Key Features

• ENDURE Series Build: This pistol is the flagship of SIG Custom Works’ ENDURE line, meaning it’s built to resist corrosion and wear from moisture, dirt, and heavy use. Why it matters: You get a gun that won’t fail when you’re miles from a workbench.
• LXG Laser-Stippled Grip Module: The grip features an aggressive laser-stippled texture that locks into your hand even with wet gloves. Why it matters: No slip, no compromise on control during rapid fire or in rain.
• X-RAY3 Day/Night Sights: Tritium inserts with a bright green front ring provide instant sight acquisition in low light. Why it matters: You can shoot accurately at dawn, dusk, or inside a dark structure without a light.
• Optics-Ready Slide: The slide is pre-milled for direct mounting of popular red dot sights (e.g., RMR, Delta Point Pro). Why it matters: You can easily upgrade to a dot for faster target transitions without sending the slide out.
• 5-Inch Barrel with 10mm Power: The 5-inch barrel maximizes velocity from the 10mm Auto cartridge, delivering over 700 ft-lbs of energy with quality loads. Why it matters: You get authoritative stopping power against large game or two-legged threats.

Who It’s For

This pistol is for the shooter who heads into bear country, works in wet environments, or trains hard and needs a gun that won’t rust or slip. It’s also ideal for the 10mm enthusiast who wants a factory-built, optics-ready platform without sending slides off for custom work. New shooters stepping up from 9mm will appreciate the flat trigger and X-RAY3 sights that make the 10mm recoil manageable.

Pros and Cons

• Pro: Three 15-round magazines included – that’s 45 rounds of 10mm right out of the box.
• Pro: LXG grip texture works even with wet hands; no need for Talon grips or stippling.
• Pro: X-RAY3 sights are bright and durable; no batteries needed.
• Con: The aggressive grip texture can be uncomfortable against bare skin for concealed carry – plan for a cover garment or undershirt.

Frequently Asked Questions

Is the Sig Sauer P320 XTEN Endure optics-ready?

Yes. The slide is pre-milled with a removable cover plate, compatible with Trijicon RMR, Leupold Delta Point Pro, and other common footprints. You’ll need the correct mounting screws (included with most optics).

What holsters fit the P320 XTEN Endure?

Any P320 full-size holster with an open muzzle or a 5-inch barrel channel will fit. The XTEN uses the same frame dimensions as the P320 Full Size. Check with your holster maker to confirm fit for the LXG grip texture.

Does the ENDURE finish resist rust?

Yes. The Cerakote Elite coating is salt-spray tested to 200+ hours per manufacturer specs. The topographic etching also helps shed moisture. Still, wipe it down after exposure to saltwater or sweat.

What is the magazine capacity?

It ships with three 15-round magazines. The 10mm XTEN uses a dedicated magazine design; P320 9mm magazines will not work.

Is this a good gun for beginners?

It depends. The 10mm recoil is stout, but the X-Series flat trigger and low bore axis make it easier to shoot accurately than some other 10mms. New shooters should start with lower-recoil loads like 180-grain FMJ and practice grip fundamentals.
