I watched a video on youtube about the Shield and found that I was measuring the trigger pull incorrectly. It turns out that after the trigger broke, my Lyman trigger pull gauge was getting a reading when the trigger stopped at its most rearward point. If I watch the readout on the scale as I pull the trigger, I can see the reading just as the trigger breaks. The trigger pull is actually averaging about 7 3/4 +- 1/2 Lbs. So that makes it 1 1/4 Lb heavier than the specifications call for.
