The M14 was developed from the M1 Garand. Although the Garand was among the most advanced rifles of the 1930s/1940s, it was not a perfect weapon. At the dawn of World War II, progressive modifications led to the design of the M14. Changes included the addition of a fully automatic firing capability and the replacement of the eight-round "en bloc" loading with a detachable magazine containing twenty rounds. Due to the power of the 7.62 × 51 mm cartridge, the weapon was deemed virtually uncontrollable in automatic mode, so most M14s were locked in semi-automatic mode in the arsenal to avoid wasting ammunition in combat.
