Magazines with tilt-resistant followers have a tubular body defining a passage, a follower movable within the passage, and the follower including a roller. The follower may have rollers on the front and the rear. The follower may have two rollers on at least one of the front and the rear. The follower may have a platform portion, a tine extending perpendicular to platform portion, a roller connected proximate to the platform, and a second roller connected proximate to a free end of the tine. The follower may have front and rear tines, each tine having a pair of rollers. The tubular body may define a major plane, and the roller may define a roller axis perpendicular to the major plane. The follower may define a transverse aperture receiving a pin, and the roller may be supported on the pin. The roller may include a set of ball bearings.
