What is a Double Action Revolver?
A double action revolver is a type of handgun that allows the user to fire a round with a single pull of the trigger, without the need to manually cock the hammer or trigger. This is in contrast to single action revolvers, which require the user to manually cock the hammer or trigger before firing.
How Does a Double Action Revolver Work?
A double action revolver works by using a combination of internal mechanisms to both cock and fire the revolver. When the trigger is pulled, the sear is released, allowing the hammer to fall and strike the primer of the cartridge. At the same time, the trigger also pulls the hammer back to the cocked position, ready to fire again.
Types of Double Action Revolvers
There are several types of double action revolvers, including:
- Double Action Only (DAO): These revolvers can only be fired in double action mode, and do not have a manual safety or decocking lever.
- Double Action/Single Action (DA/SA): These revolvers can be fired in both double action and single action modes. The user can choose to cock the hammer manually and fire in single action mode, or use the double action trigger to fire without cocking the hammer.
- Striker-Fired: These revolvers use a striker instead of a hammer to strike the primer of the cartridge. They are often used in modern self-defense revolvers.
Advantages of Double Action Revolvers
Double action revolvers have several advantages over single action revolvers, including:
- Faster Firing: Double action revolvers allow the user to fire multiple shots quickly, without the need to manually cock the hammer between shots.
- Easier to Use: Double action revolvers are often easier to use for beginners, as they do not require the user to manually cock the hammer or trigger.
- Increased Safety: Double action revolvers often have a manual safety or decocking lever, which can help prevent accidental discharges.
Disadvantages of Double Action Revolvers
Double action revolvers also have several disadvantages, including:
- Less Accurate: Double action revolvers can be less accurate than single action revolvers, as the trigger pull can be heavier and less consistent.
- More Complex: Double action revolvers are often more complex and have more moving parts than single action revolvers, which can make them more prone to malfunction.
- Less Customizable: Double action revolvers often have less customization options than single action revolvers, as the internal mechanisms are designed to work together to fire the revolver.

| Firing Mechanism | Striker or hammer | Hammer |
| Accuracy | Less accurate | More accurate |
| Complexity | More complex | Less complex |
| Customization | Less customizable | More customizable |
Conclusion
In conclusion, a double action revolver is a type of handgun that allows the user to fire a round with a single pull of the trigger, without the need to manually cock the hammer or trigger. Double action revolvers have several advantages, including faster firing and increased safety, but also have several disadvantages, including less accuracy and more complexity. When choosing a revolver, it is important to consider the type of shooting you will be doing and the level of customization you need.
