The P211 GTO pairs a 4.4 in bull barrel with Sig Sauer's factory MACH3D compensator to manage muzzle movement and keep the package compact. The slide is finished in Black Nitron and cut for the SIG-LOC PRO interface, with front and rear serrations for confident manipulation.
Capacity is 21+1 rounds, and the pistol uses SIG P320-pattern steel double-stack magazines. Three 21-round steel magazines are included, matching the pistol's double-stack layout and providing ample on-board ammunition.
The stainless steel frame wears a matching Black Nitron finish and a full-length dust cover with a three-slot accessory rail. A modular aluminum-alloy grip module with removable panels and textured G10 grip panels delivers a solid, repeatable hold.
Controls are fully ambidextrous, and safety elements include an ambidextrous manual thumb safety and a grip safety. The single-action-only fire control uses a flat-faced, skeletonized trigger and a skeletonized, commander-style hammer for a crisp break.
Sighting is straightforward and durable, with an installed front sight and an optic-ready slide; sight configuration may vary. Overall length is approximately 8.5 in, with an approximate weight of 45.4 oz. Made in the USA, this configuration is identified by mfg part number 211F-9-GTO-B-RXSL.
