The custom-designed Grayguns Short Reset Trigger (SRT) Kit incorporates SIG Sauer’s Safety Lever – with permission – and is designed to provide a smooth, short action reset in a drop in kit. The kit reduces the trigger reset travel by about 70 percent*, when using one of our dual adjustable triggers.

The really special part of this kit is the Bruce Gray designed custom sear. It is a bar-stock steel component, classically machined, painstakingly cut and inspected. The sear is hand-finished for the best angle of engagement and release with the factory hammer. The part is heat treated and stoned to provide a very smooth surface. We follow up with a baked-in nickel PTFE coating for a smooth release and outstanding durability.

User feedback indicates many shooters find their follow-up shots are quicker and more accurate with the Grayguns SRT Kit installed in their SIG DA/SA pistols. (See our Fit Guide below.)

Our Grayguns SRT Kit includes:

• Bruce Gray designed bar-stock custom sear
• SIG Sauer safety lever
• Two, 19 pound mainsprings*

Grayguns Short Reset Trigger Trigger Fit Guide

The Grayguns SRT Kit fits modern, SIG Sauer P-Series DA/SA pistols including: P220, P228, P229, P226, P226 X-Five Allround, P227 and most obsolete versions.

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.

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.

This trigger has a new over travel screw that can be adjusted to take out all of your wasted over travel.

Fit Guide

The Dual Adjustable Curved 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 exception 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.
