Our new P-Series Precision Dual Adjustable Straight Trigger (P-STR8) is the straight-faced version of our legendary curved Precision Adjustable Intermediate Trigger (P-SAIT) included in all SIG SAUER® Legion Series DA/SA pistols. Our straight version includes over travel and pre-travel adjustability. (Adjustable for double action slack and single action over travel.)
The optimized trigger face pressure-wall angle provides for outstanding single action sear release and positive, ultra-fast reset control. The ergonomics provides superior double action leverage and control.
Two Versions Available
P-STR8-S is available in two versions, machined from tough alloy steel or durable, lightweight 7075 Aluminum. (SIG SAUER Legion Series DA/SA pistols come with the curved, alloy steel version.) The steel version is carefully heat treated and finished in black oxide, while the Aluminum PSTR8-A is finished with black Type 3 hard-coat anodizing. Tight pin hole tolerances assure smooth, solid function. Both P-STR8 versions are guaranteed for life against defects in materials or workmanship.
Made with love, supplied with a hex key.
- Aluminum version is about .32 ounces (9.1 grams)
- Alloy Steel version is about .83 ounces (23.45 grams)
Grayguns triggers and internal components are approved for USPSA’s Production Division. See the updated Appendix D4. Updated Feb. 15, 2018. Sights, firing pins, firing pin retainers, pins, extractors, magazine releases, slide stops, thumb safeties, triggers, hammers, bushings, and ejectors MAY be replaced with OFM or aftermarket parts.
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.
