In a double-action system, the trigger pull both cocks and releases the hammer, requiring the sear to manage significantly more energy and travel. A well-cut sear will have a smooth, consistent angle that allows the hammer to fall cleanly without binding or stacking.
How the Sear Mechanism Works Inside a Gun
Understanding this small but vital component is essential for anyone who wants to grasp how a gun functions safely and reliably, as it directly influences the timing and safety of the discharge. 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.
The trigger, connected to the trigger bar, applies pressure against the sear, gradually overcoming the holding force. This interaction creates a locking mechanism that prevents the hammer from moving forward under the force of its own spring.
Understanding the Sear Mechanism Inside a Trigger System
A correctly functioning sear ensures that the weapon will only fire when the trigger is deliberately pulled to the end of its travel. The Mechanics of the Sear The mechanics of a sear operate on a principle of leverage and interference.
