved balance translates into quicker target acquisition, reduced shooter fatigue, and enhanced accuracy, particularly during rapid fire or extended use.
• Reduced Shell Deformation: Unlike tube-fed systems where shells are constantly under spring pressure and can sometimes experience deformation over long periods, shells stored in detachable box magazines maintain their integrity, ensuring more reliable feeding.

A Deep Dive into the Mossberg 590M's Robust Features

The Mossberg 590M isn't just about its innovative magazine system; it inherits a legacy of rugged durability and proven performance from the Mossberg 590 platform. Users consistently ask, "What features make Mossberg shotguns so reliable?" The answers lie in the meticulous engineering and time-tested components:

• The Legendary Mossberg 590 Foundation: At its core, the 590M is built on the same rock-solid Mossberg 590 architecture that has been the choice of military, law enforcement, and tactical users worldwide for decades. This heritage means you're investing in a design proven over time for its dependability in the harshest environments.
• Unique Stabilizing Ribs and Sure Lock-Up: A key innovation for the 590M series is the incorporation of stabilizing ribs directly on the magazines. These ribs engage precisely with the receiver when a magazine is inserted, ensuring an incredibly secure, positive lock-up. This robust connection prevents any wobble or play, contributing to consistent feeding and overall reliability.
• Dual Extractors: A hallmark of Mossberg pump-action shotguns, the dual extractors provide redundant reliability in extracting spent shells. Even if one extractor experiences an issue, the second one is there to ensure positive case extraction every time, minimizing the chance of malfunctions under stress.
• Twin Action Bars: The 590M utilizes twin action bars, which are crucial for smooth, non-binding pump operation. This design distributes the force of the pump evenly, preventing twisting or sticking, especially during rapid cycling. This contributes significantly to the shotgun's overall reliability and ease of use.
• Positive Steel-to-Steel Lockup: Mossberg's design ensures a strong, reliable steel-to-steel lockup between the bolt and the barrel extension. This provides exceptional strength and durability, safely containing the forces of firing, and contributing to the shotgun's long service life.
• Heavy-Walled Barrel: The 18.5-inch heavy-walled barrel on the 590M is built for sustained performance. A thicker barrel profile offers several advantages: enhanced durability, greater resistance to heat buildup during rapid firing, and improved inherent accuracy over lighter barrels. It’s also less prone to damage from impacts.
• Drilled and Tapped Receiver: The receiver of the 590M comes drilled and tapped from the factory. This pre-set feature makes it incredibly easy for users to mount optics, such as red dot sights or scope bases, directly to the shotgun, enhancing aiming capabilities and adaptability for various shooting disciplines.
• Ambidextrous Tang Safety: Located conveniently on top of the receiver, the ambidextrous tang safety is intuitive and easily accessible for both right-handed and left-handed shooters. This design promotes quick and safe operation under stress, a critical factor for any defensive firearm.
• Accessory Magazines for Versatile Capacity: The 590M's flexibility is further enhanced by the availability of accessory magazines. While the included magazine holds 11 rounds, shooters can also acquire additional magazines in 5, 10, 15, and an impressive 20-shot capacities. This allows users to tailor their shotgun's capacity precisely to their mission or preference, from compact home defense setups to high-capacity competition rigs. These magazines are readily available to ensure you always have enough firepower on hand.

Understanding the Specifications: What Do They Mean for You?

Knowing the specifications of a firearm helps users answer "Which shotgun specifications are most important for my use case?" The Mossberg 590M's details are tailored for optimal performance in tactical and defensive roles:

• Gauge: 12: The 12 gauge is the most popular and versatile shotgun gauge, offering a wide array of ammunition types from buckshot and slugs to birdshot and less-lethal options. This commonality ensures ammunition availability and compatibility.
• Capacity: 11 (Standard): With the included magazine, an 11-round capacity provides substantial firepower, significantly more than most standard tube-fed shotguns of similar barrel length.
• Chamber: 2.75": The 590M is chambered for 2.75-inch shells. This is the most common length for 12-gauge tactical and defensive ammunition, ensuring wide compatibility.
• Barrel Type: Heavy-Walled: As discussed, the heavy-walled barrel enhances durability, heat dissipation, and accuracy.

It also allows for the safe firing of all types of ammunition, including slugs and buckshot, without concern for damaging the barrel.
• LOP Type: Fixed: The length of pull (LOP) is fixed, providing a consistent shooting stance.
• LOP: 13.87": This length of pull is a common, comfortable size for many shooters, balancing control and reach.
• Barrel Finish: Matte Blue: The matte blue finish provides a durable, non-reflective surface that helps protect the barrel from corrosion and wear, while also minimizing glare.
• Stock Finish: Synthetic - Black: The synthetic stock is robust, weather-resistant, and low-maintenance. The classic black finish is practical and professional.
• Weight: 7.75 lbs: This weight strikes a balance between being substantial enough to absorb recoil and being light enough for effective handling and extended use.
• Length: 39.5": The overall length is compact, further emphasizing its maneuverability.
