SIG Sauer P320 Full Size 9mm 4.7" Optics Ready 10rd Black

The SIG Sauer P320 Full Size delivers striker-fired reliability with optics-ready versatility for professional and civilian applications. This 9mm platform combines a 4.7-inch barrel with SIG's proven modular fire control unit for consistent accuracy and adaptability.

What Makes This Different

The P320's modular design allows complete customization of grip size, caliber, and barrel length without requiring a new serialized frame. The optics-ready slide accepts popular red dot sights without machining, while the flat trigger provides a crisp break at approximately 5.5 pounds. Unlike traditional pistols with fixed frames, this system adapts to different hand sizes and mission requirements through interchangeable grip modules.

Key Features

• Striker-fired action with safe action trigger system and no external safety
• Optics-ready slide cut compatible with Romeo1Pro, DeltaPoint Pro, and similar footprints
• 4.7-inch stainless steel barrel with 1:10 twist rate for 9mm Luger
• Medium grip module fits most hand sizes with aggressive texturing
• Night sight compatible dovetail cuts front and rear
• Reversible magazine release accommodates left-handed shooters
• 10-round magazine capacity meets restricted state requirements

Field performance centers on the P320's consistent trigger pull and balanced weight distribution. The full-size frame provides stability for precision shooting while maintaining manageable recoil impulse. Law enforcement agencies report reliable function through 20,000+ round service cycles, with the nitron-finished slide resisting corrosion in harsh environments. Competition shooters appreciate the consistent lockup and minimal barrel movement during rapid fire strings.
