CZ 457 Performance Trigger

Description

CZ 457 Performance Trigger

The SIDHE CZ 457 Performance Trigger is engineered for shooters who want a clean, predictable break with a wide adjustment range. It ships as a two stage trigger with a defined first stage and a crisp second stage, and can be configured as a single stage trigger through sear‑engagement adjustment.

All critical components are wire‑EDM machined for precision and longevity. The body is manufactured from anodized ERGAL 7075, while the upper lever is produced from hardened 1.2083 steel with a DLC coating for minimal friction and consistent performance. The trigger blade is fully adjustable to optimize ergonomics for different shooting positions.
