Well guys, this is much, much harder than it looks in the Mcorbo video. In fact, I couldn't do it. The spring is barely visible from above (the bottom) and not visible at all from the front. I gave up.

But then I thought, since that spring isn't going anywhere, why don't I just leave the adjustment screw out entirely? So I did and the trigger pull dropped from 3 3/4 pounds to 2 1/4 pounds.
