Overview
Designed for 1911 trigger work, this tool gives gunsmiths a controlled way to study and adjust hammer and sear engagement during stoning and fitting. Its adjustable setup supports incremental changes to primary and secondary sear angles, while the built-in 20X magnifier helps with close inspection of the contact surfaces. The included pins, roller, and instructions make it a focused bench tool for careful work on a light, clean-breaking trigger. It is a specialized piece of equipment, so it makes the most sense for users who are already working on 1911 action tuning and want a more precise setup.

Considerations & Trade-offs
- Designed for 1911 hammer and sear work, so it is specialized rather than a general-purpose trigger tool.
- The 20X magnifier supports close inspection, but the tool still depends on careful setup and user skill to interpret and apply what it shows.
- It is built around incremental cutting of primary and secondary sear angles, which means it is intended for controlled fitting work rather than quick adjustment.
- The included instructions help with setup, but this is still a precision gunsmithing tool that may be more involved than casual users need.
