Sig Sauer P320-M18 Carry 9mm Threaded Barrel Package – Coyote-Tan, Manual Safety, Night Sights, 21+1
The P320-M18 Carry brings the U.S. military’s M18 side-arm design to the civilian market in a modular, suppressor-ready package. Finished in factory coyote-tan PVD and equipped with a 4.5-inch threaded barrel, this striker-fired pistol offers duty-grade capacity, raised night sights that clear a suppressor, and an ambidextrous manual safety that aligns with agency requirements. A removable Fire Control Unit (FCU) lets the owner swap calibers and grip sizes without a new transfer, adding long-term versatility.

The coyote-tan PVD slide features front and rear cocking serrations and an optic-ready rear plate that removes to accept popular red-dot footprints. Raised tritium night sights provide a bright sight picture in all lighting and co-witness above a suppressor when the threaded barrel is installed.
The polymer carry-size grip module offers a balanced feel while housing high-capacity 17- and 21-round magazines. A molded accessory rail accepts lights or lasers without adapters, and the reversible magazine release supports both right- and left-handed shooters.
Internally, the modular stainless-steel FCU is serialized, allowing caliber or frame swaps without additional paperwork. The striker-fired action delivers a consistent trigger pull, and the ambidextrous manual thumb safety meets many departmental policies.
This package ships with both a threaded barrel and a standard length barrel, letting the owner run suppressed, install a compensator, or return to duty length without tools. Combined with its military lineage, night sights, and coyote finish designed for reduced IR signature, the P320-M18 Carry stands out as a flexible, mission-ready sidearm.
