I did a similar mod with a different approach. I cut the stock transfer bar in half, clamped it to a piece of copper, spaced it so that the bar would actuate the sear much quicker. I then welded it back together and cleaned up the weld. Now the takeup is very little. Along with the comp trigger kit I now have a very light smooth 2.5-3# trigger with very little takeup and reset distance.
Why someone doesn't just make a longer transfer bar, I don't know.
