The P320-M18 configuration delivers the compact 3.9 in barrel length and coyote tan finish associated with the service M18 lineage, paired here with three 21-round magazines for a 21+1 capacity. Its modular P320 architecture centers on a removable, serialized fire control unit, allowing the grip module and other components to be changed while keeping the core trigger group.
Controls are duty-focused, with an ambidextrous manual thumb safety and a reversible magazine release. The striker-fired system uses a curved trigger, and a loaded-chamber indicator offers a clear status check at a glance. The glass-reinforced polymer frame is finished in coyote to match the slide.
Sighting is straightforward and durable: fixed 3-dot iron sights with a SIGLITE front night sight and a fixed rear on a removable plate. The slide is optic-ready via the removable rear-sight plate, giving the option to mount a compatible optic if desired.
The coyote tan PVD slide includes front and rear cocking serrations for positive manipulation. A 3-slot MIL-STD-1913 accessory rail on the dust cover supports common weapon-mounted accessories. The 1:10 RH twist barrel and excellent bore condition round out a compact, duty-style package made in the USA.
