Just a heads up. Fairly new Mark IV, couple thousand rounds through it.
The receiver frame screw (#3 in their exploded diagram) worked itself out and disappeared. Part of the hinge mechanism that anchors the barrel to the front of the lower.
Discovered it while cleaning. Apparently it’s a fairly common issue and could have been fixed with a bit of loctite, if I’d caught it in time.
I’m lining up a replacement part. But if you shoot one of these you may want to check yours out.
