The P-Series Single Action Only (SAO) Dual Adjustable Straight Trigger is the straight-faced, SAO version of our legendary SIG Legion triggers. This design includes over travel and pre-travel adjustability.

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

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 single action only P-Series pistols, including:

  • P220
  • P229
  • P226

These triggers are approximately 10mm wide. At this time, we are not suggesting this trigger for guns equipped with the older style 8mm wide trigger openings.

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.

This trigger will not fit SIG Pro, P225 / P6, P239, West German P220s. Most of these triggers are a narrower 8mm width.


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 guaranty perfect functionality in every instance. Grayguns does offer installation services for all parts kits we offer.
