SIG Sauer 320X510BXR3R210 P320 10M Pistol

The SIG P320 XTEN in 10mm Auto represents a purpose-built powerhouse for serious shooters, law enforcement professionals, and hunters who demand precision and stopping power in a modular platform. This model combines the proven reliability of SIG's P320 family with the velocity and terminal performance of 10mm cartridge, delivering a modern tactical handgun engineered for duty, sport, and field applications. The XTEN is a direct evolution of the X-series, bringing enterprise-grade ergonomics and optic compatibility to a caliber traditionally reserved for specialized roles.

Built around a robust 5-inch bull barrel, the P320 XTEN delivers superior sight radius, barrel dwell time, and velocity consistency compared to shorter configurations—critical factors for accuracy at extended ranges and consistent ballistics across ammunition variants. The X-optic-ready slide accommodates modern reflex sights without adapters, while the XRAY3 day/night sights provide redundant aiming solutions in low-light and no-light environments. The striker-fired action offers consistent trigger geometry and a crisp break, while the modular fire control group and serialized chassis allow seamless platform interchangeability—a defining feature that has made the P320 the preferred choice of military and law enforcement globally.

This 10mm variant is optimal for shooters managing multiple threats, pursuing large game, or training at distance where sustained accuracy matters more than magazine capacity. The generous 3.69-pound weight aids recoil mitigation in a caliber known for sharp impulse, while the 5-10 round magazine configuration (likely standard XTEN capacity) balances maneuverability with adequate ammunition onboard. Field operators and competitive shooters benefit from the optic-ready slide's native mounting footprint, eliminating adapter failure points and zeroing inconsistencies. The P320 XTEN integrates with existing P320 grip modules, allowing users to customize ergonomics and carry angle to match mission requirements or hand geometry.
