Delving into the intricate realm of firearms, we embark on an exploration of the transformation process that empowers a single-action revolver to embrace the fervor of a race-ready performance. Converting a single-action revolver to flaunt the characteristics of a race gun not only unleashes its true potential but also bestows the shooter with an ergonomic advantage, enabling them to unleash lead downrange with unparalleled speed and accuracy. However, embarking on this journey requires a thorough understanding of firearm mechanics, meticulous attention to detail, and unwavering commitment to safety.
To initiate this metamorphosis, the single-action revolver must shed its traditional hammer and sear configuration in favor of a race-optimized setup. This entails replacing the factory-installed hammer with a competition-inspired “race” hammer, meticulously designed to minimize lock time—the critical interval between trigger pull and bullet departure. Concurrently, the sear undergoes a transformation, adopting a “speed sear” profile that provides a crisp, short reset, ensuring lightning-fast follow-up shots. These modifications forge a foundation that supports the revolver’s newfound ability to unleash a torrential downpour of rounds with surgical precision.
In addition to internal alterations, the exterior of the revolver undergoes a series of enhancements that elevate its ergonomic profile. Extended grips, meticulously crafted from exotic materials, offer an unwavering connection between shooter and firearm, promoting effortless recoil management and intuitive target acquisition. The integration of an under-barrel accessory rail unlocks a realm of customization possibilities, accommodating lasers, lights, and other tools that enhance target illumination and overall weapon handling. The transformation culminates in a firearm that seamlessly harmonizes with the shooter’s physiology, enabling them to harness the full potential of their marksmanship.
Preparing the Frame for the Conversion
The frame is the foundation of the revolver and must be able to withstand the increased pressure and recoil forces generated by the conversion to a race revolver. This requires several modifications to the frame:
- Modifying the Cylinder Stop and Cylinder Length
- Installing a Cylinder Release
- Installing a Hammer Stop
- Strengthening the Frame Rails
The cylinder stop must be modified to accommodate the shorter cylinder length. A shorter stop will prevent the cylinder from turning prematurely when the trigger is released. The cylinder length must also be shortened to match the new stop position.
A cylinder release is a lever or button that allows the cylinder to be opened and closed quickly. This is necessary for rapid reloading during a race.
A hammer stop prevents the hammer from over-traveling when the trigger is released. This is important for preventing damage to the revolver and maintaining consistent trigger pull.
The frame rails, which support the cylinder and barrel, must be strengthened to handle the increased recoil forces. This can be done by adding additional material, such as welding on reinforcement ribs.
Frame Modifications Table
| Modification | Purpose |
|---|---|
| Cylinder Stop Modification | Prevents premature cylinder rotation |
| Cylinder Length Shortening | Matches the new stop position |
| Cylinder Release Installation | Enables quick cylinder opening and closing |
| Hammer Stop Installation | Prevents hammer over-travel |
| Frame Rail Strengthening | Handles increased recoil forces |
Installing the Cylinder Release System
The cylinder release system is a crucial component of a race revolver, allowing for quick and efficient cylinder rotation. Here’s a detailed guide to installing this system:
1. Disassemble the Revolver
Before starting, ensure that the revolver is unloaded and the action is open. Use a screwdriver or punch to remove the cylinder release screw and detach the old cylinder release system.
2. Install the New System
Align the new cylinder release system with the frame and insert the retaining screw. Tighten the screw firmly, but avoid overtightening.
3. Adjust the Cylinder Release
This process involves ensuring that the cylinder release lever operates smoothly and releases the cylinder when desired. Here’s a step-by-step explanation:
- Fit the Cylinder: Place the cylinder into the frame and rotate it manually to check if it fits properly. If it binds or does not rotate freely, the cylinder release adjustment is likely too tight.
- Adjust the Screw: Use a screwdriver to loosen or tighten the cylinder release screw as needed. Turn the screw clockwise to tighten and counterclockwise to loosen.
- Test the Release: Rotate the cylinder manually again to ensure that it releases smoothly and rotates correctly.
- Inspect the Gap: Check the gap between the cylinder release lever and the frame. It should be minimal, allowing the lever to move freely without excessive play.
- Secure the Screw: Once the cylinder release operates smoothly, tighten the retaining screw securely to lock the adjustment in place.
| Adjustment | Effect |
|---|---|
| Tighten Screw | Decrease gap, reduces cylinder play |
| Loosen Screw | Increase gap, increases cylinder play |
Follow these steps precisely to ensure that the cylinder release system is installed and adjusted correctly, maximizing the performance and reliability of your race revolver.
