The P320-M18 format delivers a compact slide with a carry-length grip, pairing easy handling with a 17-round magazine. Its coyote tan PVD slide and matching coyote-tan polymer grip module echo the M18 aesthetic while maintaining duty-focused function and durability. Made in the USA, this example preserves the core P320 ergonomics and capacity in a carry-friendly package.
The slide is optic-ready, with a removable rear-sight plate cut to the DeltaPoint Pro pattern per factory literature. It includes front and rear serrations for confident manipulation. SIGLITE 3-dot night sights are installed, with steel blades marked "8" front and rear.
Built around SIG’s modular stainless-steel fire control unit, this pistol supports straightforward configuration changes. It uses a striker-fired action with an internal striker safety and includes ambidextrous slide catch levers. An accessory rail is integrated into the frame for compatible lights or add-ons.
This pistol is currently configured without a manual thumb safety. Included in the case are an additional coyote-tan grip module and a separate P320 manual safety selector, providing the parts needed for a safety-equipped setup if preferred.
The 3.9-inch barrel and compact slide balance sight radius and concealability. A 17-round steel magazine is included, and the removable night-sight rear plate aligns with the M18 layout and factory specification.
