The JP spring kits do quickly reduce the pull weight, but not creep/smoothness. And you need to be aware that your lower may not reliably fire mil spec primers anymore due to reduced hammer spring pressure. It was OK for my Grendel since I reload, but I would not use them on any serious usage lower that may see 5.56 milspec ammo if it has to work everytime.
You can see some benefit of the JP kit just by putting one leg of the hammer spring under the (trigger?) pin rather than over. It has to be the leg not riding in the pin notch!
It does not reduce the other spring pressure, but some folks clip those springs. For me, it was just easier to get the JP spring kit rather than clip.
