The Mossberg 590 has a metal trigger assembly
The Mossberg 590 is a series of pump-action shotguns manufactured by O.F. Mossberg & Sons. The 590 is an improvement over the 500, with a higher-capacity magazine and a metal trigger assembly. The 590A1 is the only model that features a metal trigger guard and a thicker-walled barrel. The 590 has the same barrel type as the 500, but with an improved magazine tube design, allowing for more ammunition capacity. The 590 is a popular choice for home defence and military use due to its reliability and durability.
The metal trigger assembly of the Mossberg 590 is often cited as a preference over the plastic trigger guard found in some other shotgun models. While some users may have concerns about the use of plastic in firearms, it is important to note that plastic materials can provide advantages in terms of manufacturing and cost-effectiveness. Additionally, advancements in polymer technology have resulted in durable and reliable plastic components used in firearms, including those designed for military and law enforcement use.
The Mossberg 590's metal trigger assembly contributes to its overall durability and reliability, which has made it a trusted choice for both civilian and military users. The 590's design offers a balance of performance and functionality, with features such as dual extractors, steel-to-steel lockup, ambidextrous safety, and twin action bars. The metal trigger assembly ensures a smooth and consistent trigger pull, enhancing the shooting experience and accuracy.
While the Mossberg 590 is known for its metal trigger assembly, it is worth noting that some variations of the 590 may have plastic components in other areas of the firearm. For example, the 590 Shockwave, a variant of the 590, features a unique bird's-head grip designed to minimise felt recoil. This grip, while not part of the trigger assembly, showcases how Mossberg incorporates innovative designs and materials to enhance the performance and usability of their firearms.GlockTalk users have also noted that the 590's plastic trigger guard has never caused them any problems.

The Mossberg 500 has a plastic trigger guard
The Mossberg 500 is a series of pump-action shotguns. It was designed in 1961 by Carl Benson and was originally intended for use by hunters. However, due to its reliability and low cost, it quickly became popular with law enforcement. The Mossberg 500 has seen many variations over the years, including the Mossberg 590, which is an improvement on the 500 in many ways. One of the most notable differences between the two models is the trigger guard.
The trigger assembly on the Mossberg 500 has been known to break. In one instance, a user reported that the plastic trigger assembly on their Mossberg 500 snapped off from the receiver. Mossberg replaced the trigger assembly with another plastic one, and the gun worked fine after that. This suggests that while the plastic trigger guard on the Mossberg 500 may not be as robust as the metal one on the 590, it is still functional and can be replaced if necessary.
It is worth noting that the Mossberg 590A1, a military-grade variant of the 590, is the only model in the 590 series that features a metal trigger guard and a thicker-walled barrel. The standard Mossberg 590 has the same barrel type as the 500, which is the standard thickness. This may be a factor in why some 590 models have plastic trigger guards, as the thicker barrel on the 590A1 likely requires a more durable trigger guard.
While some gun enthusiasts prefer metal components, plastic has its advantages. Plastic is a lightweight material, making the gun easier to carry. Additionally, plastic can make the manufacturing process cheaper, which can result in a more affordable product for consumers. Ultimately, the choice between a metal or plastic trigger guard comes down to personal preference, as both options have their pros and cons.

The Mossberg 590 is heavier than the 500
The Mossberg 590 is a shotgun designed for military and law enforcement use. It is heavier than the Mossberg 500 due to several factors, including its magazine design, barrel thickness, and additional features.
The Mossberg 500 and 590 are two popular models of shotguns produced by O.F. Mossberg & Sons. The Model 500, designed in 1961, was originally created for hunting but quickly gained popularity with law enforcement due to its reliability and affordability. The Model 590, on the other hand, was designed for military and law enforcement use and offers a range of customized stock and sight features.
One of the main differences between the Mossberg 500 and 590 is their size and weight. The 500 is shorter and lighter, making it more manoeuvrable and easier to handle. In contrast, the 590 is longer and heavier, providing a more stable platform for shooting. The increased weight of the 590 is partly due to its thicker barrel and heavier receiver, which enhances its durability and ruggedness.
Another factor contributing to the weight difference is the magazine design. The Model 500 has a closed magazine tube, while the 590 has an open-ended magazine tube. The 500's magazine is designed for easy barrel changes, while the 590's magazine provides a more traditional cap, offering maintenance advantages. Additionally, the 590's magazine has a higher capacity, holding up to nine rounds compared to the 500's six rounds.
The Mossberg 590 also includes several additional features not found on the 500. It has a metal trigger guard and safety, while the 500 uses plastic parts for these components. The 590's metal construction contributes to its increased weight. Additionally, the 590 features a bayonet lug for attaching a bayonet, which is useful for close-quarters combat.
The weight difference between the Mossberg 590 and 500 shotguns is influenced by a combination of factors, including their magazine design, barrel thickness, and the inclusion of additional features. These factors contribute to the 590's heavier and more durable construction, making it well-suited for military and law enforcement applications.

The Mossberg 590A1 is the only model with a metal trigger guard
The Mossberg 500 series is a family of pump-action shotguns with a range of models, including the 500, 505, 510, 535, and 590. The 590 is an improvement over the 500, with a higher-capacity magazine and a metal trigger guard, as opposed to the plastic one found on the 500. However, some sources indicate that certain 590 models also feature plastic trigger guards.
The Mossberg 590A1 is a variant of the 590 model and is considered the military-grade heavy barrel version. It is the only model within the 590 series that features a metal trigger guard and a thicker-walled barrel. The 590A1 is available with five- and eight-shot magazines, and it also allows the use of magazine extensions to further increase ammunition capacity. Its heavier barrel has been noted to affect the balance of the shotgun.
The 590 and 590A1 models differ from the 500 series in their magazine tube design. The 500 magazines are closed at the muzzle end, while the 590 magazines are open at the muzzle end, allowing the barrels to fit around the magazine tube. This design variation facilitates easier barrel changes in the 500 model.
The Mossberg 590 series has been popular for its ruggedness and reliability, finding use in military, law enforcement, and home defence contexts. The 590A1, with its metal trigger guard and heavy barrel, is particularly sought after for its durability. However, some users have expressed a preference for plastic trigger guards, citing their durability and the fact that modern firearms like Glocks and H&Ks extensively use plastic in their construction.
In summary, the Mossberg 590A1 stands out within the 590 series by offering a metal trigger guard and a heavier barrel. While this differentiates it from other models with plastic trigger guards, the preference between metal and plastic components ultimately comes down to personal preference and intended use.
