The P211 GTO is built on a 2011-style platform with a hybrid construction: a stainless-steel mainframe for rigidity and an aluminum-alloy grip module for balance and handling. The entire pistol wears a Nitron black finish across the slide, frame, and receiver for a uniform, duty-ready appearance.
Its 4.4 in bull barrel is paired with a factory MACH3D 3D-printed compensator that includes a distinctive triangular front window. The slide has front and rear cocking serrations and two Torx-head screws on the top. Overall length is 8.5 in, height is 5.25 in, and unloaded weight is 45.9 oz.
This single-action-only, hammer-fired configuration includes a manual thumb safety, grip safety, and firing-pin safety. A skeletonized trigger and a removable flared magwell support fast, consistent control. The textured modular grip provides secure purchase.
Sighting is straightforward with iron sights: a green fiber-optic front and a plain black notch rear. The full-length dustcover integrates an accessory rail with three 1913-style slots. The pistol accepts SIG P320-pattern double-stack magazines and is rated at 23+1 capacity. Country of origin is the United States, and the manufacturer part number is 211F-9-GTO.
