1911 plunger tubes come loose every now and then. Most stocks are cut to support and help hold the plunger tube in place. The AFS stocks are too thin to do this. It's really no problem. One ought to keep an eye on their plunger tube's tightness anyway and have it replaced or restaked if it loosens.
The lack of plunger tube support is certainly much more excusable on the AFS stocks than it is on certain full-thickness stocks which do not support the plunger tube.
