Are Wilson Combat trigger spring kits for K frames worth the money and effort ? I have a new model 66 and would like to improve trigger , lighter and smoother, I don't want to spend a lot for a gunsmith trigger job . I'm capable of changing springs and I don't want to get into honing parts .

Yes or a Wolff

The cheapest way to get it smoother is just to use it. The old revolvers that are so slick didn't come that way new, either.

As to lighter, it depends on what you use it for. I use lighter springs in my IDPA revolver, but not in my carry one.

I just found this thread after doing a search for the topic.

I bought a Wilson Combat spring kit for one of my 686s. It came with a hammer spring and three different trigger return springs.

Here's what I don't understand: The Wilson hammer spring made no noticeable difference at all with regard to the double action trigger pull over the stock spring. This is going by feel, I admittedly did not use a scale. If anything, I thought the Wilson spring actually felt a tiny bit stiffer than stock.

What is supposed to be the advantage of the Wilson spring?

Now, the trigger return springs did have a noticeable effect. I went with the 13lb one.

I use Wilson springs in all my revolvers. The big advantage I find is that because of the kink in the upper end of the hammer spring you can back off the strain screw without causing spring bind. In a straight spring without the strain screw to start th flex you will get a definite bind at the start of the stroke.
With the Wilson you can lighten the trigger pull to the point of inconsistent detonation. Be sure to test to get what works best for you and then lock-tite the screw.
