The P320-M18 format delivers a compact 3.9 in barrel, striker-fired operation, and the P320's modular FCU, allowing the fire control unit to be the serialized core of the system. This example includes ambidextrous manual thumb safeties and an internal striker safety.
A Wilson Combat P320 polymer grip module is installed, bringing an aggressive starburst texture, an extended beavertail, and an undercut trigger guard. The design supports confident handling and control in a compact footprint.
The coyote-tan slide is optics-ready with a removable cover plate over the optics cut, and it includes front and rear serrations and an external extractor. The pistol uses a stainless steel receiver and a black polymer frame with a MIL-STD-1913/Picatinny accessory rail for lights or lasers.
Capacity is 21+1 with the included 21-round magazines, and a 17-round magazine is also provided. The supplied magazines are steel and marked 'MADE IN ITALY,' with the 17-round magazine featuring a tan, extended-style basepad and the 21-round magazines using standard black baseplates. Made in the USA, this configuration reflects the M18 lineage in a compact, carryable package.
