The Johnny Custom Glocks Evolution X EDC Trigger System for 9mm Slimline pistols is a hand-tuned upgrade built from Glock OEM components for shooters who want a cleaner, more predictable trigger. Designed specifically for the Glock 43, 43X, and 48, this system uses the OEM serrated Slimline trigger shoe and a carefully reworked connector to deliver a defined wall and a crisp break in the 3.5–4.5 lb range.

This drop-in kit is ideal for defensive-focused pistols and regular range use where consistency and reliability matter. With pre-travel reduced to approximately 1/8", zero over-travel, and a short, fast reset, it supports accurate shot placement and efficient follow-up shots without compromising the familiar Glock feel. Johnny Custom Glocks’ attention to detail and tuning expertise are evident in the smoothed, de-burred trigger bar and thoughtfully selected springs that complete the system.
