When I load a full 7 rounds in the tube the selector switch will not move. If I only load 6 it works fine but with 7 it can’t clear the lip of the cap. The KSG is supposed to hold 7 @ 2 3/4” but If I load 7 I’m unable to move the switch to load the other tube. It’s as though the spring is over-compressed. Has anybody else experienced this and or found a remedy?
