The compact-length P320-M18 format brings a 3.9 inch slide and barrel, striker-fired action, and an ambidextrous manual thumb safety. The slide is optics-ready and includes front and rear cocking serrations. The optic cut is exposed with no cover plate installed. Note: The slide currently installed is not the standard M18/M17 pattern with the rear sight integrated into the optic cover plate; it uses a separate rear sight dovetail, so a rear sight remains installed with the optic cut open.
Current sights are fixed 3-dot tritium night sights that provide low-light visibility. The slide wears a durable Coyote PVD finish that matches the Coyote polymer frame.
This example is customized with a Wilson Combat P320 carry-size polymer grip module featuring Wilson Combat branding and starburst texturing. A flat-faced trigger shoe is installed to complete the setup.
Chambered in 9mm Luger with a listed capacity of 21+1, it ships with one extended 21-round steel magazine. The serialized FCU is visible through the grip-window, and the case label shows model code 320CA-9-M18-MS with a date of 09-Oct-2023. Made in the USA.
