SIG Sauer® P211 GTO EQUINOX Pistol – 9×19

The SIG Sauer^® P211 GTO EQUINOX in 9×19 represents a premium performance platform developed by SIG Custom Works. Built around the P211 metal-frame architecture, it combines a 4.4-inch bull barrel with an integrated MACH3D compensator to reduce muzzle rise and perceived recoil. Polished stainless steel slide accents contrast with E-Nickel controls, creating the distinctive two-tone EQUINOX aesthetic. The GTO EQUINOX is engineered for speed, control, and refined craftsmanship.

4.4" Bull Barrel and MACH3D Compensator

The pistol features a 4.4-inch bull barrel paired with an integrated MACH3D compensator. The compensator is engineered to optimize gas flow, mitigating muzzle rise and reducing perceived recoil. The result is improved shot-to-shot recovery and enhanced stability during rapid fire sequences.

SIG-LOC PRO Optics Interface

The slide is optics-ready via the SIG-LOC PRO mounting interface, allowing secure installation of compatible red dot sights. Deep slide serrations provide positive manipulation under demanding conditions. The pistol is equipped with an ambidextrous slide catch and a reversible magazine release for enhanced user adaptability.

EQUINOX Two-Tone Finish and Premium Materials

The EQUINOX configuration features polished stainless steel surfaces on the slide and compensator, complemented by E-Nickel finished controls. Custom Alloy LOK grip panels with GridLOK texture provide a secure, competition-oriented grip surface while enhancing the distinctive appearance of the platform.

Single Action Only (SAO) Trigger System

The flat, skeletonized Single Action Only (SAO) trigger delivers a crisp break and short, precise reset optimized for performance shooting. The pistol incorporates a manual thumb safety that mechanically blocks the trigger mechanism when engaged.

Sights and Magazine Configuration

The pistol is equipped with a fiber optic front sight and a blacked-out rear sight for rapid target acquisition. The P211 GTO EQUINOX utilizes steel magazines compatible with the P320 platform. The package includes one 23-round and two 21-round magazines, supporting competition and range applications where capacity and control are critical.
