Sig Sauer P320-XTEN Endure Comp Handgun 10mm Auto 15rd Magazines(3) 3.8" Barrel Moss Green Slide Night Sights

The Sig Sauer P320-XTEN Endure Comp is a full-size 10mm handgun built for hunters, backcountry shooters, and anyone who demands a pistol that won't quit in harsh field conditions. This compensated 10mm combines serious stopping power with a 3.8-inch barrel optimized for accuracy, making it at home on the range, in the woods, or wherever your adventure takes you. The Moss Green Cerakoted slide features an exclusive laser-etched topographic pattern—both functional corrosion protection and a nod to the rugged terrain where this gun earns its keep.

Every detail speaks to durability and control in demanding conditions. The stainless steel slide and frame are paired with an aggressive laser-stippled grip module that holds firm even when wet or gloved. The flat striker-fired trigger breaks clean, while XRAY3 Day/Night Sights let you shoot from dawn into dusk without switching optics. The slide is optics-ready with PRO footprint mounting, so you can add your preferred red dot without modification. An M1913 accessory rail gives you room to mount a light or laser—essential for serious field work.

Capacity matters when you're reaching for a 10mm: you get three 15-round steel magazines in the box, giving you 45 rounds on hand plus one in the chamber. That's the kind of ammunition supply serious shooters and hunters appreciate. Weighing 32.3 ounces loaded, the XTEN Endure Comp handles well despite its full-size frame, and the 7.6-inch overall length stays manageable for duty or backcountry carry.

This is a purpose-built pistol from Sig's Custom Works division—not a compromise between caliber, capacity, and ruggedness, but a deliberate answer to shooters who refuse to sacrifice any of those things. If you hunt large game, run serious defensive loads, or simply trust 10mm stopping power, the P320-XTEN Endure Comp is built for you.
