Ellifritz is not one to just pass along poorly sourced rumor. It looks as if the 8 pellet loading of FFC might be discontinued.
One of the biggest problems shotguns have in the defensive role is the plug-fucking stupidity of the market surrounding shotguns. A lot of agencies buy the 9 pellet load because 9 pellets is the tradition, regardless of whether the 8 pellet load performs better. With more and more agencies ditching shotguns altogether because they don't know how to train people on them, I can imagine that the LE demand for the 8 pellet load is continually shrinking.
The civilian market for defensive shotguns is hardly any smarter when it comes to ammunition selection.
I'd say stock up, but 8 pellet has basically been unobtanium since the COVID panic started.
