Coil Submachine Gun

The Coil Submachine Gun first appears in Grimm's Legacy as a compact electromagnetic weapon capable of delivering sustained fire from a hundred-round magazine. Its coil-based propulsion system marks a significant departure from traditional chemical firearms, offering greater reliability and reduced recoil in close-quarters combat. Throughout the series, the weapon evolves from a specialized prototype into a standard-issue sidearm for elite units, reflecting broader technological shifts in personal armament.
