SIG Sauer Xten 10mm 5" 15-Round Stainless Pistol

The SIG SAUER P320 X-Ten in 10mm with 5-inch barrel is a full-size, striker-fired pistol engineered for shooters demanding superior stopping power and raw velocity in a modern duty platform. Built on the modular P320 platform with a polymer frame and Nitron-finished stainless slide, this 15-round 10mm semiautomatic delivers the ballistic performance of a potent cartridge without sacrificing pointability or control—a distinct advantage for operators and serious defensive users prioritizing penetration and terminal effect.

The 5-inch barrel maximizes chamber pressure and muzzle velocity inherent to the 10mm cartridge while maintaining a manageable overall length compatible with duty holsters and tactical rigs. Factory-installed X-ray3 night sights provide reliable low-light target acquisition, and the optics-ready slide features Trijicon RMR footprint mounting for red-dot integration—a critical capability for modern duty and competition workflows. The two included magazines provide 30 rounds of immediate duty load without requiring aftermarket carriers, and the modular frame accepts the full P320 ecosystem of grip modules for custom ergonomics.

This P320 X-Ten configuration serves law enforcement specialists, firearms instructors, competitive shooters, and civilian defensive users who have intentionally chosen 10mm over 9mm for its superior velocity, energy retention, and proven effectiveness on larger game and adversarial threats. The 10mm caliber demands respect and precision—this platform delivers both. At 4.5 pounds unloaded, the weight distribution of the full-size frame provides measurable recoil management, enabling faster follow-up accuracy compared to lighter compact frames in the same caliber. This is a purpose-built tool for those who understand ammunition selection as part of their overall defensive strategy.
