The Johnny Custom Glocks Evolution X EDC Trigger System is a hand-tuned upgrade built from Glock OEM components for shooters who want a cleaner, more predictable trigger in their 9mm Generation 4 Glock pistols. The refined trigger bar and reworked connector create a defined wall with a crisp 3.5–4.5 lb break, shortened pre-travel, and zero over-travel, all while maintaining Glock’s familiar feel and reliability.

This drop-in system is configured specifically for Gen 4 9mm Glock frames and includes Glock OEM spec trigger, trigger housing, and trigger bar, plus 4.5 lb and 5 lb striker springs and a safety plunger with reduced power spring. Ideal for defensive-focused range work, training, and everyday carry setups where consistency and control matter, it delivers a smoother press and faster reset without compromising safety. Johnny Custom Glocks’ attention to detail and craftsmanship is evident in the precise tuning and thoughtful spring options included in the kit.
