Step into the next generation of precision handguns with the SIG SAUER P211 GTO. Built on a full-size serialized fire control unit and engineered for shooters who demand speed, repeatable accuracy, and optic-first performance, the P211 GTO ships factory-ready with a ROMEO-X red dot and XRAY3 day/night sights — out of the box optics, out of the box capability.

This 9mm full-size pistol pairs a 4.4″ bull barrel and MACH3D compensator with a flat-faced XSeries trigger and a modular Nitron-finished frame for a stable, controllable shooting platform. Ergonomically refined and built to handle high-capacity use, the P211 GTO includes one 23-round and two 21-round P320-compatible steel magazines so you’re ready for rapid strings right away.
