SIG SAUER P211-GT4 9MM LUGER SEMI-AUTO HANDGUN W/ROMEO-X SIG-LOC™ PRO

Designed for carry without compromise, the SIG SAUER P211-GT4 delivers duty-grade performance in a refined, compact-length, non-compensated configuration. Built on the proven P211 platform, the GT4 balances concealability, control, and reliability for shooters who demand performance in a carry-ready form factor.

Chambered in 9MM, the P211-GT4 features a 4.2” target-crowned bull barrel paired with a carry-length SIG-LOC™ PRO optic-ready slide. This traditional slide configuration offers predictable recoil characteristics, excellent accuracy, and seamless integration with modern pistol optics—without the added length of a full-size slide.

Aggressive, duty-style serrations ensure confident manipulation in all conditions, while fully ambidextrous controls support intuitive operation for both right- and left-handed shooters. A steel frame with a carry-length Picatinny accessory rail and three-slot accessory rail provides durability and versatility, while the precision-engineered alloy grip module with G10 grip panels delivers a secure, consistent grip.

Performance is further enhanced by a straight-pull, skeletonized flat blade trigger for a clean, repeatable break, and a removable low-profile steel magwell that improves reload efficiency without compromising concealability.

ROMEO-X SIG-LOC PRO

The SIG-LOC™ (Leverage Optimized Connection) system was first concepted during the development of the ROMEO-M17, revolutionizing pistol-mounted optic integration with a low-profile, ultra-tough connection between the optic and pistol slide. Designed for precision and strength, SIG-LOC™ ushers in a new era of expectation and performance for civilians and professionals with the ROMEO-X SIG-LOC pistol-mounted red dot. SIG-LOC™ is an innovative mounting footprint that establishes five points of contact between the slide and optic to eliminate shift in zero created by extensive shock from recoil and harsh impacts. The unique bottom-mounted design allows for a longer focal length that dramatically reduces parallax and reticle distortion to provide an incredibly forgiving shooting experience. With SIG-LOC™, you’re investing in technology that has been vetted and trusted by the most demanding users in the world, ensuring superior accuracy and reliability in every situation. Pistol slides that are configured with SIG-LOC mounting footprints are still fully compatible with traditional top-mount reflex sights.
