Sig Sauer P226 X-Five Nightmare is a full-size 9mm semi-auto pistol with a 5″ barrel and a 10-round capacity. It has a steel frame, a black Nitron finish, and a single-action-only trigger. Three magazines are included.
What makes it different
The trigger is the AX3 flat trigger system, and it is fully adjustable. That lets you tune the pull to your own preference. The XSeries slide is SIG-LOC optic-ready, so you can mount a red dot without a custom slide cut. It pairs with a bull barrel built for stability and precision.
The grips are Hogue G10 Nightmare panels with an integrated magwell. They have an aggressive texture and help guide the magazine in during reloads. The trigger and controls are E-Nickel, and the XSeries extended slide catch is easy to reach. The frame has a 1913 accessory rail, and XRAY3 Day/Night sights come on the slide. A manual safety is fitted.
This pistol suits shooters who like a full-size steel gun and a single-action trigger. Target work, range days, and competition are the natural fit. If you already train with a manual safety, the controls will feel familiar.
Good gear to pair with it includes a red dot sight for the optic-ready slide, a holster made for a full-size P226 with a 5″ barrel, extra 9mm magazines, and magazine pouches. Add range ammo, eye and ear protection, and a padded range bag.
