The Lantac USA Glock Spring Upgrade Kit comes with a 4 pound firing pin spring, 6 pound increased power trigger spring, and a reduced power firing pin safety spring. This kit helps to smooth out and reduce the overall pull weight of your factory Glock trigger and is compatible with all generations of G17/19 and other models that use the same style of springs. Each spring is made from high quality piano wire, tempered, and calibrated for a long high-performance service life. The combination of firing pin and trigger spring are what help to reduce the pull weight by about a pound while still retaining reliable function. The firing pin safety spring reduces friction caused by the trigger bar interacting with the safety and results an a much smoother trigger pull. This 4lb model is a great for a strictly target or competition gun.
