The Mossberg 500 series has established itself as a benchmark in the world of shotguns, known for its reliability, versatility, and rugged design. The Mossberg 500 Pump 12 ga, 18.5″ Barrel Synthetic Pistol Grip, 6 rd variant is no exception. This article delves into the intricate details of this model, offering an in-depth review highlighting its features, performance, and suitability for various applications.

Design and Build Quality

The Mossberg 500 Pump 12 ga is crafted with a focus on durability and functionality. The 18.5″ Barrel perfectly balances manoeuvrability and accuracy, making it suitable for home defence and tactical applications. The synthetic pistol grip ensures a firm and comfortable hold, which is crucial during rapid-firing scenarios.

The synthetic stock is weather-resistant and lightweight, reducing the overall weight of the shotgun to about 6.75 lbs, making it easier to handle without compromising on performance. The dual extractors, anti-jam elevator, and twin action bars enhance reliability, ensuring smooth and consistent operation even under adverse conditions.

Performance and Versatility

Home Defense

One of the primary uses of the Mossberg 500 Pump 12 ga is for home defence. The 18.5″ barrel length is ideal for manoeuvring tight spaces like hallways and doorways. The pistol grip offers better control, especially in high-stress situations, allowing for quicker and more accurate aiming. The 6-round CapacityCapacity ensures you have enough firepower to handle multiple threats without immediate reloading.

Tactical Applications

The Mossberg 500 Pump 12 ga is robust and reliable for law enforcement and tactical applications. The synthetic stock and pistol grip provide a durable, easy-to-maintain solution, while the 6-round CapacityCapacity allows for sustained engagements. The shotgun’s ability to handle a variety of 12-gauge shells, from buckshot to slugs, makes it a versatile tool in the field.

Hunting and Recreational Shooting

While primarily designed for defence and tactical use, the Mossberg 500 Pump 12 ga can also be adapted for hunting and recreational shooting. The shorter Barrel and synthetic materials might not make it the first choice for all hunting scenarios, but it can be a reliable backup or secondary weapon. While beneficial for control, the pistol grip might not be as comfortable for prolonged hunting trips, but it excels in quick, reactive shooting situations.

Key Features

Adjustable Synthetic Pistol Grip

The synthetic pistol grip is a standout feature, offering superior control and comfort. This design is particularly beneficial in situations that require quick manoeuvrability and precision. The synthetic material is durable and easy to clean, ensuring long-lasting performance.

18.5″ Barrel

The 18.5″ barrel perfectly balances compact size and effective range. This length is ideal for close-quarters engagements, providing the shooter with a manageable firearm that does not sacrifice accuracy or stopping power.

6-Round CapacityCapacity

With a 6-round magazine capacity, the Mossberg 500 Pump 12 ga offers ample firepower for various scenarios. This Capacity is sufficient for home defence, tactical situations, and some hunting applications, reducing reload frequency and allowing the shooter to focus on the task.

Dual Extractors and Anti-Jam Elevator

Reliability is a hallmark of the Mossberg 500 series, and the inclusion of dual extractors and an anti-jam elevator ensures that the shotgun operates smoothly, reducing the chances of malfunctions. These features are critical in high-pressure situations where every shot counts.

Comparative Analysis

Mossberg 500 vs. Remington 870

When comparing the Mossberg 500 to the Remington 870, both are esteemed choices in the shotgun market. However, the Mossberg 500 stands out with its ambidextrous safety, located on the top of the receiver, making it accessible for both left and right-handed shooters. The Remington 870’s safety is positioned near the trigger guard, which can be less convenient in some situations.

Additionally, the Mossberg 500’s dual extractors provide an edge in reliability, ensuring spent shells are ejected more efficiently than the single extractor system found in the Remington 870. The Mossberg’s anti-jam elevator further enhances its operational smoothness, a crucial feature in high-stress environments.

Mossberg 500 vs. Mossberg 590

The Mossberg 500 and Mossberg 590 are often compared due to their similarities. The primary differences lie in the construction and intended use. The Mossberg 590 is designed for more rigorous military and law enforcement use, featuring a heavier barrel and higher capacity options. However, the Mossberg 500 offers more than enough reliability and performance for general home defence and civilian tactical use at a more accessible price point.

Customization and Accessories

One of the significant advantages of the Mossberg 500 series is the wide range of customization options and accessories available. Shooters can modify their shotgun to suit their needs better, whether adding a tactical light, an optic for improved aiming, or a more comfortable buttstock.

Tactical Lights and Optics

Adding a tactical light to the Mossberg 500 can significantly enhance its utility in low-light conditions, providing clear identification of targets. Optics like red dot sights can improve aiming speed and accuracy, especially in high-stress situations.

Extended Magazines and Stocks

Extended magazines are available for those requiring additional firepower, increasing the shotgun’s Capacity beyond the standard six rounds. Upgrading the stock to a more ergonomic or recoil-reducing model can improve comfort and shooting performance.

Slings and Carrying Options

A good sling can make carrying the Mossberg 500 more comfortable, especially during extended use. Slings that offer quick-adjust features or additional carry options can add to the versatility and ease of handling the shotgun.

Maintenance and Care

Regular cleaning and lubrication of the Barrel and action and trigger assembly will ensure smooth operation and longevity. The synthetic stock and pistol grip are easy to clean and resistant to environmental damage, requiring minimal maintenance compared to wood or other materials.
