The M1941 Johnson rifle is a semi-automatic firearm designed by Melvin Johnson in the early 1940s. It was chambered for the .30-06 Springfield cartridge and featured a unique short-stroke gas piston system, which allowed for reliable cycling and reduced recoil. The rifle had a distinctive appearance, with a wooden stock and a detachable magazine that held ten rounds. Although the M1941 Johnson rifle was innovative, it saw limited use during World War II, primarily due to the U.S. military's preference for the M1 Garand. Only about 20,000 units were produced, making it a rare collector's item today. Its design influenced later firearms, showcasing advancements in semi-automatic technology.
