The TXG tungsten-infused polymer XSeries grip module is a defining feature of the Legion series. On this XFive Legion R2, it yields an unloaded weight of approximately 43.5 oz and is finished in Legion Gray to match the slide. The grip module includes a flared, removable magwell, a pronounced beavertail, and an undercut trigger guard.
A 5 in carbon steel bull barrel anchors the system, paired with the P320’s striker-fired action and a flat, skeletonized trigger. Capacity is 17+1 in 9mm Luger, and this is the full-size configuration.
The Legion Gray slide incorporates lightening cuts and the Legion chevron. The R2 optics-ready cut supports the SIG ROMEO1PRO and Leupold DeltaPoint Pro footprint. Dawson Precision sights include a green fiber-optic front and an adjustable rear mounted on a removable plate, allowing you to maintain adjustable irons with the plate installed.
Controls and features include ambidextrous slide catch levers and an M1913 accessory rail. The modular P320 FCU architecture allows grip, slide, and barrel swaps within the platform, providing flexibility for configuration changes as needed.
