Single Action vs. Double Action: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 13, 2024
Single action is a firearm mechanism where the trigger performs one action, typically releasing the hammer. Double action is a firearm mechanism where the trigger performs two actions, cocking and releasing the hammer.

Key Differences

Single action firearms require manual cocking of the hammer before each shot, making the trigger pull lighter and often more precise. Double action firearms allow pulling the trigger to both cock and release the hammer, offering quicker successive shots. Both mechanisms are found in various types of handguns.

In single action, the trigger's sole function is to release the hammer or striker. In contrast, double action triggers first cock the hammer and then release it in a single pull. Both systems have distinct advantages in terms of speed and accuracy.

Single action firearms are often favored for target shooting due to their light and crisp trigger pull. Double action firearms are commonly used for self-defense because of their ability to fire immediately without manual cocking. Both types require different levels of skill and training.

Maintenance of single action firearms typically involves fewer moving parts compared to double action, potentially leading to greater reliability and longevity. Double action firearms, however, offer the advantage of a quicker response in emergency situations. Both designs reflect different priorities in firearm engineering.

Single action mechanisms are commonly seen in older and classic firearm models. Modern handguns more frequently utilize double action mechanisms or a combination of both (double action/single action). Each type provides unique benefits depending on the intended use of the firearm.
