Compatibility
| Frame family | Fitment guidance |
|---|---|
| Smith & Wesson J Frame | Designed for compatible J-Frame revolver actions. Confirm the exact model, dash revision, action configuration, and existing spring geometry before ordering. |
Model-fitment note: The source listing identifies J-Frame compatibility but does not specify an exhaustive model-by-model or dash-by-dash list. Frame-family compatibility alone does not confirm fitment for every J-Frame generation.
Installation
Installation requires disassembly and reassembly of the revolver action. A qualified gunsmith should install and function-test the kit, especially when changing spring rates or trigger characteristics.
