The LANTAC Ultimate Spring Kit features springs which are manufactured from the highest grade piano wire and tempered for the best service life. Each spring is calibrated to deliver consistent force through the entire compression cycle for reliable operation every time the pistol is fired. With nearly 30% more power the trigger spring actually reduces the pull weight by as much as 1lb. The lower power firing pin safety spring reduces friction caused by the firing pin plunger engaging with the trigger bar and creates a much smoother operation of the parts.
Different weight springs are designed for a specific purpose. The 4.0lb Firing Pin Springs are designed for target, competition and sporting use. The 6.0lb Firing Pin Springs are designed for carry and self-defense use. Finally, the 6.5lb Firing Pin Springs are designed for maximum reliability.
