Sig Sauer M18X 9mm Pistol w/ Romeo M17 Optic 21+1 3.9" Barrel

The Sig Sauer M18X delivers military-proven performance in a civilian-legal configuration, combining the reliability of the M18 platform with enhanced features for serious shooters. This optics-ready pistol bridges the gap between duty-grade reliability and competitive shooting precision.

What Makes This Different

The M18X incorporates the same modular chassis system used in military contracts, allowing frame size customization without replacing the entire firearm. The Coyote PVD coating provides superior corrosion resistance compared to standard Cerakote finishes, while the serrated stainless steel slide reduces glare and improves grip during rapid manipulation. The included Romeo M17 optic eliminates the need for aftermarket sight upgrades.

Key Features

• Romeo M17 red dot optic with 3 MOA dot for rapid target acquisition
• Modular grip system accommodates multiple hand sizes with interchangeable frames
• 21+1 capacity with flush-fitting magazines for extended engagement capability
• Picatinny rail accepts standard tactical accessories and weapon lights
• Optics-ready slide cut accepts multiple red dot footprints without modification

Field performance demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition, while the striker-fired action provides a consistent 6.5-pound trigger pull. The stainless steel slide maintains dimensional stability across temperature extremes from -40°F to 140°F. Law enforcement agencies report function rates exceeding 99.8% through 10,000-round test protocols.
