Sig Sauer® P211 GT4 Pistol / caliber 9x19 / ROMEO-X collimator

The P211 GT4 Sig Sauer pistol chambered in 9×19 offers a configuration built for both service deployment and everyday carry without compromise. It combines a 4.2" bull barrel with a classic slide profile in carry length and SIG-LOC PRO interface for optic mounting with the installed ROMEO-X red dot sight. The steel frame, aluminum grip module with G10 panels, and fully ambidextrous controls give the weapon a balanced and functional character. The GT4 focuses on predictable shooting behavior and robust construction.

4.2" Bull Barrel

The GT4 model uses a 4.2" bull barrel with a target crown. This configuration offers predictable recoil and stable accuracy while maintaining classic balance. The absence of a compensator preserves the traditional shooting character and structural simplicity.

SIG-LOC PRO and Duty Serrations

The carry-size slide is equipped with a SIG-LOC PRO interface for direct mounting of modern pistol optics. Aggressive duty-style serrations enable assured handling in challenging conditions. The slide's construction is suitable for service use and EDC for demanding users.

Construction and Controls

The foundation is a steel frame with a carry-length Picatinny rail sufficient for mounting most pistol lights. The aluminum grip module with G10 panels provides a firm and confident grip. The control elements are fully ambidextrous, allowing comfortable use for both right- and left-handed users. The model features a Single Action Only (SAO) trigger mechanism with a skeletonized flat trigger and manual safety.

ROMEO-X Red Dot Sight

The pistol is equipped with a ROMEO-X red dot sight designed for direct mounting on the SIG-LOC PRO interface. The optic uses a CNC-machined 7075 aluminum body, distortion-free aspherical lens, and MOTAC system with motion-activated illumination. Users can choose between a 2 MOA dot and a 32 MOA circle depending on the type of use. The low-height design allows retaining backup use of standard sights, and the side battery access simplifies replacement without needing to remove the red dot sight.

Magazines and Compatibility

The P211 GT4 uses steel magazines compatible with the P320. The platform is conceived as a universal solution for both service and sports use. It also includes a removable low-profile steel magwell that supports quick reloading without significantly increasing the weapon's outline. The gun features a skeletonized flat trigger with a direct and consistent action.
