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.

Disclaimer

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.

From Grayguns, a Master Spring Set for Sig Sauer P-Series handguns. The P-MSS kit is an action upgrade package designed to reduce trigger pull weight while still providing reliable primer strikes. This set includes two mainsprings, one 17 lb. and one 19 lb., and a competition sear spring.

Fits the modern P-Series handguns with a DA/SA system, P220, P224, P225A1, P226, P227, P228, P229 and P-226 X-Five Allround.

The SIG P-Series Dual Adjustable Straight Trigger is the straight-faced version of our legendary curved P-Series Dual Adjustable Trigger. This trigger includes over travel and pre-travel adjustability. (Adjustable for double action slack and single action over travel.)

The optimized trigger face pressure-wall angle provides for outstanding single action sear release and positive, ultra-fast reset control. The ergonomics provides superior double action leverage and control.

Dual Adjustable Straight Trigger Details

This trigger is machined from tough steel. The trigger is carefully heat treated and finished in black oxide. Tight pin hole tolerances assure smooth, solid function. Guaranteed for life against defects in materials or workmanship.

Made with love, supplied with a hex key.

The trigger weight is about .83 ounces (23.45 grams)

Fit Guide

The trigger is designed to fit both current and older model traditional double action (DA/SA/decocker) P-Series pistols, including

• X5 All-Round
• P220 (see exceptions below)
• P226
• P228
• P229
• P227 and others

These triggers are approximately 10mm wide. At this time, we are not suggesting this trigger for guns equipped with the DAK trigger system.

This trigger may not be fully compatible with California compliant or similar P-series pistol models equipped with a magazine disconnector, and Grayguns urges caution. We do not recommend deactivating any mechanical safety device.

The Grayguns DA/SA triggers will not fit SIG Pro, P225 / P6, P239, West German P220s, or most SAO models. Most of these triggers are a narrower 8mm width

Intended to be installed by a qualified Sig Sauer armorer or gunsmith

Developed by the renowned gunsmiths of Grayguns, the FAT guide rods are designed to optimally support factory Sig Sauer, and Grayguns custom multi-strand springs for maximum service life and smooth, reliable function.
