Overview

Built for Sig Sauer P320 pistols with the factory safety upgrade, this flat trigger is intended for shooters who want a lighter, more controlled trigger press without changing the pistol’s core safety values. It is also compatible with X-Series models, where it reduces pull weight by about 10% and shortens overall travel by 15%. Apex states that, when properly installed, the trigger can reduce pull weight by approximately 35% in factory upgraded models. It is not intended for non-factory upgraded P320 pistols or the Sig Sauer P250, so fitment should be verified before installation.

Considerations & Trade-offs

  • Designed for Sig Sauer P320 pistols with the factory safety upgrade; it is not intended for non-factory-upgraded P320 pistols.
  • It does not function in the Sig Sauer P250, so compatibility is limited to the specified P320 platforms.
  • The trigger is described as reducing pull weight and, in X-Series models, overall travel; that means the feel and setup will differ from the factory trigger and may not suit every shooter.
  • Proper installation is required for the stated performance and to maintain factory drop safety values.
