Sig Sauer P320 XTEN | 10mm | SIg-Loc Pro Red Dot | 15rd Pistol

The Sig Sauer P320-XTEN (MPN: 320X5-10-BXR3-RXSL) is the ultimate powerhouse in the P320 lineup, specifically engineered to harness the formidable energy of the 10mm Auto cartridge. This isn't just a caliber conversion; it is a ground-up performance build designed for hunters, backcountry hikers, and tactical shooters who demand the "stopping power" of a magnum revolver with the high-capacity advantage of a modern striker-fired pistol.

XSeries Ergonomics & 10mm Performance

The XTEN features the redesigned XSeries 10mm/45 Grip Module, which provides a deeper undercut and an extended beavertail for superior recoil management. Despite the larger caliber, the grip remains remarkably slim, allowing for a comfortable and secure purchase even during rapid fire. The 5-inch bull barrel provides the necessary mass to stabilize heavy 10mm loads while maximizing muzzle velocity and long-range accuracy.

Factory-Equipped with SIG-LOC Pro Optics

This premium configuration comes factory-installed with the SIG SAUER SIG-LOC Pro Enclosed red dot sight. Built with a rugged 7075 aluminum housing, the ROMEO-X Enclosed protects the emitter from mud, rain, and debris, ensuring your aiming point remains clear in the harshest environments. Featuring MOTAC (Motion Activated Illumination) and a side-mounted battery tray, this optic is purpose-built for duty and backcountry reliability.
