Sorry John and Chuck was typing while you guys answered.  I feel you are both correct in you assumptions.  I just didn’t  want to get into the balancing of springs.

I don't agree. 
I think for the most part people here on this forum are a sophisticated bunch that CAN have some fun with the PC auto correct while offering help and solving problems.

Thank goodness we can have some humor too!

JMHO, Unset rear trigger should almost but not quite touch the cocked sear.
Inertia of the set rear trigger will trip the sear.
Still have to do some spring balance, but not as bad.

John, did you miss the part about the ASSRA autocorrect here changing his correct post to "thingy"? I think the gentleman who started the this thread does know exactly what he means, and what it's called. But the forum's program changes C-OCK to "thingy" when he types the word without a hyphen in it as I just did.

  The BOD will cork their hammers and see if we can't get this crappity smacking cocking thingy corrected.

   PS: "crappity smacking" is a phrase I have never used or even heard. What I actually typed (just as an experiment) rhymes with mucking.

John, Yes I did get everything working.  In the original problem, the way I understood, was the gun worked as long as he set the rear  trigger.  In my experience that means the rear set trigger is contacting the sear when unset, which then will not allow the sear to engage the hammer notch. This is what Chuck was referring to when he said the unset rear trigger should not touch the sear.  The adjustment screw I believe you are referring to only comes into play with the trigger assembly set.  The only other mechanical issue, I could think of, was that front screw being tight,  binding the sear, as I think you brought up.  The reason I thought this is because when you set the rear trigger it moves the front trigger slightly and I thought possibly that movement freed the sear to move back into position.  The question, as he stated, with the issue is “it just started” so this is why I would question the spring balancing as the problem, why would it change.  That being said, he could check this in a couple different ways.  Simply loosening  the screw that retains the set trigger spring will take the pressure off and lower the front of the set trigger, this would only be to test the theory.  Or he could remove the spring and put shims under it which will accomplish the same thing more permanently.  Keeping in mind this is the balancing part of all this.  To tight, the sear will not catch the hammer notch or, to loose, and it won’t kick the sear hard enough to release the hammer.

I know, I got carried away but hope this helps someone.

I still am waiting to find out what a thingy is.
