Main spring and trigger adjustments

First topic message reminder :

I recently built a 45cal 1911. Used EGW kit for hammer/sear/disconnect or. Initially I experienced some light strikes (~30% failure rate) increased the main spring incrementally to 19, 20, & 21 lbs springs. Trigger felt great with a 19# spring but had to increase spring weight up to 21# before light strikes have been eliminated. Now the trigger does not feel great anymore: feels much heavier and somewhat clunky compared to the lighter springs. Is there something I can do to offset this increase in trigger weight/sear engagement weight? 

Maybe adjust one of the fingers on the flat spring behind the grip safety to adjust sear & hammer engagement?

I put a piece of paper between the back of the barrel hood and the slide to see how many pieces of paper will fit as you suggested. The gun with the light strikes will not go into battery with one sheet of paper inserted without me shoving hard on the back of the slide to get it into battery the last 1/10” or so. Once I got the slide closed completely and barrel into battery with paper between back edge of barrel hood and slide face it was kind of locked shut and took some significant extra effort to open it back up. 

I also compared this to the two AccuracyX 1911 BE guns that I have and they behaved in a similar way. I do not have any issues with the AXI pistols so I am using them as a baseline to compare against/ control group.
