Frequently Asked Questions

How do you smooth a single-action trigger on a Smith & Wesson revolver?

To smooth a S&W single-action trigger, remove the trigger, secure it in a stoning fixture, apply Dykem to the sear, and carefully stone it with a medium grit India stone and honing oil. Monitor progress with Dykem, then reassemble and test.

What tools are essential for smoothing a revolver trigger?

Essential tools include a specialized stoning fixture for maintaining the correct sear angle, a medium grit India stone, honing oil for lubrication, and Dykem marking fluid to monitor the stoning process. A digital trigger pull gauge is also recommended for measuring results.

Can I stone my revolver's trigger without a fixture?

It is strongly advised against stoning the trigger without a proper fixture. A fixture ensures the correct sear angle is maintained, which is critical for safe and effective trigger function. Incorrect angles can lead to malfunctions.

How do I know when I've stoned the sear enough?

You monitor the stoning progress by applying Dykem to the sear. As you stone, the Dykem will be removed from the high spots. Continue stoning until the Dykem is evenly removed across the entire sear surface, indicating a smooth, consistent contact area.
