SIG Sauer P320 Pro 9mm 3.9" 16-Round Pistol

The SIG Sauer P320 Pro 9mm 3.9" 16-Round Pistol is a refined striker-fired platform purpose-built for law enforcement, military, and civilian tactical professionals who demand a duty-grade handgun with proven reliability and ergonomic excellence. This compact-to-midsize 9mm combines the modular P320 system's versatility with Pro-series refinements, making it an ideal choice for patrol officers, plainclothes operators, and serious civilian shooters seeking a balanced carry gun with minimal recoil impulse.

The P320 Pro platform has earned its place in the hands of military special operations units and major U.S. law enforcement agencies, reflecting decades of combat and street-proven performance. The 3.9-inch barrel geometry produces a velocity sweet spot for 9mm duty ammunition while maintaining the compact handling characteristics that define the Pro series—optimal sight radius without sacrificing concealability or on-body weight distribution. The flat trigger delivers consistent, predictable break geometry critical for accurate rapid fire, while the integrated Picatinny rail enables mounting of modern tactical lights and lasers essential for low-light engagement.

SIG's pre-cocking striker design ensures consistent trigger performance and simplified safety protocols, and the modular fire control unit allows customization of grip modules in different sizes and colors, accommodating a wide range of hand sizes and allowing transition between personal and duty configurations. This versatility makes the P320 Pro an excellent choice for those who require adaptability in various shooting scenarios, whether for duty or personal defense.
