The Sig Sauer P320-XTEN Endure is a 10mm full-size striker-fired pistol engineered for hunters, backcountry shooters, and outdoor professionals who demand a sidearm that can handle extreme conditions. Built on the modular P320 platform, the XTEN Endure pairs a 5-inch carbon steel barrel with a fully Cerakoted stainless steel slide featuring a laser-etched topographic pattern—functional art that resists corrosion and UV fade in sun, snow, and dust. This is a gun designed for adventure, not the range mall.
The optics-ready slide uses the PRO footprint (DeltaPoint Pro compatible), so you can mount your preferred red dot without gunsmith work. Factory-installed X-RAY3 Day/Night Sights deliver both daylight and low-light capability, and the frame rides on a stainless steel chassis for durability where weight matters less than reliability. The ENDURE XSeries grip module—exclusive to this line—features aggressive LXG laser stippling that bites hard even when wet, paired with a flat XSeries trigger for a crisp, controllable break.
Chambered in 10mm Auto, the P320-XTEN Endure comes with three 15-round steel magazines, giving you serious capacity for backcountry defense or extended field shooting. At 33 ounces loaded and 8.5 inches overall length, it's a serious full-size carry gun that still fits modern holsters. The accessory rail accepts lights and lasers for those who want to go further into the dark.
