About this product
The Sig Sauer P226 X-Five STAS 9mm 5.0in Stainless SAO is a full-size precision pistol built for competitive shooters who demand repeatable accuracy and a crisp trigger break.

Key Features
- 5.0-inch bull barrel — The heavy barrel profile reduces muzzle flip and improves shot-to-shot consistency, critical for tight groups in USPSA or steel matches.
- Adjustable AX3 single-action trigger — You can dial in take-up, overtravel, and weight to your exact preference, delivering a clean break with minimal creep.
- X-Series optic-ready slide — Cut for popular red dot footprints, so you can mount an optic without sending the slide to a machine shop.
- Custom Hogue G10 Piranha grips — Aggressive texture locks your hand in place under recoil, even with sweaty palms or in wet conditions.
- Ambidextrous safety and three steel magazines — Lefties and righties get equal access, and the included spares mean less downtime reloading at the range.
Who It's For
This pistol is built for competitive shooters in USPSA, IDPA, or steel challenge who want a tuned trigger and bull-barrel accuracy straight from the factory. It also suits precision target shooters who prefer a single-action platform and don't need a double-action first shot. If you compete in Production or Carry Optics divisions, the optic-ready slide and adjustable trigger make it a strong contender.
Pros / Cons
- Pros: Fully adjustable trigger, bull barrel for accuracy, optic-ready slide, stainless steel frame for durability, includes three magazines.
- Cons: At 44 ounces unloaded, it's heavy for daily carry or long training sessions—this is a competition gun, not a concealed-carry piece.

FAQ
Does the P226 X-Five STAS come with optic mounting plates?
No, the slide is cut for direct mounting of common red dot footprints (e.g., RMR, Holosun K), but plates are not included. You'll need to purchase an adapter plate if your optic uses a different pattern.
Can this pistol be used for concealed carry?
Technically yes, but at 44 ounces and a 5.0-inch barrel, it's heavy and long. It's designed for competition and range use, not daily carry. Consider a lighter, compact model for concealed carry.
Is the trigger adjustable without tools?
No, the AX3 trigger requires a small Allen wrench for adjustments. The tool is not included, but any standard hex key set will work.
What magazines are compatible with the P226 X-Five STAS?
Standard Sig Sauer P226 9mm magazines work, including the included 17-round steel mags. Aftermarket options from Mec-Gar are also compatible.
