SIG Sauer P320 XFull 9mm 17+1 4.7" Optic Ready Pistol

The SIG Sauer P320 XFull delivers enhanced accuracy and modularity in a full-size striker-fired platform. This 9mm pistol combines the proven P320 operating system with X-series upgrades for competitive shooting and professional applications.

What Makes This Different

The P320 XFull features a 4.7-inch carbon steel barrel that extends accuracy potential beyond standard compact models. The optic-ready slide accepts popular red dot sights without additional machining, while the serrated stainless steel construction provides superior corrosion resistance compared to standard carbon steel slides. The modular fire control unit allows caliber and frame size changes without purchasing a complete new firearm.

Key Features

• 17+1 capacity with flush-fit magazines for extended range sessions
• 4.7-inch carbon steel barrel with black nitron finish for durability
• Optic-ready slide cut compatible with Romeo1Pro and similar footprints
• Integrated Picatinny rail accommodates tactical lights and lasers
• XCarry medium polymer grip module with enhanced texture

The extended sight radius and balanced weight distribution contribute to consistent shot placement at extended distances. Competition shooters benefit from the crisp trigger break and minimal muzzle flip during rapid fire strings. The full-size frame provides a secure grip for shooters with larger hands while maintaining concealability for those who prefer full-size carry pistols. Weather-resistant finishes handle humid conditions and regular cleaning solvents without degradation.
