The M3 Grease Gun: A Reliable and Deadly Submachine Gun of World War II
The M3 Grease Gun, also known as the M3 Submachine Gun, was a lightweight, reliable, and deadly submachine gun used by the United States military during World War II. Designed to replace the Thompson submachine gun, the M3 was used by the US Army, Navy, and Marine Corps from 1942 to 1950. In this article, we will explore the history, design, and features of the M3 Grease Gun, as well as its impact on the battlefield.
History of the M3 Grease Gun
In the early 1940s, the US military was in need of a new submachine gun that was lighter, cheaper, and more reliable than the Thompson submachine gun. The Thompson, while effective, was heavy, expensive, and prone to jamming. In response, the US Army Ordnance Department issued a request for a new submachine gun that could be produced quickly and at a lower cost.
The M3 Grease Gun was designed by George Hyde, an engineer at the Inland Manufacturing Division of General Motors. Hyde’s design was simple, yet effective. The M3 used a blowback operating system, which eliminated the need for a gas piston and cylinder. This design made the gun lighter, cheaper, and more reliable.
The M3 Grease Gun was produced by General Motors and the Guide Lamp Corporation from 1942 to 1945. Over 600,000 M3s were produced during World War II, making it one of the most widely used submachine guns of the war.
Design and Features
The M3 Grease Gun was designed to be a simple, reliable, and easy-to-use submachine gun. It weighed just 8.5 pounds, making it one of the lightest submachine guns of its time. The M3 was also relatively short, measuring just 29.7 inches in length.
The M3 used a blowback operating system, which eliminated the need for a gas piston and cylinder. This design made the gun lighter, cheaper, and more reliable. The M3 fired the.45 ACP cartridge, which was widely used by the US military during World War II.
The M3 Grease Gun had a number of features that made it well-suited for combat. It had a selective fire switch, which allowed the user to choose between semi-automatic and fully automatic fire. The M3 also had a folding stock, which made it easier to carry and store.
