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.

SAO Straight Trigger Details

The SAO trigger is machined from solid steel. The trigger is carefully heat treated and finished in black oxide. Tight pin hole tolerances assure smooth, solid function. The trigger is 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 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.

    Quick and easy install, outstanding fit and function

    I installed the GG straight adjustable SAO into my SAO Elite P226 replacing the factory curved trigger. The job was quick and painless, and the results were excellent. I made a slight adjustment to the take up, and left the reset alone (it’s already as good as can be on this particular piece). The feel matches that on my Legion P229. Build quality was outstanding with a strong pin and excellent machining. Super comfortable for rapid fire with no hotspots. I saw a slight improvement in my hammer splits, from .16-18 to .14-16.

    I also had outstanding service, with the part arriving in just a few days, and before ordering I got good support from customer service to ensure I was ordering the right part.

    I’ve always enjoyed exceptional service from GG and this was no exception.

    Better feel and more consistent smaller groups.

    I hesitated for a while before finally deciding to get this trigger, and I’m so glad I got it! Immediately noticeable is that the face of the trigger is flat as well as being straight (in contrast to the Sig Legion SAO trigger just being straight but having a rounded face) which gives a much more consistent pull straight back with much less tendency to push the sights off target left or right depending on finger position. My groups are almost half the size, and my inconsistency is pretty much gone.

    What’s funny is that I originally ordered this to reduce the take up, and that’s nice and as expected, but the biggest benefit is the much more consistent shooting. Would unequivocally recommend, and buy again. Install was a breeze too.

    Shipping was immediate from GG, and my shopping experience was flawless to boot!
