Sig Sauer P320 | 9mm | Romeo-X PRO | 17rd Pistol

The SIG Sauer P320 XFull 9mm pistol combined with the factory-installed ROMEO-X PRO red dot sight represents the pinnacle of modern, optics-ready duty firearms. Engineered to deliver match-grade accuracy and rugged reliability, this full-sized package gives you maximum capability right out of the box, whether for home defense, duty carry, or competitive shooting.

By pairing the enhanced ergonomics of the XSeries frame with a premium, low-profile reflex sight, SIG Sauer offers a completely integrated tactical solution that allows for instantaneous target acquisition and absolute confidence in any environment.

Redefining Ergonomics with the XSeries Grip

At the heart of this firearm's shootability is the specialized XSeries full-size grip module. Designed to give shooters a more secure, intuitive purchase on the gun, it reengineers the standard profile to maximize control over heavy strings of fire.

• Extended Beavertail: A deep, undercut beavertail allows your hand to sit much higher and closer to the bore axis, dramatically reducing muzzle flip and felt recoil.

• Straight Trigger Profile: Features the flat-faced XSeries trigger, which provides a crisp, clean 90-degree break and a tactile reset for faster, more precise follow-up shots.

• Flared Magwell Compatibility: The grip profile features a subtly flared entrance to guide rapid, high-stress reloads without adding excess bulk to your holster footprint.

Co-Witness Ready ROMEO-X PRO Reflex Sight

This model comes pre-equipped with the robust ROMEO-X PRO red dot, built from durable 7075 aluminum to withstand the punishing slide forces of daily duty use.

• Ultra-Low Deck Height: The optic features an incredibly low profile, allowing you to seamlessly co-witness the red dot with the included standard-height XRay3 day/night sights. No extra-tall suppressor sights required.

• Side-Loading Battery: A side-mounted battery compartment allows you to swap power cells without ever needing to remove the optic or re-zero your handgun.

• Motion Activated Illumination: Utilizing advanced power management, the optic automatically powers up when it senses movement and sleeps during periods of inactivity to stretch battery life to its absolute limit.

Striker-Fired Versatility and Modular Safety

Built on the famous modular P320 platform, this pistol utilizes a stainless steel internal fire control unit, meaning the serialization stays with the chassis rather than the frame. The Nitron-coated slide features aggressive front and rear cocking serrations, making it easy to manipulate the action under any conditions or while wearing tactical gloves. With its full 4.7-inch barrel maximizing 9mm velocities and a generous 17-round capacity on tap, this setup provides a rock-solid, duty-ready platform that is ready to perform from day one.
