I initially installed the Competition Reduced Spring Kit in an S&W 327. The results were very impressive; much lighter and smoother trigger pull (I use Federal ammo). I subsequently installed the Competition Reduced Spring Kit on an S&W 325, 625, and 627 with equally impressive results. I couldn't be happier. And it's worth noting that there is a short instructional video on the internet wherein Eli demonstrates the process. Bravo TKC.
