🔥 Key Features and Benefits:
✅ Chambered in 10mm Auto – Power & Penetration
The 10mm Auto cartridge is known for its powerful ballistics, offering deep penetration and stopping power suitable for dangerous game or defensive scenarios. The P320 XTEN brings this high-energy round into SIG’s modular platform, giving shooters a serious edge in both firepower and ballistic reach.
Whether you’re hunting wild boar, hiking in bear country, or simply want a powerful pistol for range or home defense, this pistol gives you confidence when it matters most.
✅ 5-Inch Bull Barrel – Enhanced Accuracy and Control
The match-grade 5-inch barrel provides excellent velocity for the 10mm round while contributing to the firearm’s accuracy and overall balance. Its bull barrel design improves rigidity and heat management, allowing you to maintain tight shot groups even during extended range sessions.
✅ ROMEO2 Red Dot Optic – Target Acquisition Redefined
The factory-installed SIG SAUER ROMEO2 red dot sight transforms this pistol into a precision platform. Designed to withstand the recoil of 10mm rounds and field conditions, the ROMEO2 features a crisp 3 MOA red dot, waterproofing, and a rugged aluminum housing. Fast target acquisition, extended eye relief, and better accuracy under stress make the ROMEO2 ideal for tactical or outdoor use.
✅ XSeries Grip Module – Ergonomics and Recoil Mitigation
SIG’s XSeries grip module brings enhanced ergonomics and a deeper undercut trigger guard for superior control. With its full-sized frame and aggressive texturing, it allows for a firm grip that absorbs recoil and provides quick follow-up shots. Combined with the flat-faced XSeries trigger, it offers a consistent, short reset and a clean break that supports accurate shooting under pressure.
✅ 15+1 Capacity – Extended Firepower
With a 15-round magazine capacity in 10mm Auto, the P320 XTEN offers ample firepower for field encounters or high-stakes defensive situations. That’s significantly more than many traditional 10mm handguns, giving you more rounds before a reload is needed—without increasing the grip size excessively.
✅ Optics-Ready & Modular – Built for Customization
As part of the modular P320 platform, this pistol allows shooters to swap slides, barrels, and grip modules with ease. Whether you’re customizing for competition, concealment, or tactical use, the P320 XTEN’s modularity ensures it can adapt to your needs. The optics-ready slide is pre-cut for SIG’s ROMEO2 and other compatible reflex sights, and the rear sight remains co-witnessed.
✅ Night/Day Ready – X-RAY3 Sights
Even with the ROMEO2 red dot installed, the X-RAY3 day/night suppressor-height sights allow for quick target alignment in any lighting condition and provide a backup aiming system should your optic fail.
🏹 Perfect for a Variety of Uses:
-
Backcountry Carry: Defend against predators with a hard-hitting round and dependable optics.
-
Home Defense: High-capacity, fast-targeting pistol to secure your home with confidence.
-
Duty or Tactical Use: Rugged enough for law enforcement and military-style missions.
-
Recreational Shooting: Enjoy the power of 10mm with smooth shooting and great ergonomics.
-
Hunting: Take down medium-sized game with a handgun that has reach and punch.
🛡️ Built Like a Tank – SIG Reliability
The P320 XTEN is designed to meet SIG SAUER’s rigorous testing standards. From drop tests to dust and sand exposure, this pistol proves its mettle in extreme conditions. The internal stainless steel chassis and nitron-coated slide ensure long-lasting durability.
