I am holding a new Stan Shootoff release and a few ? come to mind. Why is the moving jaw flapping in the breeze when not cocked and locked down? Should there be a spring keeping the moving part open until it gets locked down? Design or malfunction on this one only. When cocked and locked, why can I still hear a rattle when moved side2side? Does the lack of a revolving head put too much torque on the D loop when shot with back of hand against face? BTW, the craftsmanship is superb.
