SIG Sauer P320 XTEN 10mm Compact 3.8" 15rd Optic Ready Black

The SIG Sauer P320 XTEN delivers 10mm power in a striker-fired platform engineered for serious applications. This optic-ready pistol combines the proven P320 modularity with enhanced engineering to handle the demanding 10mm Auto cartridge reliably.

What Makes This Different

Unlike standard P320 models, the XTEN features a reinforced steel frame insert and enhanced recoil management system specifically designed for 10mm pressures. The slide assembly incorporates additional mass and optimized spring rates to cycle consistently with both light target loads and heavy hunting ammunition. Factory testing demonstrates reliable function across grain weights from 155 to 200 grains.

Key Features

• 10mm Auto chambering with 15-round magazine capacity
• 3.8-inch barrel length optimized for 10mm ballistics
• Optic-ready slide cut compatible with Romeo1PRO and similar footprints
• XSeries grip module with enhanced texture and ergonomics
• Striker-fired action with 90-degree break and short reset
• Modular FCU allows caliber conversions and grip changes

Field performance demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition. The 10mm chambering provides effective terminal performance for hunting medium game, personal protection, and outdoor applications where maximum stopping power is required. The pistol functions reliably in temperatures from -40°F to 140°F and continues operating after exposure to sand, dust, and moisture.
