WILSON COMBAT - Wilson Kit # 178

I’ve used this spring kit twice; on a model 29-3 and a model 329. Results are a much smoother and lighter trigger pull in both double and single action. In both cases an 8-lb double action pull weight is what I needed to adjust to in order to have consistent ignition of primers.

The main spring will not work on the S&W M1917 .45 DA revolver.

Excellent results

I over paid for a hard-to-find new 686+. So I was VERY disappointed when I discovered how lousy the trigger was. My son laughed out loud, "It's just so bad!" And my wife (accustomed to her superb K6S) said, "It won't go!" That stung. Local gunsmith said the action was smooth enough but the springs were unnecessarily heavy. Installing the Wilson Combat spring kit was a breeze, and now it feels like a revolver I am proud to own. 70+ rounds through it without a failure. I'll keep count until I am satisfied it is drop-dead reliable. I have a feeling it will be.

I've been using these for years, and keep a set in stock in my shop at all times. Most any S&W revolver I buy or trade into gets an initial internal cleaning, deburring and a set of these springs. They typically reduce the trigger weight on a K, L or N frame revolver by at least 20%. My most recently used set went into a S&W M-624 3". I highly recommend this part set.
