Binds in magazine throat - GG&G Magazine Follower

I have a Mossberg JM Pro. I confirmed with the manufacturer that this item has a slighter tighter tolerance than the stock follower, meaning it fits a bit tighter in the tube. Sounds great, right? Well, I experienced some binding of the follower when loading the first shell. I could load the shell, but it took varying amounts of extra force to load it. The stock follower has a little more play, which allows the critical first shell to be inserted without resistance. The manufacturer suggests sanding the follower slightly and/or polishing the magazine throat with fine grit emory paper. I chose to go back to the stock follower and will not be looking for an aftermarket follower as sometimes stock is as good or better than an aftermarket part. YMMV.
