Considerations & Trade-offs
- Designed specifically for S&W J Frame centerfire revolvers, so it is not a universal alignment tool.
- Intended for gunsmithing use; it helps with crane alignment but does not address other causes of lockup or action issues.
- The tool is precision-made to very tight tolerances, which supports accuracy but also means it is a specialized, single-purpose item rather than a general shop tool.
- Full instructions are included, but proper use still depends on careful setup and attention to the revolver’s condition.
