The trigger, connected to the trigger bar, applies pressure against the sear, gradually overcoming the holding force. A correctly functioning sear ensures that the weapon will only fire when the trigger is deliberately pulled to the end of its travel.
Sear Function Explained Simply: How It Works and Why It Matters
Over time, the high-stress contact points of a sear will experience wear, particularly the contact angles and edges. The angle and surface of the sear face determine how much force is required to pull the trigger.
Conversely, a rough or damaged sear face can cause a heavy, gritty trigger pull or even prevent the hammer from releasing when the trigger is pulled, creating a dangerous malfunction that requires immediate attention. This allows for a very short and light trigger pull, ideal for precision shooting.

A well-cut sear will have a smooth, consistent angle that allows the hammer to fall cleanly without binding or stacking. 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.
