That I am surprised over! The Strain Screw is supposed to be tight to begin with - it is NOT an adjustment screw. If one wants to use it to slightly reduce tension on the Spring, the Strain Screw length should be adjusted - NOT the looseness/tightness of it - again, it SHOULD ALWAYS be fully tightened and the length adjusted. If in fact the Strain Screw is purposely backed out in your Revolver I would place a call to Gary and request a few new ones so that you can custom make the length you need to be 100% reliable. IMHO that was part of HIS job.I am unaware of any Professional GS's who leave Strain Screws purposely un-tightened.
