Abstract
A cartridge follower for pushing against cartridges in a tubular magazine of a shotgun. A front face of the follower has at least one forwardly protruding member offset from the center of the front face to be tactilely distinguished from a cartridge in the magazine, but which cannot contact a central primer of a backwards cartridge. A method for determining whether a shotgun is empty includes providing such a follower in the magazine, inserting a finger into the outfeed end of a magazine, and attempting to feel the protruding member.
