My Mink built "Jackson Package" has a much lighter trigger pull than my CZ Custom Shadow Target, 6lbs da vs 8lbs da, and probably a lb lighter on the SA side of the house. I have not changed springs on either of them, and it could be solely because my Mink build has a lot more rounds and dry fire on it. Both are butter smooth, but i'd have to drop a pre-b disconnector and a CGW 11.5 mainspring in the Shadow Target to elevate it from backup gun duty. I guess it depends on what you are looking for and what your expectations are, both are great, I just prefer my AA build to the CZC build. YMMV
