Overview

This hand-held fixture is designed to hold a 1911 sear in position while you stone the contact surfaces at the correct angles. It is intended for careful trigger work, helping you refine the primary sear angle and maintain proper thumb safety operation during the process. The included .020" stainless steel shim adds a measure of control by helping limit material removal and protecting the fixture body from wear. Built from steel with a black oxide finish, it is a straightforward bench tool for shooters and gunsmiths focused on precise 1911 trigger adjustment.

Considerations & Trade-offs

  • This fixture is intended for sear stoning work, so it’s a specialized tool rather than a general-purpose 1911 maintenance item.
  • The .020" shim helps limit material removal, but it also means the process is deliberately conservative and may require patience to reach the desired result.
  • Setup depends on correctly adjusting the setscrew and following the included instructions, so it is best suited to users comfortable with careful trigger work.
  • Its compact hand-held size is practical at the bench, but it does not replace the need for proper stoning technique and attention to sear geometry.
