Boost trigger responsiveness and reset strength with the ISMI +50% Power Trigger Return Spring for Glock Gen 5 pistols. Engineered for shooters who demand more; precision-manufactured from certified chrome silicon, this aerospace-grade alloy delivers 10x the service life of OEM music wire springs.

Each spring is heat treated, shot-peened, and stress-relieved to ensure maximum durability and consistent performance under pressure. The increased power improves trigger return speed; ideal for competition, defensive use, or any build where faster follow-up shots matter. Unlike OEM springs, ISMI’s chrome silicon holds tighter tolerances under stress and resists fatigue far longer. You’ll get more load, longer life, and less break-in time  right out of the box!

Features:

• +50% increased trigger return power for faster reset.
• Chrome silicon construction, 10x longer lifespan than OEM.
• Heat treated, shot-peened, and stress-relieved for max durability.
• Improves cycling consistency and trigger feel.
• Minimal break-in compared to OEM springs.
• Made in the USA.
