SIG Sauer P320 XFull 9mm 3.9" Barrel 10-Round Black Pistol

The SIG Sauer P320 XFull delivers enhanced grip ergonomics and improved trigger performance in a striker-fired platform engineered for serious shooters. This 9mm variant combines the proven P320 modular fire control unit with XSeries refinements that elevate accuracy and handling characteristics.

What Makes This Different

The P320 XFull incorporates a deeper undercut trigger guard and enhanced grip texture that provides 30% more surface contact compared to standard P320 models. The XSeries flat trigger reduces travel distance by 20% while maintaining the consistent 5.5-6 pound pull weight that made the P320 platform the choice of military and law enforcement agencies. Unlike polymer-framed competitors, the modular fire control unit allows complete customization of grip size, barrel length, and caliber without requiring additional background checks.

Key Features

• Modular striker-fired system with serialized fire control unit for easy customization
• 3.9-inch stainless steel barrel with 1:10 twist rate for optimal 9mm performance
• XSeries flat trigger with crisp break and short reset
• Enhanced grip module with aggressive texturing and improved ergonomics
• SIGLITE night sights with tritium inserts for low-light accuracy
• Ambidextrous slide catch and reversible magazine release
• M1913 Picatinny rail for lights and laser accessories

Field testing demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition, while the enhanced grip texture maintains control during rapid-fire sequences. The 10-round magazine capacity meets restricted state requirements without compromising reliability. Weather sealing protects internal components from moisture and debris during extended outdoor use, making this suitable for duty carry, competitive shooting, and personal protection applications.
