This commercial M18 variant follows the military specification, featuring a 3.9-inch carbon-steel barrel treated with a corrosion-resistant nitride finish for long service life.
The coyote PVD-coated slide includes front and rear cocking serrations, an external extractor, and a removable optic plate that fits DeltaPoint Pro, Romeo1Pro, and Romeo-X Pro footprints, letting you mount a red-dot sight without gunsmithing.
A modular polymer grip module in matching coyote tan houses the removable fire-control unit, allowing future caliber or size conversions. Ambidextrous controls—thumb safety and slide catch—support both right- and left-handed operation.
The flat, skeletonized trigger promotes a straight-to-the-rear pull, while SIGLITE tritium night sights (5.8-inch radius) provide 24-hour visibility. A three-slot MIL-STD-1913 rail accepts weapon lights or accessories.
