Sig Sauer P320 XF 4.7" 17-Round 9mm Pistol in Black - Model 320XF-9-BXR3P-R2

The Sig Sauer P320 XF is a full-size duty and competition 9mm pistol built on Sig's modular platform and engineered for shooters who demand precision, reliability, and tactical flexibility. The 4.7" barrel delivers a 6.6" sight radius—ideal for accuracy at distance—while the optics-ready slide accepts Romeo1Pro, Delta Point Pro, and RMR-pattern red dots, giving you the option to mount a modern sight without gunsmithing. This is the gun for serious handgun competitors, dedicated sport shooters, and professionals who want a modern platform with proven performance.

The XSeries grip module is where the XF earns its reputation. An extended beavertail and high undercut trigger guard reduce muzzle flip and support a high, secure grip—crucial for rapid follow-ups and flat shooting. The integrated magwell funnels rounds into the magazine smoothly under stress. Paired with the XSeries flat trigger, you get a clean, predictable break that rewards good technique and speed.

Sights and controls are purpose-built. X-Ray3 day/night sights give you fast target acquisition in any light, while the striker-fired action runs clean and simple. The stainless steel slide and frame, finished in Nitron, handle hard use and corrosion. Two 17-round steel magazines come in the box, giving you serious round count for training, competition, or duty carry. At 8.2" overall and 29.6 oz loaded, it's a full-size platform that handles like a modern service pistol.

The P320 XF is not the smallest gun in Sig's line, but it's built for shooters who value control, accuracy, and the flexibility to run iron sights, a red dot, or both. Whether you're prepping for an IPSC stage, maintaining duty-grade skills, or simply want a no-compromise 9mm that shoots where you point it, the XF delivers.
