Bruce Gray combined the best of both worlds when he designed what we know as the hybrid trigger.

The unique face allows the shooter can take advantage of finger placement lower on the face, with the comfort of a traditional curved face. This hybrid design reduces trigger weight while preserving all mechanical safety values.

The Grayguns P320 Hybrid Trigger uses internal leverage changes to yield superior trigger pull, while supporting the voluntary upgrade’s enhanced reliability and rough handling performance qualities.

Includes our adjustable over-travel stop design to shorten reset and take out all gross over-travel. Designed for easy drop-in installation.

Specifically designed for P320s with current fire control unit components, or those who have gone through SIG’s Voluntary Upgrade Program.


Black Oxide

  • High hardness and adhesion
  • Good chemical resistance
  • Good temperature resistance in air

These parts are intended for installation by a qualified armourer or gunsmith. In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action. This is due to the varying tolerances present in all mass-produced firearms. Although kits fit with no issues in a great majority of pistols, Grayguns is unable to guarantee perfect functionality in every instance. Grayguns does offer installation services for all parts kits we offer.
