Anyone have troubleshooting experience with this pistol? My problem is twofold. First: Cock the action, place on safe, pull the trigger ( I can hear a slight audible click), disengage safety and the gun fires. Second: Occasionally the slide or bolt (whichever you want to call it) will after extraction/ejection - only go forward about 3/4" and there it freezes in place. I can pull it rearward and let loose but it still only goes that far forward again rather than all the way into battery.
