The Mossberg 500 and 590 pump action shotguns will always work better with a high-quality follower. As you may know, the follower is the part of the shotgun which pushes the ammunition shells along as they’re being used up. The spring tension behind the follower is what keeps it moving along with the shells that remain in the magazine. The more durable and tough the follower is, the better it will function in performing this task. You won’t get this kind of strength with the factory-made follower that comes with your Mossberg shotgun. That is why you need an enhanced follower for the Mossberg that can go beyond the limitations of the factory follower and give you a better shooting experience in general.
