Sig Sauer P365X 9mm Pistol 12+1 Capacity 3.1" Barrel Romeo Zero

The Sig Sauer P365X delivers micro-compact concealment with full-size capacity, combining a 12+1 round magazine with a 3.1-inch barrel in a frame designed for all-day carry. This striker-fired pistol addresses the traditional trade-off between concealability and firepower through advanced engineering and premium materials.

What Makes This Different

The P365X features Sig's XSeries flat trigger for improved control and a factory-installed Romeo Zero red dot optic for rapid target acquisition. Unlike standard micro-compacts that sacrifice capacity for size, this model maintains a 12+1 capacity while measuring just 5.8 inches overall. The extended grip module provides full three-finger purchase without printing under concealment garments.

Key Features

• 12+1 capacity with flush-fit magazine in micro-compact frame
• Factory Romeo Zero 3 MOA red dot optic pre-installed
• XSeries flat trigger with 90-degree break and short reset
• Stainless steel slide with Nitron finish for corrosion resistance
• Night sights co-witness with red dot for backup aiming
• Modular grip system accepts P365 family accessories and holsters

Field performance demonstrates consistent accuracy with the 3.1-inch barrel delivering 2.5-inch groups at 25 yards with quality ammunition. The Romeo Zero optic maintains zero through 500+ round sessions and functions reliably in temperatures from -10°F to 140°F. Law enforcement agencies report successful qualification scores with minimal training transition from duty pistols.
