About the Marlin

The story of the Marlin company started in 1836 in Connecticut, the birthplace of John Mahlon Marlin. As the civil war commenced, he began his working carrier at the Colt plant in Hartford. Five years after the war, he started his own company in New Haven, Connecticut, and named it Marlin Firearms. Between 1870 and 1899 the company produced a manifold of pistols, revolvers, and derringers with one of the biggest strategic moves being made in 1881 when it introduced its first lever-action repeating rifle – Model 1881. Another breakthrough was made by the company with the introduction of the 1889 Model - a lever rifle with a solid top that ejected the empty cartridges out of the side of the receiver. This was the feature that in later years became equated with the term "Marlin Safety". The concept was further utilised in the following years on a .22 rimfire lever-action - Model 1891. That led to the development of Model 39, introduced in 1922, with almost 3 million rifles produced to date. Two years later, a new model was released under the name Model 1893 which was later renamed the Model 1936/Model 36, manufactured up until 1948. It was improved and renamed Model 336 in the same year. For some time, Marlin also produced rifles for Savage as they lacked manufacturing capabilities.

After the death of John Marlin, his two sons inherited the business, and the company went through several ownership changes. It was sold around 1915 to William Bonbright & Co. and Kissell-Kinnicut & Co. - a group of investors associated with J.P. Morgan. Shortly after, A.F. Rockwell became the president of the company and renamed it Marlin Rockwell Corporation in 1916; however, in 1919, John. F. Moran took over. After World War I, the economic decline became apparent, and the company shifted its focus to various other businesses. They manufactured ball bearings, roller bearings, radiators, wires, bombs, and even automobiles. In 1921, a simplified manufacturing line was formed that specialized in the production of sporting firearms and was named Marlin Firearms Corporation. Due to a decrease in sales, the company was put on the auction block in 1924 when it was bought for a small price of $100 by lawyer Frank Kenna.

The after-war years offered new opportunities and the sales gradually improved. In 1949, Model 36 was redesigned and renamed Model 336. It is still manufactured today as one of the most popular lever-action rifles in the world. Additionally, the company pioneered the Micro-Groove rifling which was supposed to allow for better shooting accuracy and was the standard on Marlin rifles up until the 1990s.

In 1956, the company introduced Model 56 which featured a modernised lever design with a short lever throw allowing for fast reloading. The series was later named Marlin 'Levermatic'. Shortly after, Model 57 and a centrefire Model 62 were presented. However, the Levermatic series did not sell too well and was discontinued in 1973. Some of the most recognizable models from that time were Glenfield Model 30, Model 444, and reintroduced Models 1894 and 1895 which are still manufactured today. With new regulations taking place, Marlin added a cross-bolt safety to their rifles around 1983. Numerous models were presented in later years such as Model 700, Model 780, Model 80, Model 7000, Model 2000, Model XL7, and XS7 along with some pump-action shotguns like Models 16, 17, 19 etc.

In 2007 Marlin was bought by Remington Arms, however, the ownership changed again in the following decade. Since 2020, the Marlin is owned by Sturm, Ruger & Co. Over 6 million guns and 150 years later, they carry on Marlin’s legacy of innovativeness and quality.

Marlin Model 45 Carbine Rifle Review

Marlin Model 45 is a semiautomatic carbine rifle introduced in 1986 and manufactured up until 1999. Structurally, the rifle is comparable with Model 9 with the major differences being the magazine and the cartridge. It is chambered for a .45 ACP handgun calibre which allows for the usage of the same calibre in multiple weapons. The magazine is a copy of the one featured on the Colt Model 1911 pistol, making it interchangeable between the two. Model 45 has a 7-shot magazine whereas the Model 9 is available in both – 12 and even 20-shot versions.

The safety mechanism is carried out similarly – both rifles use the Garand-type steel lever which is positioned in the forward section of the trigger guard. It is marked with S and F initials and activated by pushing the lever rearward as far as possible, moving it into the inner side of the trigger guard. Additionally, the rifle comes with a ‘last shot’ feature which is automatically activated when the magazine is empty. It allows for the bolt feeding gate to stay open and lets the user know that the last shot has been fired. To switch to the manual bolt hold-open position, the latch on the left side of the receiver must be pulled and the charging handle released. The trigger is factory pre-set for a crisp and controllable pull.

There is a red indicator that protrudes from the rear end of the bolt when a cartridge is in the chamber. The steel receiver is drilled and tapped for scope mounts and comes with a flat surface. Model 45 comes with the adjustable folding rear sight and a ramp front sight with bead front sight post with open or closed sight hood. Quick-detachable swivels are available as an accessory.

The possible barrel length for Marlin 45 is 419 mm (16 ½-inch).
