Smoothing the single action trigger pull on a S&W revolver can be a safe and easy job if you have the right tools. Larry Potterfield, CEO and Founder of MidwayUSA, explains the process for smoothing the single action trigger pull on a Smith and Wesson revolver using a Power Custom Sear Stoning Fixture. He begins by disassembling the revolver and removing the trigger. Once the trigger is clamped to the fixture and the unit is adjusted for the proper angle, a fine India stone is used to true of the sear surfaces. A bit of layout dye is applied to the sear during this process so that progress can be monitored. Once the surface has been polished, the trigger is lubricated and placed back into the revolver. The final step is to check the trigger pull with a pull gage.
