Adjusting Trigger Pull on EMP4 LW Champion

Does the left branch of the sear spring adjust the trigger pull force on the EMP4. I received the gun from the factory with average force of 2.5-3.0 lbs and SA adjusted it on warranty to 5.0 lbs. I actually prefer the lower force for accuracy with my small hands. So, if I disassemble the lower receiver to the sear spring and bend back the left branch (as on a regular 1911), does that lower the trigger pull force?
If you've actually done this and know that it does/does not work. then I'd appreciate your answer. Thanks for your time.
