As the 10mm resurgence continues across both law enforcement and civilian markets, the Sig Sauer P320 XTEN has quickly positioned itself as one of the most capable polymer-frame 10mm pistols available today. Built on Sig’s modular P320 platform, the XTEN blends familiar ergonomics with serious ballistic performance.
The heart of the XTEN is its 5-inch heavy-profile barrel, tuned to take full advantage of 10mm Auto’s energy potential. Whether running defensive loads, hard-cast for outdoors protection, or duty-grade ammunition, the XTEN maintains stability and accuracy even under stout recoil.
Sig enlarged and reinforced the slide assembly specifically for 10mm operation, and the grip module has a slightly extended geometry for improved recoil control. Paired with Sig’s X-Series trigger, the pistol offers a crisp, predictable break that helps maintain precision through faster strings of fire.
The XTEN is optics-ready and supports a variety of red-dot footprints, making it a strong choice for duty use in agencies exploring 10mm for specialized roles. Its 15-round capacity offers a meaningful advantage over more traditional 10mm handguns, placing the XTEN at the top of the class in terms of firepower.
For backcountry defense, law enforcement applications, or shooters wanting a modern, reliable 10mm that handles like a full-size service pistol, the P320 XTEN stands out as a robust, feature-rich offering in the high-powered handgun category.
