Description
The LANTAC USA Ultimate Spring Set is a three-piece trigger upgrade kit built specifically for Glock 17 and Glock 19 pistols in Gen 1 through Gen 4 configurations. Designed around a 4 lb trigger pull target, this drop-in spring kit offers a measurable improvement over factory trigger feel without requiring any permanent modification to the pistol frame.
The kit includes a 4 lb firing pin spring, an increased-power 6 lb trigger spring, and a reduced-power firing pin safety spring. Together, the three springs work to take out creep, smooth the reset, and produce a cleaner break – the core of the LANTAC “Ultimate” trigger feel. Installation is straightforward and uses the existing factory spring locations inside the Glock frame, making this a popular first upgrade for shooters looking to refine the trigger of a duty, carry, or competition Glock.
Manufactured by LANTAC USA and built to drop directly into the Glock 17 and Glock 19 in Gen 1-4 variants with no fitting required, the Ultimate Spring Set (part 01-GP-4-USS) is a simple, reversible way to crisp up an otherwise stock pistol and is equally at home on a carry gun or a match build.
