The trigger is not designed by Mike Walker,rather by a fellow by the name of Sheeney(sp).DuPont bought the patient.And to extend the length of the patient,added the connector.That what I get for reading books,useless tidbits.
A Shilen trigger will go off,too, when the safety is released if the adjustments are too far out. I have seen this many times in jammed industrial equipment such as Radicon gear boxs.Damm near lost a finger to it.
