The P-Series Adjustable Intermediate Curved Trigger adds over-travel adjustability to our original design. Utterly indestructible, the trigger is machined from tough steel, carefully heat treated and finished in black oxide. Tight pin hole tolerances assure smooth, solid function.

Our intermediate trigger shape optimizes both SA and DA control for optimal control, and is more comfortable than the factory short trigger it replaces. Guaranteed for life against defects in materials or workmanship.

Made with love, supplied with a hex key.

Fit Guide

The 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.


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.
