The Grayguns P-Series Dual Adjustable Curved Trigger is the ultimate trigger upgrade for your Legion Series or any modern DA/SA SIG P-Series pistol.

Bruce Gray has combined the adjustable over-travel feature, unbeatable comfort and control and unrivaled quality of our original OEM SIG Sauer® Legion P22xCT, Classic Standard trigger, with the improved geometry and pre-travel adjustment of our wildly popular P22xST Dual Adjustable Straight Trigger series.

This trigger is the ultimate upgrade for your Legion Series or any modern DA/SA SIG P-Series pistol.

This steel trigger is carefully heat treated and finished in black oxide or Nickel Teflon® PTFE. Occasionally the trigger will be available in Cerakote colors. Tight pin hole tolerances assure smooth, solid function. The trigger is guaranteed for life against defects in materials or workmanship.

Included in the package is a hex key for adjusting pre-travel and over-travel.

Trigger Finishes

Black Oxide

  • Standard blued finish

Titanium Nitride (TiN)

A well-proven standard layer type through its balanced properties. The golden titanium nitride layer, abbreviated TiN, indicates the following properties:

  • High hardness and adhesion
  • Good chemical resistance
  • Good temperature resistance in air
  • Relatively low thermal conductivity
  • Attractive, golden color

Titanium Carbo-Nitride (TiCN) (Copper)
The TiCN Copper finish features high hardness, low residual stress, good abrasive wear resistance, and high reliability in dry operations.

Physical Vapor Deposition (PVD)

This state-of-the-art process creates a molecular bond to the trigger, resulting in a durable finish. The PVD finish should not rust, discolor or tarnish.

Nickel PTFE

Electroless Nickel PTFE (Teflon®) is an advanced, self-lubricating, composite coating with PTFE particles co-deposited in the electroless nickel layer. Provides a hard, uniform, self-lubricating coating for our premium aftermarket triggers.

Dual Adjustable Curved Trigger Fit Guide

This 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.

The trigger is not compatible with our trigger bars included with the Enhanced Leverage System.

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.

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
