In this video we provide an educational overview and detailed, step-by-step guide to installing a Glock Trigger Spring Kit (Gen 1–5, except Glock 42/43) and polishing key contact surfaces. The goal is to help responsible, law-abiding Glock owners achieve a smoother, lighter, and more consistent trigger pull using drop-in springs and basic polishing techniques.

About the Glock Trigger Spring Kit (Gen 1–5, except G42/G43):
- Fits all Glock Gen 1–5 models (EXCEPT Glock 42 and 43)
- Includes:
- 4 lb reduced-power firing pin spring
- 5 lb reduced-power firing pin spring
- 6 lb increased-power firing pin spring (factory is ~5.5 lb)
- Extra-power 6 lb trigger spring (extra power helps reduce felt trigger pull)
- Reduced-power firing pin safety spring
- Springs are designed to let you tune trigger pull weight and feel:
- Extra-power trigger spring can reduce pull by up to ~1 lb and speed up reset
- Reduced-power firing pin safety spring lowers friction at the firing pin safety
- Multiple firing pin spring weights allow you to balance pull weight and reliability
- All springs are American-made from high-quality spring steel for long-term durability
What This Video Covers:
