The History of Mossberg

In 1919, Swedish immigrant Oscar Frederick Mossberg, aged 53, launched a journey into firearms manufacture. Alongside his sons Harold and Iver, the trio established what was originally named Mossberg & Sons, Inc., operating out of a rented loft on State Street in New Haven, Connecticut.

The company’s vision was relatively simple: to manufacture durable and reliable firearms for the working class. Their first creation was a modest 4-shot Brownie pistol in .22 caliber, paving the way for a legacy of accessible, dependable firearms.

Just a few years later, in 1922, the Mossbergs produced their first rifle, the Model K. This .22 hammerless pump repeater rifle was in fact initially designed by the famous Arthur Savage but was finalized and improved by the Mossberg team.

As the world descended into war during the 1940s, Mossberg & Sons pivoted its focus to support the war effort. Securing a government license, they began producing tolerance tooling gauges, various machine gun parts, and components of the British Lee-Enfield rifle. During this era, Mossberg also introduced the Model 42MB, a .22 training rifle for British troops. An impressive amount of 45,000 units of Mossberg Model 42MB were produced. This period not only propelled Mossberg onto the global stage but also sparked a period of significant growth for the company.

The post-war years saw Mossberg contributing to the sporadic popularity of bolt-action shotguns, as they produced an array of these firearms. However, today, the company is most renowned for its exceptional pump-action shotguns. Particularly famous is the legendary Mossberg Model 500 pump-action shotgun introduced in 1962. In 1979, the US government awarded Mossberg a contract to produce the Model 500 as a combat-duty-rated pump shotgun. This led to the Model 500 being adopted by every branch of the US Military. By 2010, 41 different variations of the Model 500 were available on the market.

The company’s influence extends beyond firearm manufacturing. Mossberg has introduced several components now commonplace in the industry. For instance, Alan Mossberg developed a safety cable lock in 1989 that now comes as standard with almost every firearm sold today.

Mossberg celebrated 100 years in 2019, and even today continues to be a family-owned and operated business.

Mossberg 590 Shotgun Review

Introduced in 1987 as a part of the Mossberg 500 series, the Mossberg 590 is a pump-action shotgun available both as a full-size shoulder-mounted model and a smaller, 'stockless' Shockwave version. It is equipped with a 508 mm (20-inch) barrel and measures 1041 mm (41 inches) in overall length. In terms of ammunition storage, the 590 model has a full-length magazine parallel to the barrel. It is available either in 6-shot, 7-shot or 9-shot configuration.

The shotgun’s military-oriented design extends to its barrel and magazine, both of which have been adapted to meet military-grade specifications. The barrel is notably thickened, and the magazine is extended for greater ammunition capacity. Further military-focused additions include a barrel shroud for heat dissipation and a lug for attaching a bayonet. This modified design is known as the M590A1 and has been adopted as the standard shotgun in the United States military. The trigger mechanism of the 590 models operates at an approximate weight of 2268 g (5 lbs) and like on the 500 models, the receivers come drilled and tapped for optic mounting purposes. The safety is ambidextrous, placed on the action tang and is the same as on model 500.

The primary distinctions between the Mossberg 500 and 590 models lie in their magazine systems, materials used and overall types of use they are intended for. The Mossberg 500 is typically utilized for hunting and competition shooting and the 590 model, conversely, is designed primarily for law enforcement and military usage, with its open-ended muzzle and full-length magazine tube. Additionally, the 590 possesses a heavier barrel, dual lock-up on the magazine and includes polymer trigger guards. Some 590 models incorporate a ghost ring sight, which is not present in the 500 models.
