I like Mossbergs and have a few. Recently when firing a new pistol grip version, I noticed that the shell follower began to stick in its most rear position after the last shot, and eventually great force was required to unstick it. The fix was simple. I replaced it with another from my parts bin, and if I think about it, I'll ask Mossberg to send a replacement. The post is not a bash Mossberg one. I have a question. Can extreme recoil after the last shot cause the follower to jump forward and then slam back and deform itself? I was shooting buckshot. this happened before the 25 round box was empty. My guess is that this follower was out of specs.
