The Legion-configured slide is optics-ready with a cover plate and uses the ROMEO1Pro/ROMEO2 footprint. It includes front and rear serrations for confident manipulation, XRAY3 day/night tritium sights (green-ring tritium front dot and two-dot tritium rear), and the Legion chevron on the slide. The patent-pending slide-integrated expansion chamber and twin top ports are designed to reduce felt recoil.
The full-size AXG aluminum grip module delivers a solid in-hand feel and comes finished in matching Legion Gray Cerakote. It includes replaceable textured grip panels and a backstrap, a removable flared magwell for quicker reloads, and ambidextrous slide-catch levers.
This striker-fired P320 variant uses a flat-faced, skeletonized trigger and the modular P320 fire control unit architecture, allowing grip, slide, and barrel swaps within the P320 platform. An integral three-slot accessory rail supports common lights or lasers.
Key dimensions include a 3.9 in barrel, overall length of 8.2 in, height of 5.5 in, and width of 1.6 in. Weight with magazine is 36.1 oz. Capacity is 17+1. The slide and frame both wear Legion Gray Cerakote, and the pistol is made in the USA.
