This P320-M18 pairs a compact 3.9 in slide with a carry-length grip module for balanced handling and control. The coyote-tan slide and grip module are matched with darker controls, mirroring the visual profile associated with the M18 configuration.
The modular P320 steel fire control unit (FCU) is the serialized component and is visible through the grip window, enabling the platform’s well-known adaptability. Controls include an ambidextrous manual safety and a reversible magazine release. A loaded chamber indicator at the rear of the ejection port provides a quick visual cue.
Sight and slide features are duty-focused: 3-dot sights with a luminous front dot, front and rear slide serrations, and a rear sight/plate unit with a removable plate and mounting screws that provides an optic-ready footprint.
The dust cover houses a 4-slot MIL-STD-1913 accessory rail for lights or other compatible devices. The striker-fired, short-recoil action runs a 10+1 capacity in 9mm Luger. Construction includes a glass-reinforced polymer grip module and a steel receiver, with U.S. manufacture noted.
