Hi Bill, thanks for that... the lighter pull really helps.
To answer the question requires a little background info... hope you can bear thru this:
Look at the three circles in the above picture. They show the key parts of the lock for semi-auto action.
In the white circle, the pawl has been rotated forward by the hammer travel. This, in turn, pulls the trigger link off of the trigger sear (pink circle).
With the link and the trigger sear uncoupled, the hammer sear and trigger sear are free to latch (aqua circle) when the blowback occurs... otherwise, you'd have full-auto. The 600 can be made full-auto by removing the 'dog' on the pawl that pulls up on the trigger link (white circle again)... I've never tried it (too chicken
). It can also go full-auto due to a malfunctioning mechanism...If the pawls gets broken, or if there's excessive wear to prevent the sear latch (aqua circle)
So getting back to the question, the trigger spring operates independently from the semi-auto components so there's no effect -
