The trigger shoe on the Shilen feels much better because it's narrower with crisper edges. This makes the pull weight feel lighter than the Timney. I tried adjusting the pull weight on the Timney down light enough to feel similar to the Shilen, but the sear kept tripping when I'd close the bolt hard, so I had to add some more weight to it. Even though the true weight is probably around 1.5lbs, it feels like the Kimber or Shilen triggers when set to closer to 2-2.5lbs.
