SIG Sauer P211 GTO Equinox | 9mm | 4.4" Comp | Optic Ready | 23rd Pistol

The SIG Sauer P211 GTO Equinox (MPN: 211F-9-GTO-EQ) is a compensated, single-action 9mm built on SIG’s steel-frame P211 architecture and finished in the distinctive Equinox treatment. It combines a 4.4-inch bull barrel with the MACH3D compensator, alloy grip module, G10 grip panels, and P320-compatible magazines in a competition-oriented full-size package.

The P211 GTO uses a stainless-steel frame, removable alloy grip module, skeletonized flat-blade trigger, ambidextrous manual controls, and removable steel magwell. Its SIG-LOC PRO optic-ready slide supports compatible optics while retaining the factory fiber-optic front and black rear sights. This Equinox configuration is listed with one 23-round and two 21-round steel magazines.
