Magnum MC

The Magnum MC is a heavy semiautomatic pistol in Marathon that fires Heavy Rounds from a modular frame equipped with muzzle and optics rails, offering the highest precision multiplier of any pistol in the game at 2.1x. With 33 damage per shot, a 12-round magazine, and 21 meters of effective range, the Magnum MC prioritizes stopping power and shot quality over fire speed: at 138 RPM it is the slowest-firing pistol in Marathon, but each round carries the weight to challenge even shielded opponents when shots land on target. Its 1.4x zoom and 58.3% accuracy score position it as a deliberate marksmanship sidearm rather than a panic-fire backup.

The Magnum MC's 2.1x headshot multiplier is its defining trait: a well-placed precision shot from this pistol deals significantly more damage than its base 33 per round suggests, making it a strong finisher for runners who can maintain calm aim under pressure. Its 81.5% recoil and 1.28 aim assist are manageable for a heavy pistol, though the 1.9-second reload rewards intentional shot selection over trigger mashing. Using Heavy Rounds means it competes for the same ammo pool as weapons like the Repeater HPR and Twin Tap HBR; pairing it with those weapons creates a fully self-sufficient Heavy Rounds loadout. Compatible mods including the Oracle Lens and Rangefinder Lens give veterans meaningful customization options. The Magnum MC suits precision-minded runners who want a punishing sidearm that rewards accuracy over volume.
