The single-action revolver has been produced for generations, and is still a favorite among gun enthusiasts.
Traditional revolvers were made in single-action only. Single-action dictates that the hammer is cocked before the round can be fired. Tuning a revolver is a process that usually improves the revolver’s function by lightening or intensifying the trigger pull. All revolvers are made differently, and the tuning process will vary considerably.
1. Unload the weapon completely. Visually inspect the weapon to ensure that no live ammunition is present.
2. Disassemble your revolver. Consult your owners manual to perform this step.
3. Change out the trigger-return spring. A tuning kit will feature a variety of return springs. Choose the one that offers the best trigger return in terms of increase or decrease of trigger pull. Consult the owner’s manual for specific return-spring removal.
4. Adjust the trigger’s overtravel screw. The overtravel screw adjusts how far the trigger must travel before the return spring is engaged. Consult your owner’s manual for adjustment procedures to increase or decrease travel.
5. Check your barrel and the cylinder headspace using a headspace tool. The correct headspace will vary between revolvers, as will the diameter of the necessary headspace tool and the headspace adjustment process. Consult the owner’s manual for proper headspace procedures, and adjust accordingly.
6. Polish and clean all parts prior to reassembling your weapon. Clean, polished parts will allow for a smoother function and optimal shooting performance.
