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.

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.

    This trigger is awesome. The nickel finish is super slick and figment is just like the original. The double action take up is totally gone with the over travel dialed in, the reset is insanely short and positive (I already had an SRT kit in the gun). Installation is simple; if you have done any gun work on berettas or smith autos, it is no more complex than those guns. Combined with the hammer strut kit, this is a game changer

    She may look stock but she isn't

    This P-229 is my edc and the only stock internals are the slide release and decocker. Currently installed is this trigger, the SIG P-Series Fat Custom Strut System, Grayguns Short Reset Trigger (SRT) Kit and the SIG P-Series Master Spring Set. I have a consistent 8 pound DA trigger weight and a 4 pound SA trigger weight. The best thing is the double action pull is so smooth that it’s as if the trigger is running on rails. When adjusted properly there is no slop with either the DA or SA pull and I found that adjusting the pre travel went best with the locking plate removed. Since the plate was removed I went ahead and adjusted over travel at the same time. The pistol was already a tac driver however she runs smooth as silk. Mr. Gray has hit this out of the park.

    Amazing pistol NOW

    I ordered the PSat for my M11 and the results were so amazing after I installed it, I had to order one for ALL of my Sig pistols! It is as if I have all new pistols now. I never though a trigger could be so smooth on a factory weapon but I am glad to be proven wrong. Thanks Bruce for all that you do and for your designs and products. I can NOT say enough good praises for the triggers.

    Cut Down on Waste

    The GGI Dual Adjustable Trigger is an improvement over the highly regarded Sig Legion triggers which were of the P-SAIT design, and only dealt with “over travel”. This product, for the traditionalist, who likes a curved trigger will eliminate the “take up”, or trigger movement that takes up the “slack”, so when the trigger moves, so does the hammer. As with any firearm component, replacement needs to be tested for proper function, and settings “sealed”, with thread locker, to prevent movement by vibration. Minor clearances also need to be included with adjustments, to compensate for temperature variations, and possible fouling build up. I found the “take-up” was easiest accomplished with the Locking Insert removed, in half turn increments. The “over-travel” adjustments can be made with the Locking Insert in place. I normally degrease components before assembly, then use Loc-Tite 290 (Green) for assembled parts.

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.
