I don’t recommend the Type-2 Reduce Power Mainspring on a Square Butt N Frame Pistol. This actually significantly increased the double action pull weight of the trigger. It may work on a Round Butt Pistol but the product description was for any S&W K,L,N Frame Pistols.

Lowers pull, predictable outcome and still pops off primers. What's not to like?

Installed 12lb spring. 2 1/2 trigger now. I left the original main spring because I mostly shoot single action.
