With the new Action Enhancement Trigger (part# 100-170), Duty/Carry Kit (part# 100-176) and combined Action Enhancement Trigger & Duty/Carry Kit (part# 100-171) for the Shield 2.0, you can dial in the trigger pull weight to the range you prefer. Using different combinations of the Apex and factory sear and trigger return springs you can set your trigger pull in the Shield 2.0 from approximately 5.8 lbs down to 4.1 lbs. This range is based on our test sample so your results may vary, especially taking into account differences in factory tolerances.
