The semi-automatic, gas-operated, eight-shot M1 rifle, popularly known as the “Garand” after its inventor, John C. Garand, was the primary American service rifle of World War II. Developed at the venerable government-owned Springfield Armory and adopted in 1936, the M1 rifle was chambered for the standard .30 caliber cartridge (.30-'06 Sprg.). It had a 24" barrel and weighed 9.5 lbs. When the war ended in August 1945, more than 4 million M1 rifles had been produced. (Photo courtesy of the Bruce N. Canfield collection)
