A correctly functioning sear ensures that the weapon will only fire when the trigger is deliberately pulled to the end of its travel. The angle and surface of the sear face determine how much force is required to pull the trigger.
How Sear Controls Affect Trigger Pull and Firearm Safety
The Impact on Safety and Reliability The sear is arguably the most important safety component in a firearm, acting as the final barrier between a loaded weapon and an accidental discharge. This wear can alter the trigger pull, making it lighter or, more dangerously, causing it to creep as the hammer begins to move before the trigger reaches the break point.
Consequently, the sear in a double-action revolver is built to be robust and is often adjustable to manage the increased stress and ensure a consistent, albeit longer, trigger pull. A well-cut sear will have a smooth, consistent angle that allows the hammer to fall cleanly without binding or stacking.

In contrast, traditional double-action revolvers rely on a complex sear mechanism that must simultaneously rotate the cylinder, cock the hammer, and hold it until the trigger pull aligns perfectly. Once the trigger reaches a specific point of resistance, known as the break, the sear is forced out of its notch, allowing the hammer to snap forward and ignite the primer.
