Sig Sauer P211-GTO Metal Frame 9mm SAO Pistol
4.4" Bull Barrel with MACH3D Comp & ROMEO-X SIG-LOC Compact Red Dot

The SIG SAUER P211-GTO redefines what a full-size performance pistol can be. Inspired by the timeless design of hammer-fired double-stack 1911s and infused with cutting-edge innovation, this firearm is engineered for shooters who demand elite-level precision and control.

At the heart of the P211-GTO is a 4.4” bull barrel paired with the revolutionary Mach3D compensator, precision-manufactured to reduce muzzle rise by up to 30%. The result? Faster follow-up shots, reduced felt recoil, and a smoother shooting experience. The pistol’s straight-pull trigger delivers a crisp 3.5–4 lb break, ensuring consistent accuracy with every pull.

Built on a robust stainless steel frame with a full-length dust cover and G10 grip panels, the P211-GTO offers superior balance, rigidity, and tactical aesthetics. It’s optic-ready slide mounted with a ROMEO-X SIG-LOC Compact Red Dot Optic, and comes equipped with three steel magazines—one 23-round and two 21-round—compatible with the proven P320 platform.
