Considerations & Trade-offs

  • Designed as a spring kit for New Model Ruger single-action revolvers, so it is not a universal option for other firearms.
  • The kit includes a 19 lb. hammer spring and a 35% reduced power trigger spring, which reflects a lighter setup than factory parts and may not suit every user preference.
  • An extra power base pin latch spring is included, so installation changes more than one component and may require careful fitting and function checking.
  • The product description frames it as a base for building a smooth, reliably functioning gun, but it does not provide performance specifics beyond the included spring changes.
