Pumps have several advantages as waterfowl guns. First and foremost, they are reliable. Where grit, mud, ice, and moisture can cause a semiauto to fail, pump guns will keep on working in miserable conditions. Second, they aren’t finicky about ammunition. Because the action is powered by the shooter—not expanding gases or recoil—a pump will cycle any load no matter how light. Third, pumps are tough and inexpensive, and if you want a gun that you don’t have to baby or worry about, a pump might be the best duck hunting shotgun for you.
