A firearm component allows for a two-part sequence before the weapon discharges. The first part typically involves taking up slack or reducing the pull weight, preparing the firing mechanism. The second part, requiring additional pressure, initiates the release of the hammer or striker, firing the round. As an example, consider a rifle used in precision shooting; the initial light pull preps the system, allowing the marksman to fine-tune their aim before the final, deliberate pull fires the shot.
This mechanism offers enhanced control and can contribute to improved accuracy, particularly in applications where precision is paramount. The design’s history is rooted in the pursuit of more consistent and predictable firing behavior, often seen as advantageous in target shooting and hunting scenarios. The reduced risk of accidental discharge during the initial pull is another frequently cited benefit.
