A fine revolver is a complicated device and should only be worked on by a competent gunsmith. Unlike automatics fine-tuning a revolver can be a time-consuming process. Essentially a revolver is like a simple clock and timing is everything. Generally speaking though high-quality revolvers don’t need much service unless they have been dropped on the butt or banged around in some other fashion.
The most common request I get for a revolver is to smooth out the action and lighten the trigger. About the lightest you can make the single-action trigger pull on any double-action revolver is around 4 pounds. Double-action pulls can be lowered to around 12 pounds while maintaining reliable ignition. A revolver carried for self-defense should not have its trigger pull lightened past installing manufacturer recommended springs. The double-action weight is determined by the heaviness of the spring and that spring weight also determines how hard the hammer hits a primer. If you make the trigger pull to light you can introduce reliability problems.

Action work also includes a trigger job. Most revolvers have case hardened parts and doing a trigger job usually requires the hammer sears to be re-case hardened. If you have someone yokel do your trigger work and he doesn’t re-case hardened the seer surfaces of the hammer they will wear out in short order and you’ll be looking to buy a new hammer. Color case hardened hammers occasionally lose their color when they get re-case hardened. There is not much that can be done about that, we try to guard against it but we do not color case harden.

The above prices are ballpark estimates only, but are pretty darn close. Because of the nature of revolver work is next to impossible to give a firm estimate without actually seeing it, but the above prices are usually pretty close. But they do not include return shipping or parts.
