Considerations & Trade-offs
- Designed for Old Model and Old Army revolvers only, so it is not a universal spring kit.
- The kit includes reduced-power hammer springs, which can change the feel of the action compared with the factory 23 lb. spring.
- An extra-power base pin latch spring is included, but the kit does not address other parts of the revolver's function or setup.
- Spring changes can affect trigger pull and operation, so installation and tuning may be needed for the desired result.
