Seems to me that the problem with the light trigger settings with this CDG action is that with the fixed bolt handle
the cocking piece does not strike the trigger sear. The bolts forward movement is stopped when the handle hits
the primary extraction cam, then when the bolt is rotated the cocking piece engages the trigger sear.
With the pivoting handle the cocking piece strikes the trigger sear with the full force you apply manipulating
the bolt and at the lighter weight settings the trigger will not hold.
That is exactly why the pivoting bolt handle is a bit more picky about triggers, if you have the trigger timed to zero cocking/decocking on close or slight overcocking on close the cocking piece hits the trigger sear pretty good when running the bolt quickly as the sear and the chambering cartridge are the only things slowing the bolt down. If your trigger is very light with minimal sear engagement, it can lead to the sear not catching the cocking piece so the firing pin will fall as you rotate the bolt handle closed.
With the fixed lever the extraction cam takes the initial hit and slows the bolt down so the sear doesn't get shocked as much, so it's more tolerant of very light triggers.
(Technically, the first thing to contact the action on the CDG (and Archimedes) when closing the bolt is the bolt shroud locking pin making contact with the rear face of the action body-- but the bolt shroud locking pin doesn't have enough spring rate to be meaningful in terms of slowing the bolt down when you're running the bolt quickly.)
Going from my experience with a couple of Archimedes, if you time the trigger for about 0.010" of decocking on close and provided your ammo isn't headspaced 0.010"+ short, that means the chambering cartridge will do the majority of slowing the bolt down while the cocking ramp on the bolt will hold the cocking piece off the trigger sear. The cocking piece will only contact the sear while you're rotating the bolt handle closed and the cocking piece comes off the cocking ramps at the back of the bolt body during the slight decocking on close, which is a much gentler way of passing off the cocking piece to the trigger sear and less likely to have it "skip" off the sear. You don't want to time it for too much decocking as that will reduce firing pin travel and overall energy imparted to the primer which might invite increased SDs or light strike misfires.
In my Archimedes I run BnA 2 stage tacsports set to 2# total (1# 1st stage which is simply a spring controlling trigger shoe rotation before it contacts the sear lever, while the 2nd stage which is the actual sear lever movement and release is 1#; so it's the equivalent to a single stage BnA set to 1#)-- I have them timed to about 0.008" decock on close and I've never, ever had the firing pin follow the bolt closed even running it as fast as I can on the bench with no mag or ammo in the action to help slow the bolt down. I expect the CDG will behave very similarly, only it will be even easier to adjust the trigger timing with the trigger hangars (unlike the Archimedes that requires swapping or grinding the cocking piece to time the trigger.)