Modifying the Hammer and Trigger
The next step involves modifying the hammer and trigger to create a lighter and smoother pull. This can be achieved by carefully filing away a portion of the metal on the hammer that engages with the sear. This should be done gradually, while testing the trigger pull at regular intervals to ensure that the pistol is still functioning correctly.
Adjusting the Trigger Spring
The trigger spring is a crucial component that influences the pull weight of the trigger. To reduce the pull weight, you can either replace the existing spring with a lighter one or adjust the existing spring by stretching it slightly. Stretching the spring should be done carefully to avoid weakening it excessively.
| Old Spring | New Spring |
|---|---|

Polishing the Trigger Surface
Polishing the trigger surface can further reduce friction and improve the smoothness of the trigger pull. This can be done using a fine abrasive paper or stone, taking care not to remove too much material or change the trigger’s geometry.
Once you have completed these modifications, you should have a race revolver with a significantly smoother and lighter trigger pull that will allow for more accurate and precise shooting.
Fitting the Ejector Rod and Ejector
Ejector Rod
Slide the ejector rod into its hole in the frame. If the rod is too tight, carefully file or sand the rod until it fits smoothly. If the rod is too loose, you can shim it with a thin piece of paper or metal.
Ejector
The ejector is a small, spring-loaded plunger that fits into the rear of the cylinder. It engages with the extractor star to push the spent cartridges out of the cylinder. To install the ejector, insert it into the rear of the cylinder and push it into place. The spring will hold it in place.
Extractor Star
The extractor star is a star-shaped part that rotates inside the cylinder. It engages with the cartridge rims to extract the spent cartridges. To install the extractor star, insert it into the cylinder and rotate it until it snaps into place.
Pawl and Spring
The pawl is a small, spring-loaded lever that engages with the extractor star to prevent it from rotating backwards. To install the pawl, insert it into the frame and push it into place. The spring will hold it in place.
Cylinder Base Plate
The cylinder base plate is a small, round plate that fits onto the rear of the cylinder. It holds the ejector and extractor star in place. To install the cylinder base plate, place it on the rear of the cylinder and press it into place. The springs will hold it in place.
| Part | Description |
|---|---|
| Ejector Rod | Slides into the frame and pushes the ejector into the cylinder. |
| Ejector | Spring-loaded plunger that engages with the extractor star to push the spent cartridges out of the cylinder. |
| Extractor Star | Star-shaped part that rotates inside the cylinder and engages with the cartridge rims to extract the spent cartridges. |
| Pawl and Spring | Lever that engages with the extractor star to prevent it from rotating backwards. |
| Cylinder Base Plate | Small, round plate that fits onto the rear of the cylinder and holds the ejector and extractor star in place. |
Configuring the Mainspring and Trigger Return Spring
Carefully select the spring rates and configuration to suit your desired trigger feel and performance. Experiment with different springs to achieve the optimal balance between trigger pull weight, reset, and follow-through.
Mainspring
The mainspring serves two important functions: to rotate the cylinder and to reset after firing. Choose a mainspring that is strong enough to reliably rotate the cylinder, but not so strong that it creates excessive trigger pull weight.
Trigger Return Spring
The trigger return spring plays a crucial role in the smooth and consistent operation of the trigger. Experiment with different spring tensions to achieve a trigger reset that is both positive and fast. A heavier spring will result in a faster reset, while a lighter spring will provide a slower reset.
| Spring Rate (lbs) | Trigger Pull Weight (lbs) | Trigger Reset (ms) |
|---|---|---|
| 15 | 4-6 | 15-20 |
| 17 | 5-7 | 12-17 |
| 19 | 6-8 | 10-15 |
Remember, these settings are a starting point, and may need to be fine-tuned based on the specific revolver, your shooting style, and personal preferences.
Adjusting the Hammer and Trigger Timing
The next step is to adjust the hammer and trigger timing. This ensures that the hammer falls at the correct time when the trigger is pulled. Here are the steps to adjust the timing:
1. Remove the sideplate and hammer spring
Start by removing the sideplate and hammer spring. This will allow you to access the hammer and trigger.
2. Cock the hammer
Next, cock the hammer. This will bring the hammer to the rearmost position.
3. Adjust the hammer-trigger engagement
Now, adjust the hammer-trigger engagement. The hammer should engage with the trigger when the trigger is pulled halfway back.
4. Adjust the trigger overtravel
After you have adjusted the hammer-trigger engagement, adjust the trigger overtravel. The trigger should stop moving rearward when it is fully pulled back.
5. Reinstall the sideplate and hammer spring
Once you have adjusted the timing, reinstall the sideplate and hammer spring. Make sure that the sideplate is tightened securely.
6. Check the timing
Finally, check the timing by dry-firing the revolver. The hammer should fall at the correct time when the trigger is pulled.
7. Troubleshooting
